PKC controllers Modbus connectivit


We have in project PKC 111172300 controllers 14 pcs.
We would want to connect those in Modbus and read values from controllers by WinCC Scada system:
Values like:
- The set target value
- actual measured value
- alarm output actual value (ON/OFF)

What are the tags/addresses for these value?
Do you have any samples about systems where Modbus connection for the controllers is used in similar way?

The Modbus connections, when all 14 controllers are connected together, does it need an end resistor? If it requires an end resistor, how many Ohms?

Something else relevant, please share?
