Parameter assignment in the user program
You have already set the parameters for the S7–300 module using STEP 7. You can use an SFC in the user program to
change the AI 6 x TC module dynamic parameters. You can also use an SFC in the user program to transfer the parameters
from the CPU to the addressed module.
Parameters stored in data records
The parameters for the AI 6 x TC module are stored in three data records: records 0, 1 and 128.
Modifiable parameters
You can change the parameters of record 1 and/or record 128 and pass them to the AI 6 x TC module using SFC 55. This
does not change the parameters set on the CPU. You cannot change the S7–300 parameters of record 0 in the user
program.
The following section shows an overview of the parameters that are stored in records 0, 1, and 128 for the AI 6 x TC module.
SFCs for parameter assignment
The following SFCs are available for assigning the parameters for the AI 6 x TC module in the user program.
SFC NO. Identifier Application
55 WR_PARM Transfer modifable parameters (record 1 and 128) to the addressed signal module.
56 WR_DPARM Transfer parameters (records 0, 1 or 128) from the CPU to the addressed signal
module.
57 PARM_MOD Transfer all parameters (records 0,1, and 128) from the CPU to the addressed signal
module.
Description of the parameters
The following section contains all the modifiable parameters for the AI 6 x TC module.
The parameters for the AI 6 x TC module are described in this Product Information document and in the online help of
STEP 7.
