Command groups of the SIWAREX WP321
Commands are forwarded from the FB_SIWA via data record DR 2 to the module
(scale commands, weighing commands, log commands). The meaning of the com‐
mands corresponds to the command list.
Reading of a data record, X corresponds to the data record number.
Example: Data record 3 transmitted by SIWAREX module to the SIMATIC CPU →
2000 + 3 = command code 2003
Writing of a data record, X corresponds to the data record number.
Example: Data record 3 transmitted by SIMATIC CPU to the SIWAREX module →
4000 + 3 = command code 4003
Read all data records from SIWAREX into CPU (only for SIMATIC FB)
Write all data records 3, 4, 5, 6, 10, 13, 14 and 15 from CPU into SIWAREX (module
must be in service mode, only for SIMATIC FB)
