Hi,
first of all, thanks for your reply. In our case, that wouldn’t be a problem, because our CPU is Siemens 317-2 PN/DP with 32 socket connections available. Currently, we have connected the following devices:
- 4 HMIs (through PROFIBUS)
- Ignition gateway (through Ethernet)
The problem appears when we connect another device through Ethernet (our PC with Siemens Step 7 to maintenance and programming tasks).
In our CPU configuration, we have 6 reserved channels for HMI connections, and 4 free additional channels for programming. In fact, we have 12 reserved channels for Ignition Gateway (we have tried testing with more and less channels in order to get a solution, but problems continue).
Thanks a lot
Best regards
