Auxiliary Transducer Block Auxiliary Transducer block provides advanced configuration support of Linearization, Volume and Correlation Algorithm. It also provides support to view the Echo curve. 3.6.1. Linearization When the Linearization option is enabled, the transmitter’s measured values are replaced by corresponding user-specified corrected values from the linearization table.
3.6.3. Echo Curve Types The Honeywell SLG 700 captures four types of echo curves: Windowed Echo Curve Full Echo Curve Processed Full Echo Curve Background Substraction Array Echo Curve ATTENTION When DTM is opened, Echo curve page under RLAUXTB will take about 30 sec to update parameter list during the update time the page will show blank.
Full Echo Curve: This echo curve type includes data collected over the full length of the probe. Subtraction of background reflections near the reference plane is not applied so all physical reflections, due to a nozzle for instance, will be visible. This type of echo curve is useful for troubleshooting problems in the region near the reference plane.
Processed Full Echo Curve: Similar to the Full Echo Curve type, but with subtraction of background reflections near the reference plane applied. This type of echo curve is useful for process and/or algorithm troubleshooting. Figure 5: Processed (Full) Echo Curve Background Subtraction Array Selecting this echo curve type allows the data array that is used to remove unwanted reflections in the region near the reference plane to be uploaded and viewed.

DISPLAY_MESSAGE A message with a maximum of 64 characters that appears on the Advanced Display of the transmitter.
3.9 Analog Input block The Analog Input (AI) block takes the transducer’s input data, selected by channel number, and makes it available to other function blocks at its output. The variables to be used by the block are defined through the available channels: ...
Figure 13: Analog Input Block Schematic Diagram The OUT_SCALE is normally the same as the transducer, but if L_TYPE is set to Indirect or Ind Sqr Root, OUT_SCALE determines the conversion from FIELD_VAL to the output. PV and OUT always have identical scaling. OUT_SCALE provides scaling for PV. The block places the value in OUT if the mode is AUTO.
Page 88
PV Value The AI block PV value is determined based on the selected transducer channel’s PRIMARY_VALUE. AI OUT AI in Manual Mode When the AI block is in manual mode, OUT can be written as a fixed value between -10% and +110% of the OUT_SCALE range.
Parameters List Table 14: Analog Input block parameters Parameter Description ST_REV The revision level of the static data associated with the function block. The revision value is incremented each time a static parameter value in the block is changed. TAG_DESC The user description of the application of the block.
Page 90
Parameter Description L_TYPE The state (Direct or Indirect) values that are passed from the transducer block to the AI block. When L_TYPE = Direct, the values are passed directly from the transducer block to the AI block. (No units conversion.) When L_TYPE = Indirect, the values from the transducer block are in different units, and must be converted either linearly (Indirect) or in square root (Ind Sqr Root) using the range defined by the transducer and the OUT_SCALE range.
Attributes Supported Modes The block supports the following modes: AUTO (Automatic) MAN (Manual) OOS (Out of Service). Alarm Types The block supports standard block alarms (see section 3.2). Additionally it supports, standard HI_HI, HI, LO, and LO_LO alarms applied to OUT.
3.10 Proportional Integral Derivative (PID) block with auto tune The PID block is the key to many control schemes, and it is commonly used. The PID function integrates the errors. If there is difference in process time constants of a primary process and secondary process measurement, then the block can be cascaded if required.
Execution The Process Variable to be controlled is connected to the IN input. The value is passed through a filter, and its time constant is PV_FTIME. The value is then shown as the PV, which is used in conjunction with the SP in the PID algorithm. A PID does not integrate if the limit status of IN input is constant, or if further control action based on the PID error proceeds IN input further towards its active status limit.
Page 94
The PID block allows you to choose either a standard PID control equation (Ideal) or a robust PID equation defined by Honeywell. This selection is defined in the PID_FORM parameter. The output has three terms, namely Proportional, Integral, and Derivative. The output is adjusted by tuning constants.

3.10.3. Auto tuning Cycle tuning The PID block supports the Cycle tuning algorithm. In Cycle tuning, the tuning parameter values are derived from the process response to the resultant action of causing the PV to oscillate about a SP value. The tuning method uses the measured ultimate gain and period to produce tuning parameter values, by using the relationship developed by Ziegler Nichols equations.

TUNE_REQ Tuning Request performs auto tuning process. Auto Tune Indicator indicates Auto tune ON/OFF. AT_MODE Auto Tune Mode supports two options: AT Ready, Inactive ...
3.11 Input Selector block The Input Selector block performs maximum, minimum, middle, average and ‘first good’ input selection. The Input Selector block provides selection of up to four inputs and generates an output based on the selected type of input. The block normally receives its inputs from AI blocks, and provides a combination of parameter configuration options.
Figure 17: Input Selector Schematic Diagram If SELECT_TYPE is Minimum, it transfers the lowest value to the output of the block. The value of SELECTED is the number of the input with the lowest value. If SELECT_TYPE is Maximum, it transfers the highest value to the output of the block. The value of SELECTED is the number of the input with the highest value.
Parameters List Table 17: Input Selector block parameters Parameter Description ST_REV The revision level of the static data associated with the function block. The revision value increments each time a static parameter value in the block is changed. TAG_DESC The user description of the application of the block. STRATEGY Used to identify grouping of blocks.
Parameter Description UPDATE_EVT This alert is generated by any change to the static data. BLOCK_ALM The block alarm is used for all configuration, hardware, connection failure, or system problems in the block. The cause of the alert is entered in the subcode field.
3.12 Integrator block The Integrator block integrates a variable as a function of time, and also accumulates the counts from a Pulse Input block. The block is used as a totalizer that counts up until reset or as a batch totalizer that has a setpoint, and the integrated or accumulated value is compared to pre-trip and trip settings.
The usage is as follows: Rate It is used when the variable connected to the input is a rate, that is Kg/s, w, Gal/hour, and so on. This input can come from the rate output OUT of an Analog Input block. Accum It is used when the input comes from the OUT_ACCUM output of a Pulse Input block, which represents a continuous accumulation of pulse counts from a transducer, or from the output of another...
Page 108
If the input option is Accum The Integrator block determines the number of additional counts from the counter input readings from the last execution. The difference in count is determined as follows: If the difference between the reading in one cycle and the reading in the preceding cycle is less than 500,000 or greater than (- 500,000), the difference must be taken as the variation.
Page 109
Integration of Inputs There are three internal registers used for the totalization: Total = The net increment is added every cycle, irrespective of the status. Atotal = The absolute value of the net increment is added every cycle, irrespective of status.
Page 110
Resetting the totals The block uses a discrete input RESET_IN to reset the internal integration registers. The operator can send a command to reset the same registers by making OP_CMD_INT = RESET. This is a momentary switch that turns-off when the block is evaluated. The option “Confirm Reset” in INTEG_OPTS, if set, prevents another reset from occurring until the value 1 has been written to RESET_CONFIRM.
Page 111
INTEG_OPTS: 0 (Flow reverse) When this option is selected, only reverse flows is considered for integration. If there is no reverse flow inputs (whose value is negative), and if one inputs is forward (whose value is positive) the integration continues. Note: If both the inputs are forward, then the integration stops.

3.14 Signal Characterizer block The Signal Characterizer block describes the input/output relationship for any type of function. The block has two paths, each with an output that is a non-linear function of the corresponding input. The non-linear function is configured based on a single look-up table with 21 arbitrary x-y pairs. To use the block in a control or process signal path, the status of an input is provided to the corresponding output.
To derive the output value that corresponds to the input, use the following formula, y = mx + c Where, m is the slope of the line. c is the y-intercept of the line Figure 23: Signal Characterizer Curve The values of x must increase sequentially for interpolation to be applicable.
Parameter list Table 20: Signal Characterizer block parameters Parameter Description ST_REV The revision level of the static data associated with the function block. The revision value is incremented each time a static parameter value in the block is changed. TAG_DESC The use description of the intended application of the block.
Attributes Supported The block supports the following modes: Modes AUTO (Automatic) MAN (Manual) OOS (Out of Service). Alarm Types The block supports standard block alarms, (see section 3.2). Status OUT_1 shows the status of IN_1 and OUT_2 shows the status of Handling IN_2.
3.15 Output Splitter block The output splitter block drives two control output signals from a single input signal. Each output is a linear function of a fraction of the input signal. The same linear function when used in reverse provides the back calculation support. For different combinations of input and output conditions, a decision table supports cascade initialization.
Figure 26: Split Range and Sequence Operation The examples shown do not show the full range of possibilities. The lines could overlap like an X, or both start from the origin but have different slopes. The endpoints do not have to lie within 0-100%. Limits in the external blocks may affect the useful range of a line.
A configuration error shall be set in BLOCK_ERR and the actual mode of the block shall go to Out of Service if the X values have any of the following conditions: X21 < X11, X12 <= X11, X22 <= X21. The parameter LOCKVAL provides an option to specify whether OUT_1 remains at its ending level when control is switched to OUT_2, or goes to Y11.

4. SLG 700 FF Level Transmitter operation 4.1 Operational considerations There are a number of considerations that must be noted when configuring a transmitter to operate in a fieldbus network. LAS Capability The transmitter is capable of operating as the Link Active Scheduler (LAS). The LAS is a fieldbus feature which controls traffic on the network, such as controlling token-rotation and coordinating data publishing.
4.2 Configuration of the transmitter using Handheld (HH) Figure 29 graphically represents the connection of the transmitter to the handheld. Each transmitter includes a configuration database that stores its operating characteristics in a non-volatile memory. The handheld is used to establish and/or change selected operating parameters in a Transmitter database.

Page 147
6.6.2. Process menu: This menu contains sub menus like Process configuration, Process variables and Trends as shown below. The Process configuration menu groups the most commonly modified parameters into five categories; Process, Measurement, Probe, Mounting & Attenuation. The parameters in these groups address the major site-specific configuration that might be needed during the commissioning of a transmitter.
Page 148
6.6.2.4 Process The four parameters in this group allow the products involved in the process of operating the tank to be identified, as shown. The first consideration to be made is the number of products involved, and secondly the dielectric constant of each product. The dielectric constant of a medium affects radar measurements in two ways: 1.
This configuration parameter allows the number of products in the tank to be identified. The available options are: Single Liquid: In this application the SLG 700 measures the level of one liquid product in the tank with a vapor, which is usually air, above the product. This application is shown in Figure 30.
Upper Product, as shown below in Figure 32. The SLG 700 measures the total level of the products in the tank as well as the level of the interface (boundary) between the two liquid products in the tank.
Page 151
6.6.2.5 Measurement Most customers are more interested in the height of the liquid surface or interface relative to some lower datum point, such as the bottom of the tank, rather than the transmitter’s reference plane. Measurements made relative to this lower, user-defined datum point are referred to as levels to distinguish them from the distances measured from the transmitter’s datum point.
Figure 33 shows the location of the Reference Plane, denoted as R, for the two basic methods of connecting the transmitter to the tank, either threaded or flanged. Refer to the Radar Level Measurement section in the SLG 700 Transmitter User’s manual #34-SL-25-11. Figure 33- Reference plane R for flanged and threaded connections...
Page 153
6.6.2.6 Probe Probe Type: Only adjust this if you are changing the type of probe. Adjustments to the calibration offsets and many other tuning parameters may be necessary if the probe is changed. The available options are: Custom, Rod, Wire, Multi-Twist Wire and Coax.
For more information on transitions zones for the various sensor configuration (i.e. coax, rope, rod, HTHP, etc.), refer to SLG 700 SmartLine Level Transmitter User’s manual, #34-SL-25-11. Table 23 - Minimum blocking distances and transition zones for the various probe types...
Page 155
Maximum Filling Rate: This parameter indicates the maximum rate at which the tank is expected to be filled or emptied. This allows the transmitter to collect data over the correct area of the probe so that the surface and/or interface positions can be tracked effectively and aids in the rejection of false reflections that might look similar to the correct reflections.
Page 156
Sensor Connection Type: Read-only parameter indicating how the Sensor Housing and Process Connector are connected together. In most cases these two components are connected end-to-end in the Direct mount mode. For harsh environments where the temperature at the Process Connector is too high for the electronics inside the Sensor Housing, a 3m Remote Mount cable is available to physically separate the electronics from the process connector.
Page 157
In addition obstacles present close to the wave guide can cause reflections that mimic levels. The SLG 700 transmitter utilizes a means of subtracting out these static background reflections before processing the data for reflections from the product(s).
Page 158
Full Tank Detection: Full tank detection enables the detection of a level within the upper blocking distance at startup and it ensures reliable measurement when the block distance high (BDH) is reduced below the transition upper distance. This feature enables the transmitter to perform additional analysis on the data in the region near the reference plane where the product reflections become mixed with reflections from the physical mounting components such as a flange or nozzle.
Page 159
Echo Lost timeout: This parameter allows for time adjustment when the transmitter waits in response to echo loss. Field Background Capture This method collects a new background echo for the selected type and length. This process should only be performed when there is no product in the region over which the background will be captured. The length of this region varies with the transmitter model, mounting location and probe type.
Page 160
On entering all the requested details the transmitter will start the capture sequence and in progress message will be displayed to show the progress. The function of the button will also change, as shown below, allowing the user to Abort the currently active method if required. Upon completion of the process, a pop-up message such as the one shown below will be displayed indicating whether the capture was successful or not.

Attenuation This sets the linear attenuation coefficient (Radar Pulse energy dissipation) of Lower Product. (For Two Liquids only). Upper Prod. Attenuation This sets the linear attenuation coefficient (Radar Pulse energy dissipation) of Upper Product (For Two Liquids, otherwise this is just Product/Surface attenuation).

Similarly screen 2 to 8 has the same parameters as like screen 1.
6.9 Auxiliary Transducer block configuration The Auxiliary Transducer block(RLAUXTB) menu items deal with fine tuning of the algorithms used inside the transmitter and generally do not need to be adjusted. However, in demanding applications or if the process or mounting configuration changed from what was ordered, some of the default options may need to be adjusted.
Page 173
6.8.5. Configuration: This menu contains sub menus like Linearization, Correlation Algorithm, Volume & Echo curve as shown in figure. Linearization This option allows users to adjust the level measurement to agree with a customer measurement. It is available only through the use of a PC-based DTM / DD. Configure the linearization table to make the transmitter output agree with an independent level measurement.
Page 174
Correlation Algorithm The method by which the distance to product surface and distance to interface is found is based on correlation between the measured echo curve and reflection models. The algorithm slides the models across the echo curve and at each step calculate the difference between the model and the echo curve, referred to as the Objective Function.
Reflection Models: The radar impulse reflection model is an asymmetric damped cosine function that takes four parameters as listed in the leftmost Reflection Models in above screen shot. The model and its gain, width and attenuation parameters are illustrated in Figure Go to section 3.6.5 for details on how to tune the parameters using HART DTM...
Page 176
The Process Connector model is only used in cases where the sensor housing is separated from the process connector by the optional 3m Remote Mount Cable. Since the remote cable may be subject to a high temperature gradient, a reflection within the process connector is used as the datum point for locating the transmitter’s Reference Plane, eliminating temperature dependences of the level measurement.
