I want to control the AC output 2 switch using modbus via Cerbo GX

I have a Cerbo GX and inverters set up and connected via LAN all working well, I’ve established Modbus communications and have all points and control of a generator all working well. The only point I cannot locate in the modbus register is the address for is the AC2 output relay to be able to control via modbus read/write. Can any one assist please

Cheers and thanks in advance.

So far the workaround has been to use the aux or temp programmed on the inverter itself in an assistant to drive the relay and then using a cerbo relay to drive the aux/temp.
Programming the relay on the cerbo with the parameters wanted.

I could be corrected (very happily) but as far as i know it is not open on the modbus
