Limiting on-line connections to a S7-1500 PLC

2 posts in this topic

Hi,

I was wondering if there is a way to limit the number of allowed on-line connections at a time to a PLC?

Like can you somehow set in the PLC parameters that only 1 'connection' can be on-line in the device at a time?

Thanks

Edit: I'm referring to connections from the TIA portal - not HMI / ethernet connections and so forth

Hi Eriksn,

Yes you can limit the connections to PLC from PGs or any thing else;

Open the hardware configuration -> right click on your CPU -> select "object properties" -> select tab "communication" -> then you can set the number of allowed connections.
