Hello.

I have small issue on the TP1500 Comfort panels.
I Have project with CPU 1512SP ( new version: 6ES7 512-1DM03-0AB0) and 5 TP1500 Comfort panels.
The ethernet network is 100mb/s.
There are 12 profinet nodes for distributed I/O ET200SP.
Seems that the network works fine.

The Panel projects are prepared with TIA Portal V18 with all actual updates.
The firware was updated to V17 panel images ( latest ) .

And here comes the problem.

The operators are always in rush, so they put data on the panel, press start, and run to other activities.
Sommetimes after entering the new value on the panel it is shown in the I/O field for a second and retuns to the previous Value.
I have changed the seeting of the most important tags to be syncronized with PLC every 100ms, but it didnt solved the problem.

All the tags are set to be syncronized with PLC as "cyclic in operation" moust of them within 1s cycle. The information on the scales connected to the system and the recipe parameters set by operator are set to 100ms.

I tried i guess all the settings which comes to my mind to get proper data input.
Where to search the issue ?

Hello.

Thanks for reply.

Yes I have chcecked twice. 

The tags are only for Reading the values in the functions.

For example I have removed even the corection of the number of the recipe written by operator.

Before, when operator set the numer of the recipe outside permitted range system automatically corected the number. Now the operator can set any value he wants, the function olny gives alarm that it's out of range.

The issue is that,  lets Say, 49 Times everthing works fine, but 50th input Goes wrong. For a second we can see the proper value , and then it returns to orginal one. The operator usually do the double check, but late in night when they are in rush and tired , thay start to work like in "automatic" mode... they do new value=>enter=> start and the water goes in wrong temperature...

I don't know if it's important but also OPC serwer small is enabled on the cpu, but till nów we didn't comissioned the opc client.
