I have two sets of code. The first one works just fine. but the second one does not. There is one difference in that there are multiple parameter's in the second code. My question is why does ignition update the UDT instances on the first code, but not the second?
first code(works fine):
"""Changes the Definintion's valuesource to OPC
• Fill in UDTFolderPath - This will change based on tag provider
"""
system.perspective.print("Process Started")
# import libraries
import csv
from datetime import datetime
# get our dates and time to put into file name
now = datetime.now()
now_str = now.strftime("%Y-%m-%d_%H%M")
# functions:
def createCSVOutPut(headers, dataSet, saveLocation):
""" create a dataSet with list, then make it a CSV file and save it to location provided
• Creates a CSV file based on headers and data provide to teh dataSet.
• headers and dataSet must be a list
"""
DataSet = system.dataset.toDataSet(headers, dataSet)
csv = system.dataset.toCSV(DataSet)
system.file.writeFile(saveLocation, csv)
# variables needed
configsCSVDict = {} # black Dict to keep CSV/Ignition info in - helps with faster processing times
totalCount = 0 # total tags looked at
tagUpdateCount = 0 # tags updated
dataSet = [] # empty list to create our CSV file

except KeyError as e:
dataSet.append([ignitionTagPath, "Key Error in CSV Dict", "Single Tag Component/has a tag name instead of UDT instance"])
break # Exit the inner loop and proceed to the next tagBrowse
# this was added due to the try except stopp the script from writing to the UDT parameter
if parameterValue != None:
UdtInstance['parameters']['L3'] = parameterValue
system.tag.configure(udtFolderPath, UdtInstance, 'm') # update tag properties
