Modul Library for Simatic S7

of ifaut engineering Dresden / Germany



In order for the blocks of the PLCmodules library to be processed in a real PLC CPU, it is necessary to enter a special runtime license in the DB2 data block of the project.

Without a correct license, the CPU will immediately switch to the STOP state!

Each license is linked directly to the unique serial number of the MMC memory card or the CPU. However, this serial number is only needed to unlock the license. If the serial number is not known, it can be read using the program "SN_TEST" which is available in the software download area.

Expiration of licensing:
