Thanks for reply, Crossbow. But in this case I don't understand what is wrong. GOT messages "Communication error" and doesn't connect to PLC, though communication driver (MELSEC-FX) is installed in GOT, assigned to RS-422 interface and all settings seems ok. And also I don't have a communication with PLC from GX IEC Developer (PC is connected through GOT). It looks like something is wrong but I don't understand what...

Dear All, I have to connect GOT panel (GOT1155) to the FX1N PLC, but I don't have a cable (GT01-C10R4-8P) and can't wait until it will be delivered from somewhere. Probably somebody has a wiring diagram for this cable? Before we used GOT900 serie, and now it looks like cables for these series are different. Thanks in advance.

Thanks, Crossbow. I've read all manuals carefully one more time and now it seems everything is clear for me. Sorry if I asked stupid questions but it's human nature to ask before follow the principle RTFM.

Dear Crossbow, thank you for your reply. Of course, you suggested the best solution, but unfortunately not everything depends on me. My boss prefer to save money, but not my time. So I have to do it with existing controller... Another question. I found one program example at mitsubishi-automation.com (ModbMFX) with corresponding function block, but I'm not sure is it suitable for invertors or not. At the moment I don't have invertors on site and can't check it. Can smb. advise me anything? Thanks in advance. Alexey.

Dear All, I have one question. I have to connect FX1N PLC and 10 LG IC5 invertors via RS-485 with Modbus RTU protocol to send frequency parameters (start/stop will be done by external signal). As I understand, I have to write this protocol manually in the PLC program. I have some examples with Mitsubishi FR-S invertors control, but there is different protocol and at the moment I don't know how to solve this task. Probably, somebody could give me an example of the program with Modbus RTU data transmission? Or at least explain how to make it? I would appreciate any help. Thanks in advance for reply. Alexey.

Sorry, but I'm not completely agree with vaibhav about PCMCI adaptors. Couple months ago I tried to use such adaptor and with GX IEC Developer it worked fine, but it didn't work with GT Designer, so I was unable to download project to the GOT panel.
