Hello,
1st of all I'm a newbie and I'm programming WAGO 750-843 using codesys 2.3 to communicate with 3 slaves (Schneider Power meters) and, I'm used to doing this by Modbus network configurator AND 750-881 CPU, somehow it's easy, but with 750-843, Modbus network configurator won't do the job, I don't know why the serial interface is in standstill nothing is going to or from it, and I want to communicate with those power meters manually using some functional blocks I searched on the web and I found modb05.lib library, it contains some functional block such as extended slave which is the one that I think will do the job,
If anyone has an example or could help by any mean, I would be so grateful,
thanks in advance.

thanks for your reply this site contains libraries and this is where I downloaded the mod05lib and there is some information about Modbus functional blocks,
if there is an example of how to read data from more than one slave or at least
what functonal block should I use I would be thankful .
