Hi justantyme, 1. Are you sure that this HMI can connect to the plc? i.e. is there a melsec driver. 2. Are you using the correct interface. It is very easy to confuse RS232 w/ RS485 connections. If you have layout of the Hitech hmi's pins, we can assist by providing the FX's pin layout. WayneS

Your hmi is connected directly to the prog. port of plc? Which type of message you see on your hmi? The cable is too long? Have you contacted the hitech company? Try also to connect to other Fx plc. I don't know hitech hmi but are you sure the driver you have installed provides the communication with FX2N cpu? On your softw. developm. you can see the choiche FX2N ? bye Max
