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
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
