M340 read MODBUS device value

[Anonymous user]

Hi all,

I'm new to Schneider PLC. I had try some READ VAR tutorial but I couldn't get the data. There are few uncertainty in my mind. 

1. When I using M340 with P342020 what is the ethernet and modbus VP 5V5 r.m.c? 0.1.x

2. when I add network for ethernet it is unable to build.

3. What is the code error means for array check[2]?

I not sure what I miss out when configuring.

Early thanks for read and help in my problem.

your syntax for ADDM is not quite right, you have to use '0.0.3{IP Address}Tcp.mbs'. make sure Data variable array size is the same as NB, see the pictures attached.

Hello Anonymous,

1: r.m.c. = Rack, Module, Channel. The ethernet port of the CPU is 0.0.3

2: What's the error message in the output window?

3: Check manual https://www.se.com/nl/nl/download/document/33002527K01000/ page 42/43: 16#10 (=16 decimal) = Network module missing (probable cause is the address r.c.w. 0.1.2)

Also please set the check[4] to a defined value (>0) like 10 = timeout = 1 second). See above manual page 45
