Hello,Â
For a Motion controller application, we will have 10 HMIs connected to an MLC Controller (up to 12 following the configurations).
the HMIs will be WR21 (7" and 15"), the maximum amount for tags are around 1000 tags (~100 per HMI),Â
my questions are :Â
- is it possibe to configure and licence 15 webClients into 1 WebIQ Server.
- is yes, a ctrlx Core (used only as WebIQ Server) is enough to manage them ? or do we have to consider an IPC Based server ?Â

Sure you can have 15 clients or more connect to a single WebIQ Server instance.
When it comes to WebIQ there would be no issue connecting to 12 OPC-UA data sources and using 1000 tags.
However, this cannot be a simple yes or no reply, because it's completely based on how you implement your HMI and what your requirements are. In theory you could:
- have 1000 tags displayed on a single HMI view (i.e. browser window) at the same time with all tags updated (changed!) every 100ms (the main issue here would probably be the graphics adapter on the display and the network latency)
- have around 50 tags displayed on a single HMI view (i.e. browser window) at the same time that update every few seconds
- or recording 1000 tags every second vs. recording 100 tags every 30 seconds
These are not any limits or problematic for WebIQ - I just used them as arbitrary examples.
Therefore our (WebIQ) recommendation is always to try it out - actually depending on how you implement an HMI you can cause more or less load on the system by splitting up the display into sub-views for example.
