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]) |
