Writing I&M Records
I&M data can be written using the standard WDREC (SFB53) function block in the TIA portal.
First, the hardware identifier of the CPU is read out under "PLC Variables > System Constants."
The CPU should be displayed there as <Local> with the data type "Hw_SubModule." You spec-
ify the hardware identifier via the corresponding input parameter (ID). The I&M index (INDEX)
and the data length (LEN) to be written must also be transmitted. The return parameters con-
tain a status or an error message.

Prioritized Start-Up/Fast Start-Up (FSU)
The modules with Fast Start-Up (FSU) support optimized system power-up. This ensures a
quick restart after a power supply is restored after an interruption.
