Configuring Register 37 (AC Power Setpoint) for Multi-plus II 8kVA

[runsurf252]

I am using a PLC to periodically ping register 37 (AC power setpoint) with 1.1kW over VE.bus as a test for my system. Using Cerbo GX to do so. However, I am receiving the following error in VRM.

On the PLC end, I am receiving error code 10 which I learned here means:

I am getting consistent data from the inverter via VictronConnect and my Cerbo is connected. I’ve also checked my unit ID and it is 227:

Running the inverter in “position I” with no load online, and the system is currently passing AC IN (230VAC) to the output while charging the batteries. I’ve seen a couple of posts related to this but have not reached a solution. Thanks for any help!
