Communicate With
Your Module
I/O messages are sent to (consumed) and received from (produced) the
module. These messages are mapped into the processor’s or scanner’s memory.
The module produces 1 or 2 bytes of input data (scanner Rx - status) based on
which produced assembly is selected. The default setup is 2 bytes.
Default Data Map - Produced Assembly Instance 101
ATTENTION
Make sure all connectors and caps are securely tightened to properly
seal the connections against leaks and maintain IP enclosure type
requirements.
To comply with the CE Low Voltage Directive (LVD), all connected I/O
must be powered from a source compliant with the following:
• Safety Extra Low Voltage (SELV) or Protected Extra Low
Voltage (PELV).
