S7 300 to Ignition

[bamfff 0]

Hi All,

This is my first project with Ignition so please bear with me. I'm setting up a system in which I'll be communicating a Siemens CPU 315 (CPU 1) with the existing CPU 314 (CPU 2) via MPI. The CPU 315 will be connected to the SCADA PC via Ethernet. I'll be using the tags from both of the CPU's. (see below picture for details)

My question is, will Ignition be able to see the tags in "CPU 2" even if it is not directly connected to the PC? If not, should I create a messaging program to transfer tag values to "CPU 1"?

Your help is much appreciated. Thanks a lot!

There is not gateway functionality in the Siemens controller so you will have to get the data from PLC1 into PLC 2.
