The PyPLC is an attribute mapping layer on top of Modbus C++ device server.

Have you been able to configure the Modbus device?

Once you configured it, try if any of these calls returns any value:

ds = PyTango.DeviceProxy(‘your/modbus/device’)
ds.ReadHoldingRegisters([0,10])
ds.ReadInputRegisters([0,10])
