Weighing Functions
5.6.5
DR 7 - Process value 2 for fast output to the SIMATIC CPU
Process value 2 can be defined just the same as process value 1 (see above).
In automatic scale operation, the current AWI status (Selection number 30) is
normally important.
5.6.6
DR 7 - Definition of the process alarms 0, 1, 2, 3, 4, 5, 6, 7
The process alarms can be defined with this parameter. The module can generate
process alarms in the SIMATIC CPU. The control program can react immediately
to an event this way. Defining a process alarm is explained with the example of
process alarm 0. The explanation applies for process alarms 1 to 7 as well.
If parameter value 0 is defined for process alarm 0 then no process alarms are
generated.
By entering a value unequal to zero, a process alarm is allocated according to the
following procedures:
Value range 1 to 255
Number of the technology message. If the defined technology error occurs then
process alarm 0 is generated.
Value range 256 to 319
Number of the bit from the NAWI- or AWI status (see DR 30). If the defined status
occurs then process alarm 0 is generated.
256+ 0... 31 Bit-No. NAWI Status bit - coming
288+ 0... 31 Bit-No. AWI Status bit - coming
Value range 512 to 575
Number of the bit from the NAWI- or AWI status (see DR 30). If the defined status
goes then process alarm 0 is generated.
512+ 0... 31 Bit-No. NAWI Status bit - going
544+ 0... 31 Bit-No. AWI Status bit - going
5.6.7
DR 7 - S7-FB-Life bit Monitoring Time
By monitoring a life bit, the SIWAREX FTA can determine whether the FB is
ensuring continuous communication with the SIMATIC CPU. If the FB does not
respond then an operating error is output after the defined time-span has elapsed.
Monitoring is active in SIMATIC_CPU RUN status.
