Hello,
I have the following Gateway Tag Change Script on a tag “Counter”:
‘’’ if not initialChange:
currentValue = event.getCurrentValue().getValue()
previousValue = event.getPreviousValue().getValue()
if previousValue > currentValue or currentValue == 0:
sc = system.tag.readBlocking(["[default]UNI_Room12/StartCount12"])[0].value
brb = system.tag.readBlocking(["[default]UNI_Room12/BatchResetBit12"])[0].value
pv = system.tag.readBlocking(["[default]UNI_Room12/PreviousBatchCount12"])[0].value
pv = pv + previousValue
tagPaths = ['[default]/PreviousBatchCount', '[default]/BatchResetBit']
values = [pv, brb+1]
system.tag.writeBlocking(tagPaths,values)
if currentValue > previousValue or previousValue == currentValue:
sc = system.tag.readBlocking(["[default]UNI_Room12/StartCount12"])[0].value
cc = system.tag.readBlocking(["[default]UNI_Room12/Counter"])[0].value
pv = system.tag.readBlocking(["[default]UNI_Room12/PreviousBatchCount12"])[0].value
total = pv - sc + cc
system.tag.writeBlocking(["[default]Total"],[total])'''
The script works well, however randomly I have the following problem:
as you can see on the attachment, though the previous value of the counter (65292) is not greater than the current value (66848), the value of the brb variable goes from 0 to 1, i.e. the first part of the script was executed. Any idea why?
