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.
