6.13 Configuration of the technology objects and I/O variables
6.13.3
Configuration of output cams / cam tracks
Overview
The type of cam output must be selected during the configuration of the TO outputCam and
TO camTrack.
The following output types are available:

Explanation
The cam output is performed on the basis of an internal time stamp. The temporal
resolution of the cam output depends on the hardware used.
Supported hardware:
SIMOTION D4x5-2 (terminal X142): Resolution 1 μs
•
TM17 High Feature: Resolution 1 μs
•
TM15: Typical resolution 125 μs (DRIVE-CLiQ cycle clock)
•
D410-2 (DI/DO 8 to 15):
•
Typical resolution 125 µs
The cam output is performed via onboard outputs of the SIMOTION CPU. The output
is via a hardware timer and the cam output is achieved with a resolution with respect to
time < servo cycle.
Supported hardware:
SIMOTION D4x5 (terminal X122, X132)
•
SIMOTION D410 (terminal X121)
•
SIMOTION C240, C240 PN (terminal X1)
•
The output cam calculations are performed in the processing cycle (IPO or IPO2 cycle
or in the servo cycle).
The actual cam output is performed in the servo cycle. The resolution with respect to
time of the cam output is generally reduced by the output cycle of the I/O used.
The resolution is therefore dependent as follows:
For the standard I/O (e.g. TMC, ET 200), on the cycle time of the bus system

(PROFIBUS DP / PROFINET IO)
For the TM15 / TM17, on the cycle time of the bus system (PROFIBUS Integrated /
•
PROFIBUS DP / PROFINET IO)
For the TM15 DI/DO, TM31, TM41, TB30, on the configured sampling time:
•
–
cu.p0799 (CU inputs/outputs sampling time) for the TB30 and onboard outputs
–
p4099 (TMxx inputs/outputs sampling time) for TM15 DI/DO, TM31 and TM41
Supported hardware:
Onboard outputs (SIMOTION D, controller extension CX, SINAMICS control unit
•
CU3xx)
Centralized I/O (SIMOTION C)
•
Distributed I/O via PROFIBUS DP / PROFINET I/O (e.g. TMC, ET 200, etc.)
•
Drive-related I/O (TM15, TM15 DI/DO, TM17 High Feature, TM31, TM41, TB30)
