OTB I/O and Twidosoft

[kdw electric 0]

Can anyone let me know how to configure an OTB I/O block on Modbus from a Twido plc. I've tried both TwidoSuite and Twidosoft. Neither will let me choose the OTB macro block.

you need the .MDF file for OTB Macro otherwise........ Anyway Modbus protocol is modbus protocol for any equipment using modbus protocol!!!! So you can use macro Comm without problem or you could write by yourself the List : it's a good exercise for understanding modbus protocol and how to program it. All macro for modbus are practically the same because modbus is modbus! configure the instance 0 of Comm macro. Set the modbus address of OTB, the modbus port of twido, after that choose how many words you need to read / write and clic to creat symbols. Go in the program List, load the ADDR word just created and set the start address, then call the macro instance
