12 POINT I/O 2 Current Output and 2 Voltage Output Analog Modules
Publication 1734-IN002E-EN-E - October 2016
Communicate with Your Module
POINT I/O modules send (consume) and receive (produce) I/O messages. You map these
messages into the processor’s memory.
These modules produce 2 bytes of input data (scanner Rx) (fault status). These modules
consume 4 bytes of output data (scanner Tx).
Message size: 2 Bytes
