  2. FR-DU04 (FR-A500) vs FR-DU04-1 (FR-V500). Programming unit differences. (A VSD question) What is the difference between these units? Why are they not interchangeable. (Other than the fact that the FR-DU04-1 is used for vector VSD applications, and the FR-DU04 is intended for standard induction motor applications. Is this a matter of firmware differences?

  6. Help Programming a Beckhoff PLC

    jnatzic posted a topic in Other PLCs

    I have a very simple problem that I need help with.  I have some programming experience but I am brand new to PLCs and structured text.  I am using TwinCat 3 to program a Beckhoff CX9020.  My goal is to read the temperature from my thermocouple and open or close a valve based on the temperature.  I have successfully connected the PLC to the TwinCat software and I am able to see the value of the thermocouple increase and decrease when I touch it with my fingers.  I need to link that value to a variable in my code so I can have the valve act on it.  I don't know how to properly address the inputs and outputs.  Thank you!

  11. Hi, I am a beginner to PLC. I am currently working on a home project with Allen Bradley 1100 model. The project is to build a door open-shut cycle tester.  The motor I have purchased is a Bodine Brushless DC34B/FV INTEGRAmotor. My goal is to utilize the Allen Bradley to to control the motor and then the motor drive a shaft to open/shut the door. Through the LCD screen the of PLC, we can set and view the amount of cycles.  I have finished the initial stage of wiring. But not sure how should I start on the programming part. Could any of you give me any hints on the programming portion? Thank you so much.

  13. hey!  I'm pretty new to PLC's, and I'm supposed to ''teach'' the people at my internship how this PLC works, but I have encountered a problem.  I've gotten pretty far with all the digital programming and understanding how everything works, but I just can't figure out how the analog inputs/outputs and programming works...... I've had a fair explaination on PID and how this works. I've searched the web as well to figure out what PLC instructions to use.    I hope you can answer my following questions.    1, what are the most used PLC instruction blocks which I can use for temperature control, and how am I supposed to use them? 2, Could you please give me an example on how to use PID and what numbers will I need for the calculations? 3, what are the most used PLC Instruction blocks (apart form the analog ones) that I should include in my tutorial?   this is my setup: Ethernet switch MOXA EDS-205 Plc voeding PA202 PLC CPU CJ1MCPU11-ETN Digital IN (16x) CJ1W-ID211 (SL) Digital IN (16x) CJ1W-ID211 (SL) Analog IN (8x) CJ1W-AD081 (SL) Analog IN (8x) CJ1W-AD081 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) Analog OUT (4x) CJ1W-DA041 (SL)   thank you soo much for looking at my question and considering helping me! the OMRON helpdesk hasn't been very helpfull.    kind regards,    Deuslupos,

  20. Hello, I am trying to connect an OMRON CMP1-30CDR-A-V1 to my PC. I used a CQM1-CIF02 cable which I connected to RS232-USB converter and then to my laptop. Is this the right way to do it? I have seen on the OMRON website the attached diagram. Should we use that device or an RS232-USB converter will be enough? Also. I tired to use a PC with RS232 port directly but it also failed.

  23. I am converting a PLC-5-40 processor that also has a SST side car for Profibus Dp communication to BK3100 modules on the equipment. To a Control Logix L-72 processsor using a Molex SST-PB3-CLX card to the Profibus modules. Everything went some what smooth until I got to the SSI transducers in the Profibus. The word arrangement is not coming in the same as with the PLC-5. Is there anybody else that has run into this problem and is there a solution. I have contacted Molex, Balluff and Beckhoff the first 2 got back to me I am still waiting on Beckhoff.

  25. I wonder if anyone can recommend cable id printer? I know Brady is the leader in this field and I have used their products in the past but I wonder if anyone has used any other manufacturer they can comment on? I found the K-Sun Green Machine but I am not sure how does it compare to lets say Brady BMP71 and how much more expensive or cheaper their consumables are? Any other products worth mentioning?
