Hi, I cannot give you a call as i am in new zealand and the PH number wont work. Can you please let me know or point me in the wright direction as to where i have gone wrong please?

I have realised that i had both the PID and Analog using V3000, i Have changed them and now have this setup:

For the first scan SP0 i have:

LD K8081 - use only output 1, and no inputs

OUT V720 - Use Slot 3 chanel 1

LD O4000

OUT V721

LD O4010

OUT V722

and in the output part of the PID loop i have:

LD V3005 - Control output of PID

BCD

OUT V4010 - output 0-4095 signal to analog card

Tom,

Technically you do not need the input setup LD K8081 only LD k81, OUT V720, LDA O4010, OUT V722.

Are you using LDA O4000, LDA O4010 respectively?

You do not need the BCD command, you have the data format in V4010 set for binary.

What CPU Version of firmware? You might should upgrade if very old, current is 2.30. http://support.automationdirect.com/firmware/binaries.html

To Upgrade you will also need the Koyo Tool. http://support.automationdirect.com/firmware/index.html

Hi, i have a pid loop that is adjusting an analog output signal that drives a proportional pneumatic valve. Using PID view i get the process variable changing in the right Vmem locations. I have set the analog out card up (F0-4AD2DA-1) using the pointers method and it is installed in slot 3 of a DL06DD.

When trying to measure the 4-20 mA signal i get nothing with a DMM. when i connect the proportinal valve up it also doesnt respond.

For the first scan SP0 i have:

LD K8081 - use only output 1, and no inputs

OUT V720 - Use Slot 3 chanel 1

LD O3000

OUT V721

LD O301

OUT V722

and in the output part of the PID loop i have:

LD V3005 - Control output of PID

BCD

OUT V2010 - output 0-4095 signal to analog card

Does this seem correct? It all seems to be working correctly on the PIC View screen!
