SENTRON PAC3200 and CompactLogix

Hello, guys.
I have a SENTRON PAC3200 connected to CompactLogix L30ER. It has an IP address, it's set to Modbus TCP and now I need to read some values from it. Problem is - I have zero experience with SENTRON and the same amount with Modbus, so I need some pointers how to read for example voltage or current.
Any suggestion, like manual, or step-by-step instruction or program sample?
Thanks in advance.

Here is the manual for the Sentron PAC3200. 3.9.2 Modbus TCP
This will list the addresses needed to read the information and the format that they are in.

The above are links for L30ER Modbus TCP.

Here is a great introduction to Modbus TCP.

I hope this helps you out.

Many thanks, got the sample code from RA site, imported it into the program and now I can read something. Not sure what exactly yet because of different data format, but that's already no big deal.

Hi,
and it will be useful having readily available a small manual with software https://www.virtual-serial-port.org/...odbus-scanner/ . Also informative. All the same monitoring helps in many situations and without it in any way.
