HMI client count wrong?

Hi, today I was surprised by the fact that even though I had 2 computers connected to the HMI of a F2152, the controller showed CLIENT_COUNT = 1 in HMI_STATUS and the IP address of CLIENTS[1] was swapping the last octet (one address is 12, the other 21, but these are 2 different machines). My expectation was that if there are 2 computers connected there should be 2 (independent) sessions and client_count should be 2 too. That’s not really a problem now for us, but I can’t use client_count to control the number of concurrent sessions. kind regards, frank

Hi Frank, The accepted answer to the second part of this question is relevant, I think: https://www.plcnext-community.net/en/?option=com_easydiscuss&view;=post&id;=5025 Hope this helps. ~ Martin.

Hi Martin,

I think the link is broken. I have the same issue, I’ve managed to increase the client count by adding different Station ID in the URL as explained in the help docs (https://engineer.plcnext.help/2023.0_LTS_en/_index.htm?iframe=https://engineer.plcnext.help/2023.0_LTS_en/HMI_Visualization_Run.htm)
But I think this should be done automatically, when different users log in the HMI application.

Kind regards,
Juan

Sorry about the broken link, a site upgrade a while back broke lots of old forum posts.

This is the discussion that I was referring to:
Forum - PLCnext Community PLCnext Technology from Phoenix Contact is a unique, open ecosystem for modern automation that is capable of meeting all the challenges of the IoT world. It looks like you’ve found the same information in the PLCnext Engineer help system.
Thanks for the feedback. I will pass on your comments to the developers.
