How can i remove/ identify this error "Value is not available because the limit for function tags was reached""

[Nicholaschew]

Dear All, i found this error during after finish HMI drawing. Is there anyone know the causing reason? All my tags is under Global scope.

I can't see the rest of your project, but it does look like you have quite a few custom controls defined.  There is also a limit on the number of retentive tags you can have, which can get consumed in a hurry if you have large data tables defined as retentive.

Please post your project or submit it to support@unitronics.com.

And Nicholas, please don't post the same question twice.  I've removed the identical one from the lounge but left a link there.

All posts on the forum are subject to moderator approval, so there will always be a delay in it appearing correctly.  It hasn't got lost and you don't need to do it again....just wait a bit...mods are worldwide.

I think you misundesrtood the custom controls use. 

You create a single custom control to all valves, other to all pumps, that share the same frame, buttons and layout.  Then, you place the control on the screen (or screens) you need it and set parameters associated with the device (pump, valve, ...) you want to operate.

Now i totally open a new project  and only draw a valve  , but still have the same issue. Is that possible i choose wrong PLC protocols communications? (From HMI communicate to PLC only)

Here you are using AV_001 as direct coil, it must be direct contact:

 

IP address is missing for remote slave1:

 

PLC is acting as Modbus TCP server or client? You set both modes up.

 

Active bits are missing in coils periodic task.
