8.3.2 With tare warning
The DIGIFORCE
®
9311 can generate a warning if the sensor signal to be tared exceeds a configurable
threshold value. You can enable and set this threshold in the "Channel settings" menu (M21) (for further
details, please see section 6.3.1 "Channel settings" on page 71).
Diagram 95: With tare warning
*You can define a configurable PLC output for the signal "OUT_WARNING_TARE".
Cycle
a. The PLC first checks whether the instrument is ready, i.e. if "OUT_READY" = 1.
b. The PLC initiates the tare procedure with "IN_TARE_Y" = 1.
c. The DIGIFORCE
®
9311 then resets "OUT_READY" to 0.
d. If the live sensor signal exceeds the set warning limit, the DIGIFORCE
®
9311 sets the
output "OUT_WARNING_TARE".
e. On detecting "OUT_READY" = 0, the PLC can use "IN_TARE_Y" to stop the tare
process.
f. At the end of the cycle, the DIGIFORCE
®
9311 sets "OUT_READY" to 1 (in standby).
The PLC can now evaluate the "OUT_WARNING_TARE" warning output signal.
Note:
The warning is withdrawn if the warning condition was no longer met in another tare process, or
if “Tare” has been disabled.
