Issues regarding communication between PLC and Delta touchscreens
Thread Content
PLC: The communication port of the FX1N is RS422. Touch screen: RS232. So, I was wondering if there is a data cable that converts an 8-pin circular RS422 interface into an RS232 serial interface? Could you tell me the model?
First, you need to determine which communication protocol will be used to enable proper communication between the HMI and the PLC. Then, you must establish the physical connection. 422 and 232 are two different serial communication standards, so they cannot be used; it is necessary to convert them to a unified standard
Aren’t there any data cables available on the market that convert RS232 D-type 9-pin connectors to RS422 round 8-pin connectors?
So, how can I communicate between a Delta touch screen and the Mitsubishi FX series?
First, check which Mitsubishi protocols your Delta touch screen supports, and read the manual carefully
RS232 has 3 wires, RS422 has 4 wires. How to connect them? A converter is needed to standardize the physical connection, either 232 or 422
There should be such a data cable. I have one here that can be used for communication; I use it to connect a Delta touch screen (DOP-B07S515) with a Mitsubishi FX1N-60MR. However, I don’t know how to describe its model.
