Event Script (Client) Error

Ignition
1

Hello,

My post has 2 questions:

[size=150]1)[/size] I am running a tag change script on the Client:

[code]from java.util import Date
dateFrom = Date()
dateTo = Date()

dateFrom.setSeconds(dateFrom.getSeconds()-2)
dateFrom = system.db.dateFormat(dateFrom,“yyyy-MM-dd HH:mm:ss”)
dateTo.setSeconds(dateTo.getSeconds()+2)
dateTo = system.db.dateFormat(dateTo,“yyyy-MM-dd HH:mm:ss”)

value = newValue.value
pathString = event.tagPath
username = system.tag.getTagValue("[]Line01/currentPLCUser")

#print “UPDATE alarms SET ACK_USER = ‘%s’ WHERE (ACK_TIMESTAMP BETWEEN ‘%s’ AND ‘%s’) AND PATH LIKE ‘%s’” % (username, dateFrom, dateTo, pathString)
if value == 0:
system.db.runPrepUpdate(“UPDATE alarms SET ACK_USER = ? WHERE (ACK_TIMESTAMP BETWEEN ? AND ?) AND PATH LIKE ?”, [username, dateFrom, dateTo, pathString ])[/code]

and i get the following error:

[code]ERROR [TagChangeScriptManager-TagChangeScript: Line01/SGM/Alarms/RTD/spreader_box_left_rtd] Error executing tag change script: Line01/SGM/Alarms/RTD/spreader_box_left_rtd

[/code]

Any ideas why? the SQL statement that i print is correct because i ran it in the MySQL db

[size=150]2)[/size] Why can’t i use this script in the Event Scripts (Gateway)? It seems it never runs, but in Client works fine:

Hi,

For the error, it looks like it’s sending an actual tagpath object that only exists in the client to the gateway, instead of the string. Try this:

if value == 0: system.db.runPrepUpdate("UPDATE alarms SET ACK_USER = ? WHERE (ACK_TIMESTAMP BETWEEN ? AND ?) AND PATH LIKE ?", [username, dateFrom, dateTo, str(pathString) ])
(It’s the same as yours, with ‘pathString’ wrapped in a string cast)

For #2, not sure- it should work. Try adding a print statement, and then look for it in the gateway console. And of course, these scripts only take hold when the project is saved.

Regards,
