By using the SFCs 55, 56 and 57 you may change the parameters of the
analog modules during runtime via the CPU. The time needed until the new
parameterization is valid can last up to a few ms. During this time the
measuring value 7FFFh is issued.
The following example shows the assignment of record set 1 to the module
331-7Kx01 during run time.
Record set 1 from module 331-7Kx01:
Byte Bit 7 ... Bit 0
0 Bit 5 ... 0: reserved
Bit 6: Diag. interrupt release
Bit 7: Proc. interrupt release
1 Interference freq.suppression
Bit 0,1: Channel 0/1
Bit 2,3: Channel 2/3
Bit 4,5: Channel 4/5
Bit 6,7: Channel 6/7
2 Mode Channel 0/1
Bit 3 ... 0: Measuring range
Bit 7 ... 4: Measuring type
3 Mode Channel 2/3
Bit 3 ... 0: Measuring range
Bit 7 ... 4: Measuring type
4 Mode Channel 4/5
Bit 3 ... 0: Measuring range
Bit 7 ... 4: Measuring type
5 Mode Channel 6/7
Bit 3 ... 0: Measuring range
Bit 7 ... 4: Measuring type
6, 7 Upper limit value Channel 0
8, 9 Lower limit value Channel 0
10, 11 Upper limit value Channel 2

Transfer with SFC 55 "WR_PARM" Record set 1to Module:
Call "WR_PARM" //call SFC 55
REQ :=TRUE //write request
IOID :=B#16#54 //identifier for the address space: peripheral input
LADDR :=W#16#100 //logical base address: 100
RECNUM :=B#16#1 //record number 1
RECORD :=#rec1 //record for Record set 1
RET_VAL :=#retval //return value (0: no error >0: error code)
BUSY :=#busy //
