Page 9: Overview
Overview Product overview The PSB modules are conceived for an EMS that is equipped with the EMS400S plant controller. Operating in combination with an S7-1200 CPU, the PSB modules act as a plant segment controller and carrier controller. Communication in the EMS is handled by the "PSB-S modules" and "PSB-C modules". These modules set up the connection for communication between the stationary and mobile sections of the unit. -
