  1. Hi Everyone..I'm having hard time to read Analog Sensor. I've try to read the manuals about expansion module, but still having hard time to understand it. My PLC is CP1E-N30DR-A connect with Expansion CP1W-MAD44 and I'm trying to connect with pressure sensor Omron E8F2-B10C that in a certain pressure will trigger to open a Digital Valve. is there something wrong with my setting for range? I do the setting in 4-20mA (0-5V) I attached my Program and Picture while running, the program is only for reading the pressure sensor. the result is  -600 to +600, is there a way to earn the actual result? I've tried Scaling and APR, But didn't understand, is there a guide/tutorial for it as well?   Cheers.. Albert TEST.cxp TEST.cxp
  2. SMC pressure sensor

    Hi! Allen bradley PLC RS Logix 5000 I have a problem with a SMC pressure sensor (ISE30A if I remember correctly). When I monitoring the raw data from the ananlog module, I get about -7710 value, when the smc display shows about 0. There are another SMC pressure sensors too, and if the sensors displays shows 0 then the values what I get form the analog module is about 0 too, so the others work properly. But this one don't.  I already check the wiring. I have no clue waths the problem. Any idea from anybody? Thank you for your help.
  3. PID regulation PT

    Hello   Does someone have a good way to control pressure using PID in cx-programmer? I got two pumps and one PT(4-20mA) Half the year only one pump need`s to run (about 3bar)  but in the season (i work in a fabric) two pumps need to be running (about 4bar needed) except in the night. I`m going to use HMI for adjusting the setpoint so there is no need for any clock/date for this to change itself. The question is how to get one of the pumps to shut down when the need for pressure is not so high. And get the pumps to change "main" pump sometimes so one pump is not running all the time.   Hope this was understandable
