Re: MODBUS TCP IP IN CONTROLLOGIX
Hi
If you download the sample code, there are 2 manuals on the zip where you can read that the code only accept a maximum of 4 connections to unique IP address.
However, the manual also says that you can change this limitation modifyng the application (possibly on the tags).
Good luck!
