Premium TSX P57 automated platform processors manage the entire PLC station, which is made up of "Discrete" Input/Output modules, analog Input/Output modules and application-specific modules. These can be distributed over one or several racks connected to the X Bus or the field bus.
Premium TSX H57 are dedicated to Hot Standby applications. A premium Hot Standby system consists of two identical PLC stations distributed over one or several racks. One of the two PLCs functions as the Primary controller and the other one as the Standby controller.
Example of 2 Premium PLC stations:
NOTE: If the second rack does not contain a processor module, this is a single PLC station distributed on 2 racks.
