Enabling S7-1200 for MODBUS TCP

I'm using Archie's AdvancedHMI to attempt to read data from a Siemens PLC S7-1200 (MODBUS TCP) to run a stored procedure and I will take that result and put it back in the PLC.
The integrator working with the PLC is having trouble finding out how to enable/configure the MODBUS TCP in the S7.
I am basically going to read a bit (trigger) from him, then a string value, and I will return an integer back to him.

Could someone shed some light on how to enable this on the S7? I don't really work with Siemens products.

Thanks!

There are instructions for Modbus in the 1200.
The system manual or this example should help.

Thanks, I'll pass this one along, although it looks familiar as I think he might have already referenced this one. Maybe it's time for me to learn Siemens.
