Modbus.

PrintFaqtory’s provides a subset of the industry standard TCP/IP Modbus interface that responds to FC3 (read holding registers) with the first defined report having a DeviceID of 2, the second report has an ID of 3, etc.

This interface is provided primarily for Modicon PLC sites but is applicable for any Modus enabled network. It is very unlikely that this interface would be applicable to a non PLC (laboratory) site.

Below is a sreenshot of PrintFaqtory’s Modbus tab. Live input/output Modbus data is displayed for verifying/debugging the Modus data.
