13.2.1.8 8 Channel Digital Input Module PTC with Diagnostics and Output
Process Data
750-1425
The digital input module PTC provides via one logical channel 2 byte for the input and output process image.
The signal state of PTC inputs DI1 … DI8 is transmitted to the fieldbus coupler/controller via input data byte D0.
The fault conditions are transmitted via input data byte D1.
The channels 1 … 8 are switched on or off via the output data byte D1.
The output data byte D0 is reserved and always has the value “0“.
