  1. rc01cpu and r60da4 help needed

    Hi every body, could you please help me; i have a mitsubishi plc serie iq-rwith the followings modules:powersupply r61p, r01cpu , rx40c7 inputs , ry10r2 outputs , r60adv8 analoginputs and r60da4 analog outputs. i am newbe with mitsubishi plc ;i would like to learn using the analog output of the R60DA4.for exemple i would send a digital value to the ch1 and convert it a voltage that i can mesure on the output of channel1.i have tried but i didn't succeed.i am using gxwork3.i have configured channel1 as +10v -10v output, normal mode , normal output;then i made a simple program in sfc to try this conversion but i get nothing in the output of channel1. i found that the digital value should be sent to the adress D11 wich is the adress of channel1.here you will find the file i made with gxworks3.could you please help me.

  2. Good Afternoon  im a complete newbie when it comes to PLCs but have done plenty of PIC programming in the past. I've been gifted a couple of FX0s 20mr units to try to repair something I made with PICs years ago. It got damaged during a move and I can’t see well enough now to make PCBs anymore so thought that this might be a solution. The basic operation is  1. switched on 2. motor A moves till hits limit switch (X000) 3. Wait 2 seconds 4. motor reverses till hits second limit switch (X001) then once this has been completed then the following  5. Motor B turns clockwise for 30 seconds then stops  And while Motor B is turning I need Motor C to turn until hitting limit switch (X002) I then need to get it to repeat on the press of a button but I need to reverse operation of Motors B and C I am using double position relays to drive the motors so motor A is on Y000 and Y001 if I power either relay the the motor turns in that direction. Same with Motor B and C Y002 to Y005 is this something that’s possible with one of these controllers or am i going to be programming a PIC to control the PLC ?   All the various COM and powers are connected up, I can individually make every motor do what I want, but the program doesn't flow from one item to the next. but this is probably just me      
  3. Hi all,  I am in the process of doing a project for some school work and need to do a SWOT analysis of the latest modular PLCs from Mitsubishi (R series), Siemens (S7-1500) and Allen Bradley (ControlLogix).  So I thought what better way than to ask the people on what they think are the pros and cons of each! Thanks for your responses in advance!
  4. Best Practice Rack 0

    Is there any reason not to have input and output modules on the same rack as the processor and Ethernet cards? We have RIO’s and sometimes have networking outages, I want to move critical IO to Rack0 the same rack as the processor, is this bad practice?  I've seen architecture for BMS that only have Ethernet cards and processors in Rack 0... 
  5. Control Panel

    Is it possible to view the values / states of all inputs, outputs and workbits (e.g. 64.00 through 64.15 on Omron CQM1 PLC) on a single screen or control panel within CX-Programmer software?  I'm trying to troubleshoot some ladder logic that I wrote and need to know the values of 5 or 6 inputs/outputs/workbits simultaneously.  Having to scroll up and down through my ladder logic repeatedly does not work well with code that changes state every 5-10 seconds or so. Any help is welcome.
  6. Using a AD041 and DA041

    Hi, I'm using a CJ2M CPU 33, and also a CJ1m Ad-041-V1 Analog Input and DA-041 Analog Output card.  I am using the Analog input to measure my current in my one heating application and  Ihave that reading and scaled correctly, but now  I want to use my Analog output to replace the Rheostat  we have in the system. I'm having some issues setting the range and getting voltage to vary. I also am a little new to Analog Outputs and don't know what I'm doing wrong. I have attached my program here. Any help would be greatly appreciated. Analog Heat.cxp

  8. OD212 Card Outputs not powered

    Hello! I'm running into a problem with a malfunctioning OD212 output card on my PLC.  I figure the problem has something to do with my wiring, because I've put 2 different cards in with the same results. The card is unable to switch any of the relays I have as outputs although the indicator lights on it are functioning as expected. The setup it is in is: A PA202 power supply, followed by a CJ1M CPU13 CPU, 2 ID211 input cards, and 3 OD212 output cards. The bad card is the second OD212. All of the other cards work fine, it's just this one that's been having problems.  8 of the terminals on the bad card are hooked up to relays that each draw 0.02A and two more are attached to relays that draw 0.05A. So in total that's 0.26A if all the outputs are on at the same time (which they never will be.) I saw someone was having a similar problem to me on the forum, which was solved by switching out the PA202 supply, but that didn't work in my case. I don't think the problem lies with the PLC or the card's placement in the rack because I switched the card's position with the one next to it (output card 2 switched with output card 3) and tested that card (output card 3 in output card 2's place) without hooking it up to the original wiring and it worked just fine. However, I was still getting the same issue with the bad card even though it was in a different position, leading me to believe that I fried it somehow. Some other quirks of the bad card are that its outputs do not turn on and off with the indicator lights like how the other OD212s do. Below is a link to a video that shows this. The bad card has already been switched with the one next to it in the video - so it's on the end, but it's original position was second to last. https://youtu.be/wTvvGCHFpsc ( you may want to watch it at half speed ) So what I'm wondering is: how am I frying these cards / Is the problem easy to fix or will I have to send them to Omron? Thanks in advance!  
  9. Hi there, is somebody experience whereby the output of the 1769-OF4Ci is not responding on the value entered?.  Setting: 4-20mA Res: 0- 32767 - PID set whatever value I key in the output current remained.  please help. Ganie
  10. I am new to Automation Direct software and how the programs are written. Can anyone explain how they handle the analog outputs? My processor does not support the IBox that makes life easier, so I am having to do it the old hard way. I understand most of the logic of how its done for sending data to one channel but I don't understand how the channel selecting works. Can someone give me a programming example or explain how that works? I am looking at the online manual that Automation Direct provides for you for the analog module but I am having a difficult time trying to wrap my brain around how they do their analog stuff ><
  11. MC protocol

    Hello once again, before I'll dive into mitsu manuals, does anyone of you know if there is some special relay signaling that PLC (FX3GE) have lost communication via MC protocol? Thank you in advance
  12. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob.

What should i do..?? or do i need to communicate it with Siemens PLC..?? If so which PLC should use..??
  14. ANALOGIC BIPOLAR OUTPUT - HELP

    Hello everyone,   I'm a student who recently started programming, and I could really use some help.  I have a CPU-31 CJ2M OMRON PLC and a ADO41-v1 analogic card. I need help programming an analogic scale with a bipolar signal -10V to +10V to then control a drive, which will then control the motor. If anyone could help me out of give me some examples I'd be really thankfull.   Thanks!
  15. Gang, Hooking up an Automation Direct P2-32TD2P to an AC/DC LED and noticed the LED is always "on" a little bit. When the output is on, the LED is certainly on, but when the output is off the LED is still on by a fractional amount, not much but it's plainly noticeable the room lights are off. The CPU can be in Stop, no matter, power just has to be on. I think this has to do with the card's load disconnected error functionality. +24V and some fraction of amps is always present at the output whether the output is on or off. I talked with automation people at work who noted there is an Allen Bradley system that does the same thing, it caused them a problem, they had to use a relay or etc to make an off output actually be off. Has anyone dealt with this? I'm new to the Productivity software, but there doesn't seem to be a way to just turn it off in the IDE. It seems ridiculous to have to wire up transistors or relays just to have off be off. Thanks for any ideas.
  16. Relay Digital signals

    I have a CJ1M-CPU13. It will be used for a prototype and later if successful, a better PLC fit will be employed. This system does not have the ability to drive pulses for servo control. However, will this system relay a digital signal at ~1kHz? I also need the PLC to count the pulses, reset at 1000 and start again continuously and never miss an input pulse. I see that the published transactions give  <15 microsecond decision times. I would think it would be no issue. Thank you.
  17. Hi, I would like to provide the PLC control for a scenario where the temperature in a machine, heated by the two electric heaters, is controlled with use of 1 TCK and 2 s/s relays. Please see draft “plc4” sent attach. The TCK is fixed to the machine and is not in a physical contact with the heaters. Nominal temperature of machine is 200degC. The machine temperature tolerance is +/-2degC. This means that the heaters should be turned on when machine T drops to 198degC and turned off when T reaches 202degC.  For this moment I have created the start PLC diagram outlined on draft “PLC4”.  I am still learning PLC. Therefore, I would be very grateful for your opinion whether the PLC diagram shown on picture “PLC4”, in terms of the tools used (direct contact, direct coil, etc.) and their layout, is of proper design. I know that there is much more work needed to complete this task (e.g. set up of the variables, etc.). I am using Unilogic software. Please help. Regards
  18. I want to unify my programs and select only configuration words (the same program for many applications) . My problem is with the assigned outputs by the high-speed pulse output like PLS2, ACC, ORG ... I thing that the instructions JMP/JME may allows to use these outputs as normal outputs when HSPO functions is not required. Is it right ?
  19. Good afternoon Mr.PLC forum members.   We recently had a fuse blow on the wiring between a 1756-OF6CI analog out card and a control valve (which we have no feedback for - only the 0-100% output). Took a little longer to troubleshoot since we have no feedback and we also don't monitor individual channel status of the card. For input cards (1756-IF8H or IF16H), it's easy enough to use the under-range/over-range or broken wire signal to troubleshoot a blown fuse or bad connection, and activate an alarm. I have been told by our local consultant-technician that there is an equivalent monitoring bit for output cards. Reading the instruction manual for the 1756-I/O cards, the fault channel bits do not seem to have this type of function for the 1756-OF6CI. The fault bits only seem to look at the requested output values, and at the connection between card and PLC itself as far as I can tell.  Am I missing something?   thanks for your help
  20. I hate to start a new topic on such an old processor but I forced to keep this thing working until I can upgrade it.  We are having funny issues with outputs.  At first they were on a PLC5/60.  We suspected a bad processor so we changed to a PLC5/40 we had in our tool crib and the problem didn't go away.  Some of our outputs in the ladder are being evaluated to true but not turning on.  We can force the output on and it will come on and when we remove the force it will turn back off.  I've never seen this problem before on any processor.  All the logic leading up to the output is true but the output is not turning on and is there not green. I've already checked all the obvious causes.  The instruction is an OTE.  The output is not duplicated somewhere else in the logic that is turning it off.  The ladder file is being scanned.  I replaced the output with a B3 bit and on the next line had the B3 bit turn on the ouput.  The B3 output bit turned on but the output did not.  This output is on a remote I/O rack and other outputs on that rack are working. Any ideas would be greatly appreciated.
  21. Hi All, We have an old machine using a Mitsubishi Fxo-30MR/ES and I will be replacing the PLC with a FX3S-30MR/ES.  This old machine would power some led's on a panel mounted PCB using the PLC outputs.  The 24V from the PLC output would go to the PCB board where a resistor would drop the voltage for the LED.   This PCB is damaged I would like to avoid getting a new PCB made and instead power some panel mounted LED rated for 24V directly form the PLC output.  I guess these panel mounted LED have a built-in resistor.  Power consumption for the LEDs are 20mA at 24V volts.  The 24V power supply has plenty of capacity for this. Are there any issues with doing this? I have attached the spec sheet for the panel mounted LED (I will be using the 24V versions).   Panel Mounted LED.pdf
  22. Hi I am searching for plc having negative analog input and output. i.e. 0 to -10v analog i/p and Analog o/p.  Can any one help me in finding plc which has this feature .  Thank You  
  23. Fx3g Binary bit Output

    Hello, Need your advice. I am trying decimal number convert to binary and do output. for example If inside  D90 I have 11 decimal number then for me need active output Y0, Y1 and Y3. I tried make this code below, but it is not work, don't active output . Maybe fx3g PLC have function how need to do it?
  24. Elecrical Control Panel

    Which type of electrical panel is most reliable, give some idea about that ..?
  25. Hi to everyone, I use PowerFlex 520 drive on profibus (with adapter 25-COMM-P) for first time. I managed to start/stop/reference drive using Logic Command/Status I/O but didn't manage to get output current using datalinks mechanism. I configured DP master (Mitsubishi Q PLC, QJ71PB92V) as shown in the attached picture. The main problem is that trying to modify C161-C164 (Opt Data In 1-4) parameters drive does not accept the entered values and it turns back to value "0". First, I disabled I/O connection with the controller Disconnecting the drive from the network. On the other hand, drives allow me to change parameters C165-C168 (Opt Data Out 1-4) but these are out paramenetrs (from the controller's point of view). Is there any guy that managed to get the output current  in any way on profibus network? Thanks a lot for your help in advance! I post this message in Allen Bradley Forum, too.
