1756 eweb - chart script

DanWard · Dec 27, 2006

I am trying to write a script for a 1756 eweb to chart downtime with a time stamp, I am trying to log daily downtime on a power chain. I need the chart to show a 8+ hour run.Is anyone doing anything like this...?

The EWEB can't execute scripts based off of events. A PC would have to poll the EWEB to do this or the Controllogix would have to log the data for later viewing. I would prefer the second method.

Either is do able. Which way you want to go?

Thanks, I got with a networking guy who wrote me a script. im not executing based off events, im using a server side script and viewing a log.asp file in xml. it views as a chart recorder showing me two states with a time stamp. Im not sure how it all works im not into java or xml, I write code. I did not have to do anything with code. I gave him the address and tag and he gave me the script, I ftp the script to the eweb card and all works great... Thanks.

I spoke with a AB tech support, after speaking with several techs I finaly got someone who knows the card well, the eweb card is a server, and with proper scripting will execute scripts based off events. Ab does not support java. but they do offer a server side tool kit that helps if you dont know java. you really need someone who can write java code.

Glad you got it worked out. What do you think of the EWEB?

I like it, I use it so all of our managers can monitor floor production numbers in their office at the click of a mouse. its that or print a crystal report, I have about 20 pages on it, it emails downtime reports and trends. I am reading tags from about 50 plc's both ethernet and DH+. CONS-the more you give the ops managers the more they want..PROS-keeps them off the floor...

Yes the more you get the more they want

But don't forget about maintenance. If you have a wireless network you can use the EWEB with Wireless Palm Pilots for diagnostics instead of having to run and get the laptop

I wish wireless, cant get them to spend the money..
