Ethernet IP - Multiple Outstations, Single IP Address

[bwill1177]

I am attempting to set up multiple Ethernet IP outstations (AB logix processors) on a single IP address but at different slot locations.  I've tried to set this up but can only get one Outstation to communicate at a time.  I'm wondering if I am not setting this up correctly or if this functionality is impossible with GeoSCADA.

Thanks.

This sounds like a known issue (CSUP-12891) that was fixed in the May 2022 monthly release of Geo SCADA, see the release notes for more details.

Thanks for the reply. 

I was able to finally upgrade to the release that claims to address this issue, but I am still unable to connect to multiple processors in different slots, via the same IP address.  When I double-check the release notes it seems to indicate that the port number must be unique.  Doesn't Ethernet IP only use a single port for TCP (44818)?  How am I supposed to use a unique port?  It seems that a better solution would have been to include the slot number as the unique identifier.

[CSUP-12891] EtherNet/IP driver: We now include the port number of the outstation's
address when checking for unique network addresses. This allows multiple EtherNet/IP
outstations to be configured with the same IP address, if their port numbers are unique.

The fix for CSUP-12891 changed the unique identifier from IP address and slot number to IP address, port number and slot number. The customer who reported that issue was using a router with port forwarding, which is why they had different ports.

In this same issue it was reported that they could only communicates with one outstation at a time and this was also fixed, but this isn't mentioned in the release notes.

I would suggest raising this issue with customer support.
