A little Fx help please?

[kevin stone]

Here is my problem.
I am on a job intigrating a
http://www.bacharach-inc.com/hgm300-rdm800.htm Ref monitor into Fx60 we couldnt get the modbus to read ( spoke to the factory and he said it would be a no go). Sooo
The question is the unit gives out 2 analog outputs Ao1 and Ao2
Ao1 increments one Ma per zone in a round robin approach (5ma= zone1, 6ma=zone2 ect)
Ao2 represents the ppm level in that zone.
The system has 8 zones and I would like to have a table that looks like this

#1 ??? ppm
#2 ??? ppm
#3 ??? ppm
ect

i am wondering how to store the vaule read for zone #1 until the next cycle pushes the old number out and sets the new number.

Thanks in advance
Kevin

Try this out - I've built it for three zones, but it's fairly straightforward to expand it to as many zones as you need.

Attach the AO showing the zone's ppm value to the ppmAO block, and the currently-displayed-zone value to the zoneDisplayedAO block, and you're in business.

Hi Dave
Did you attach something?
Thanks

Looks like the attachment broke...I'll try to post a link to an image-hosting service so you can see the screen shot you'll want to copy...

Try this - this will show you all the kitControl blocks you'll need to use, and all the links you'll need to make...sorry for the attachment trouble...
