Hi all,

I have the same problem using PROFINET module rather than Modbus. No matter what I do with the bits (n+1).0 and (n+1).1 as instructed in the expansion module manual, tariff doesn't seem to change. However, I've left the .1 bit on for some time (by accident) and the tariff have changed.

I understand the unit is probably waiting for a full minute/hour or something similar, but couldn't find any explanation in either the manual for PAC3220 or the PROFINET expansion module. This is very unusual for Siemens not to explain the functionality. I can see the bit (n).4 does "Synchronisation of the demand period" but again, no explanation if that bit should be used together with the other two.

Since I'm not using Modbus, I can't access the register 917 mentioned above. Will I have to connect to modbus port just to change that on every unit?

Any help is more than welcome.

Thanks in advance.

Aleksandar
