Issue
EcoStruxure Operator Terminal Expert or Vijeo Designer HMIs do not support Koyo PLC protocol.
So, how would one go about configure a Harmony HMI to communicate to a Koyo PLC?

Resolution
Koyo PLC comm ports can be configured as a Modbus port. This would allow a Koyo PLC to be included on a Modbus network.

Koyo uses octal addressing. Attached is an Excel converter tool that converts the Koyo address to a corresponding Modbus address based on the Koyo Modbus port configuration.
