I/O Pair-Connection
The I/O Pair-connection function is used to create a digital input to digital output pair through the
Ethernet. Once the configuration is complete, the PETL/tET/tPET series modules can continuously poll
the status of a remote digital input device using the Modbus TCP protocol, and then write to the local
digital output channels in the background.
