Function
Restriction of the fault-tolerant CPU
Use of SFC 49 "LGC_GADR"
You are operating an S7-400H automation system in redundant
mode. If you declare the logical address of module of the switched
DP slave at the LADDR parameter and call SFC 49, the high byte
of the RACK parameter returns the DP master system ID of the
active channel. If there is no active channel, the function outputs
the ID of the DP master system belonging to the master CPU.
Call of SFC 51 "RDSYSST" with
SSL_ID=W#16#xy91
The data records of the SSL partial lists shown below cannot be
read with SFC 51 "RDSYSST":
SSL_ID=W#16#0091
SSL_ID=W#16#0191
SSL_ID=W#16#0291
SSL_ID=W#16#0391
