I've never used the web server in a ML, but this manual may be of some use: http://forums.mrplc.com/index.php?app=downloads&showfile=495 It's for a ML1100, but I assume they are similar.

If quality and ease of use were factors I recommend OSI soft's PI historian but they are not cheap....you get what you pay for.

Ask your rep. for the price of the lowest support, I do not recall the exact name, something like econnect. Should be way cheaper than the software upgrade, then you can download the latest version at no charge.

I do not recall how many high speed inputs the ML1100 has, but another options would be to mount a prox switch so that motor or pump rpm could be monitored. A simple collar with one pin and a prox switch, count the pulses to determine RPM, you do not have to be extremely accurate, since you are basically looking for a run/no run status. Just a thought.

I used to work at a Plant that had several installations of Fix 32, the upgrade path is a little murky. GE does not give the same level of support that Intellution gave. I recommend you keep good backups.

The type of book you are describing would be classified as "Hard" science fiction, I'm sure a google search would turn up many good suggestions. regards, Ken

I have to admit that I almost never call support, maybe once a year. I would like to have a different line to call. The I know what I'm doing line. You would have to pass a test to get access. Then I could bypass all the simple questions and jump to the meat of the problem. Just saying.

Hey Okie, I have the same problem as the guy in the link. I called RedLion this morining and they said it was a hardware issue, and should still be under warranty. It's a 306A, not a 308, I have two 310's in service for about a year longer and never had any issues. The other link was a 306 too, wonder if there is a model specific issue? thanks, Ken

I have a 308 that has been in service 18-24 months, two days ago the display stopped working. I can ping it, and I can "see" the display via the web server. So I assume a back light or fuse or something has blown, are there any user replaceable parts? I plan on calling Red Lion later, but I suspect I will have to replace it. thanks, Ken

I always use black/red or clear/black and black is ALWAYS negative. Just like your car.

Well.... how would a human do it. I would open 100% and wait until it felt warmer then throttle back. What happens if you open control valve 100% in manual and hold it for XX seconds, then go to auto with a mildly tuned loop? good luck, Ken

So....the saga continues, who knows if anything really happened , and if it was meant to do harm.

How about grounding? UPS systems usually have an isolated ground, is the processor ground to this or earth ground?

Many times, companies compile a symbol legend, this avoids confusion, does the drawing owner have a legend sheet?

1. Historize the data values in the Scada system, then print out a graph? or 2. Use the Scada system as a protocol converter, Scada collects values, converts to Modbut tcp, and sends to recorder.

My guess is HMI

I agree with Ken, one off's are hard to justify. If you were going to have multiples of this system, then in house might make sense.

????

Why do companies spend fortunes on equipment and go cheap on controls? Who would ever design a system with 24 analog points and then try and go cheap on the PLC that monitors/controls them. I do not understand the logic. If there was a design need for 24 analog values, why would you not design you control system to handle the same number of values?

I remember.....what a thread..

I usually do it in the plant historian.

Hey Maggie, Welcome to the board.
