FINS Ethernet in CPL1-EL

[NgoHoang 0]

Dear all!

I'm studying a case as follow: Use a tool on PC (Hercules) Write value 1234 (0x04D2) to D10 of PLC CP1L-EL via FINS Ethernet UDP with built-in Ethernet port.

1. Config on PLC and PC (Hercules tool) in attach files.

2. IP PLC: 192.168.3.111, IP PC: 192.168.3.123

3. Send command from PC (hex): 46 49 4E 53 00 00 00 1A 80 00 00 01 FA 00 00 00 00 00 00 00 01 02 01 01 82 00 0A 04 D2

   + 46 49 4E 53: 'FINS' header.

   + 00 00 00 1A: data length 26 bytes.
   + 80 00: Identify FINS UDP.
   + 00: Network Address.
   + 01: Node Address of PLC.
   + FA: Unit Address of Ethernet build-in Port on PLC.
   + 00 00 00 00 00 00 00 00: Set to 0.
   + 01 02: Write command.
   + 01 01: Sub-command.
   + 82: Memory code for D area memory.
   + 00 0A: Start address (D10).
   + 04 D2: Value need to write (1234).

=> Dada CAN NOT Write to D10 of PLC.

=> Could you help to suggest to me what is wrong or miss?

=> Do need to put SEND, RECEIVE or CMND instruction to source-code?

Is the PLC in Monitor mode?

It seems like you understand FINS but if you would like, here is a tool that may be useful. I haven't used it in quite some time.

Nice!

There are FINS commands to Read and Write the PLC Mode. (RUN, MON, PRG). This can be helpful if CX Programmer is not available.
