ethernet comunication problem (sockets)

[ericj 0]

Hi, I am trying to make an ethernet network between my computer, CJM1 PLC with CJ1W-ENT21 and an FZ (vision sensor) using sockets. I want to use this connection to transfer data: bools and words from the vision sensor to the plc. Now it seems I can't open the tcp/ip connection (on the plc no tcp light is on). I have the program and the settings of the camera attached to this thread. I use he plc as server and the camera as client so I tried to open the passive port in the plc. Do I write the IP address of the client somewhere in the plc? As far as I know the IP address and memory addresses are ok I hope someone can help me with this. Thank you in advance!

Check myomron.com (register), go to downloads/8.Programming Samples/PLCs/Function Blocks (Beta Release), there you find FB Modbus TCP.zip. It is a function block with some documentation to use a function block for setting up a Modus TCP client in a ETN21 unit. It works pretty wel. Socket Communication With CJ1W-ETN21 Nevermind, I thought you were talking Modbus TCP to your camera judging the file name of your program but it looks they are just raw socket data.
