GT2104-RTBD HMI and FX3GC-MT/D PLC

[mitryan]

Hi, Hopefully someone can help me, i have a FX3GC-MT/D PLC originally connected to the GOT1000 HMI using RS422/RS485 connection, we replaced the HMI with GT2104-RTBD GOT2000 series, using the same cable (mini din 8) but then my PLC and HMI isn't communicating. Attached is the screenshot of my HMI communication setting and PLC parameter setting. Im guessing due to communication wire used but i don't have access to the pinout of the PLC. Hoping for some input. Thank you.

Non procedureal can't be right !!! but also not for a Got 1000.

Are you sure you are suing channel 1 or are you connected to the programming port ?

I have no idea about the non-procedural thing, i just downloaded the program and parameter from the PLC. Channel 1 is the controller setting on the GT Designer 3.

With Channel one. I mean the CH 1 of your GX works project which is set to non procedural.
Is the GOT connected to PLC programming port?

 GOT is connected to the PLC via the RS422 (mini din 8).

Following the connection i gather standard pinout layout for mini din8:

1. Black (Input Handshake/Ext close)

2. Brown (Output Handshake)

3. Red (Receive Data V-)

4. Orange (Ground)

5. Yellow (Transmit Data V-)

6. Green (Receive Data V+)

7. Blue (No Connection)

8. Violet (Transmit Data V+)

basically i connected the the RDA&RDB of HMI to the Receive of PLC and vice versa.

Are you using a GT10-CxxR4-8P  Cable ?

No i am not using the said cable yet but it is already for delivery, i'm just trying to find the correct pinout of the FX2GC mini din 8pin port as it seam to be different from standard pinout. Anyway thanks for the input.
