Extent and application
Inputs are used, for example, to input external signals e.g. via pushbuttons,
key-operated switches, etc. These external signals are processed further
internally via appropriate connections. The system has different inputs
depending upon the device series:
Basic unit inputs (BU Inputs)
Operator panel buttons (OP Buttons)
Digital module 1 inputs (DM1 Inputs)
Digital module 2 inputs (DM2 Inputs)
Temperature module inputs (TM Inputs)
Analog module inputs (AM Inputs)
Acyclic Receive (Acycl. Receive)
