Deybid Castillo Posted June 23, 2019 Report Share Posted June 23, 2019 Hello, my name is deybid, I am looking for a little help with this plc unitronics and this hmi delta brand, since it is the first time that I am going to work with these equipments and I would like to have a modbus communication, since it is the only option that It gives the hmi delta software but I can not get the communication through the plc cable rj11 -> rs232. I have been investigating the program that I have to load in the PLC since I want to work as a slave, but even so I do not have much knowledge about this equipment. I would appreciate it if you would help me. Thank you and I'm sorry for him. English. Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted June 25, 2019 MVP 2023 Report Share Posted June 25, 2019 That cable you have pictured does not work for modbus 485. You need to have a cable that connects to terminals 1 & 6 on the com port, and also have some physical jumpers set properly. This is fully explained in the manuals for a V130. And initially drop your speed to 9600 until you get it working, then adjust if the system can tolerate it. cheers, Aus Link to comment Share on other sites More sharing options...
