OK! Now is the time to explain how to make a PLC program that can use non-protocol communication to exchange the data between other devices. I will not explain so much on what is Data Length,Parity Bit…Something like this, please check inside the Wiki or MR Google ). Navigation Window ->Parameter -> FX5UCPU -> Module Parameter ->485 Serial Port Termination resistorįor One-Pair wiring, please push theTermination resistor selector switch to 110 ohm.įor Two-Pair wiring, please push theTermination resistor selector switch to 330 ohm. *the wiring will effect the Termination resistor setting and communication setting inside the GXWorks project, I will explain these stuffs on the below. In RS485 there are One-pair wiring and Two pair wiring, and in this application, the devices is only support one-pair wiring. *Be honestly, GXWorks3 is not a good item…. Serial Communication by Wiki system configurationīecause the CPU that i am using here is FX5U, only GXWorks3 is available. It is a communication method that used to exchange the data between printer,bar code reader.Etc. Hi, this topic is a basic instruction and wrote some memo in here while i using Mistsubishi FX5U application of RS485 interface control.Why i write this? because in the manual there is not so many details and example about these information (… Non-Protocol Communicationįirstly, What is non-protocol communication?
