Power Manager to S71200 Communication

Hi,

I am using Powermanager V3.4. I have a S7-1200 CPU 1214 DC/DC/Rly that has 78 Input and 74 Output that are used for Switchgear Control and Monitoring. I have to monitor the inputs and control the outputs from Powermanager but when I add a S7-1200 as Generic Modbus Device as mentioned in manual i can only access 10 Inputs and 10 Outputs.

Is  there any way that i can access more I/Os in Powermanager through a single S7-1200?
