Extrange License errors because of MODBUS blocks
Voted best answer
There was similar probelm on AKS some time ago (only that time it was F9.2):
It seems that the text You entered wasn't the couse of this error. Check if You have only one Modbus interface declared in Your system and if maybe there are Modbus blocks in two Process Stations resources.
Thank you very much for your answer MMM. It seems to me a question of limit of time for the license of MODBUS modules. Doing a check report of the installation the CBF was licensed 10/30/2003 (10 years ago) and the MODBUS blocks show just 1 license each. This was not truth until now, as the modbus modules have been working ok in 3 PS for 10 years! Could it be that the licenses for MODBUS blocks is only for 10 years?!!
I installed the CBF in another PC without the license key. With the 100 days grace period, I could plausibilize the project with no problem. Then I copied the project to the PC with key and send to the PS. Finally the simple modification was finished in this way. So, from now, it seems to me that I will have to make modifications in another PC with the grace period. Strange, is it not?
