Looking on M2M specification, there are different models, most of them with Modbus RTU, one with Modbus TCP/IP and one with Profibus. Also one type is without a protocol.

What is your type of device?

What do you need to read?

You can use all the tree protocols with PM573-ETH, Modbus RTU trough integrated COM port in AC500, Modbus TCP/IP trough integrated Ethernet port of AC500, for Profibus you will need additional Profibus module to the CPU. Also there are some analog, digital and pulse outputs of M2M, but I think that is not your case.

I can recommend Modbus TCP/IP or Modbus RTU (without a need of additional hardware) - it depends on the type of M2M.

This is from an old project which I had done.For an experienced Engineer this info is more than sufficient to develop the PLC program for communicating with the device whose data sheet I have attached.In case you are talking about how to set the comm parameters on the MFM,then I can share with you another manual I referred to.
