Hi again, I actually just figured it out. I found a forum post elsewhere where a user had the same problem. There is a feature called "plug and play" in the Phoenix Contact I/O that must be turned off before writing outputs can occur. https://forums.ni.com/t5/LabVIEW/Modbus-Exception-Code-communication-with-an-Inline-bus-coupler/td-p/728227?profile.language=en

Hi, I'm having problems writing outputs over Modbus TCP. I will describe my setup first. Codesys V3.5 SP16 Raspberry Pi running Licensed Codesys 32-bit run-time Phoenix Contact Modbus TCP Bus Coupler 2703981 (IL ETH BK DI8 DO4 2TX-PAC) The Phoenix Contact Bus Coupler has one output card with 4 channels, and two output cards each with 4 channels. I have been able to write a Modbus Slave Channel to read the Inputs correctly and use them in a POU. I cannot figure out how to write to the output card...
