Hi,
has anyone tried to connect the widget designer with a siemens Logo over Modbus ? I would like to read Coils ( simple Digital Output) from the Logo in Widget designer. I had tried to set it up but found no Information about Data Type and right settings.
The Logo send the Output to Unit ID 255, Coil 3, Port 502. With other Modbus Tools i can read out the state of the output.
greetings
Marcel

Never worked with a siemens logo, but I did a lot of work with beckhoff Modbus Devices and WidgetDesigner
Modbus has different registers for types of inputs/outputs
digital outputs are normaly 0xxxx
digital inputs 1xxxx
analog outputs 3xxxx
analog inputs 4xxxx
Modbus Port is per default 502
Since I do know nearly nothing about Siemens Logo, can you explain Unit ID 255 and Coil 3?
How do you see the values in other Modbus Tools?
Feel free to contact me directly.
