The example program for S7-300 cannot be downloaded to the IM151-8 PN/DP CPU due to
memory requirements.
Note
Memory requirements of AS blocks
You can find the memory requirements of the AS blocks in the respective manual for
SIMATIC power rat e V4.0 S P2 with PC S
7 or WinCC.
Load management: Adhere to the order for configuring limit violations
To supply the messages with the correct, up-to-date associated values for load
management, pay attention to the data flow of load management in the implementation.
Program the blocks in the correct order of execution.
The "PRE_LMGM" block is called after the "PRE_SUM" or "PR3_SUM" block.
If the blocks are installed in different cyclic interrupt OBs (organization blocks), make sure
that at least one of the two conditions is met:
● You must install " PRE_ SUM" or "PR3_SUM" in the same cyclic interrupt OB as
"PRE_LMGM".
● "You must install PRE_SYNC" or "PR3_SYNC" directly before "PRE_SUM" or
"PR3_SUM" in the same cyclic interrupt OB.
