Connect Masterflex Peristaltic Pump with CP1L -EM

4 posts in this topic

Hi All...

I'm still having a trouble on Analog Input adn Ouput especially on it's output where I Connect a Peristaltic Pump to CP1L-EM 

I have 1 set of Masterflex Pump Drive Model 7557-02 and it's controller 7557-04. On the back of the controller there's a DB9 Port for communication with it's remote. Which i don't have the remote.

On the manual attahched, on page 3-2 describes the port configuration.  Is it possible to control it by PLC with it's Analog Output? I have CP1L-EM30DRD that combines with MAD44.

I've connect the Jumper Pin 6-7 and 4-5(From DB9) to digital output of my PLC, and 1-3 to analog output MAD44. I've read and do the manuals for the analog output, but the plc still can't read the masteflex. Or is there there something wrong or missing that i shoud do first?


In the program attached, there's also Scaling for Analog input, has i done it right? i also have try to use the FB that use in Analog Input like the example in the forum download section just to check the result of my scaling. there's a slight difference that makes me have little doubt on my scaling.


Thank you all...

It looks to me like your range data is not properly set for the outputs.

Please review Manual W462-E1-08 pages 468 and 469.

Hope this will help.

Thank you for reply gtsuport,

Hmm..I Think the range data is suitable..

I use 4-20ma for Input analog 1 for the pressure sensor = 800E at 102(For Analog Input 2 and 1) and the address in The PLC for Analog Input 1 is "2"

and use 0-10V for the controller of the peristaltic = 8009 (For Analog Output 4 and 3) I put the controller on the Analog Output 3,and the address in The PLC for Analog output 3 is "104".


Or have i calculate the range code is wrong?

I apologize.

I did not properly read your plc logic when I reviewed it.

Your values are correct.
