Hello,
Trying to connect controller R-30iB and PC with Modbus. But my controller is not available now, so I use roboguide as virtual controller.
After reading Modbus TCP Interface Operator's manual, I still have lots of questions.
What's the slave ID (device ID) of controller? Can I modify it?
What's the address with function "Read Holding Registers" for master polling?
Currently the Modbus IO of controller is DO[129-192], DI[129-192], as what I read from manual, the address is supposed to be 10008 but the polling is failed.
Other information:
The connection is successfully built.
Running roboguide and Modbus master at same PC.
Tested on two PCs that are Windows 10 and Windows 7.
Use Modbus Master Tool from Witte Software for testing.
Use roboguide version 9.
