  1. Hi and thanks for youre time  I am a newbie trying to connect to a 1769-L30ERMS using an Ethernet cable. I am using Studio 5000 and RSLinx Classic lite for programming and communication. However Studio 5000 and RSLinx Classic lite are installed on av virtual machine using VMware.  So my problem is two fold. Connect the VM so that it reads from the real computers ethernet port Find and communicate with the PLC from the VM There are guides on how these problems are addressed seperatly. For example and however I have not been able to get them to work together. So I was wondering if you, the sages of PLC programming might have some tips or trix that I could test or perhaps even a guide for how to do? Mvh Eric
  2. FR-A740

    Hi One of my friend want use more analog output on his vfd. Its a Mitsubishi FR-A740 type. Currently the AM signal is for current, but he needs the speed and frequency too.  As we saw its only one analog output is avaiable, but you guys might know better. Can someone confims our theory.   Thank you.
  3. Hello, I am trying to flash an indicator light (Banner  K70LBGYRPQ ) every .5 seconds.  The PLC manual says 2.5A per channel.  The light uses roughly 113mA max current @ 24vdc.  I am using output 0 to do this (O:0/0).  I think I may have ruined the output by flashing the indicator light.  Has anyone ever experienced this before?  Is there a minimum pulse time for this PLC?  What do people normally do when wanting to flash an indicator light such as this?  This is not the first time I have seen this happen.   Thanks in advance!
  4. Hi,I want to read transducer signal on PLC.I am using 7kg60008ab/nn transducer and it's analog (4-20mA) output is connected with analog meter.Can I connect the transducer current output (4-20mA) signal to PLC analog input in series with analog meter display???So that I can read the value on PLC simultaneously with analog meter?
  5. Output polarity selection

    Hello to everyone. Nice to meet you all. How are you? I hope you are doing well. I’m developing a program with the purpose of make something similar to a pulse train in the output. However, sometimes I need the output to be a “positive” pulse and sometimes a “negative” one. By positive and negative I mean the polarity in relation to the pulse train source. I’m trying to use a pair of bits in order to switch between the two choices of polarities. I attach a simplified version of the ladder diagram I’ve made. When I thought about the logic, it seemed logical to me, however, it isn’t working as supposed. SM0.4 is a pulse train source. According to the software manual, it is a pulse train with 50% duty cycle and a cycle time of 2 s. That it to say it says at TRUE for one second and return to FALSE for another second. I assign the value of that variable bit to the M0.0 memory bit. I get the negative version of the pulse train logically negating it in the Network #2.                 I assign the value of two inputs, I0.0 and I0.1, to other two memory bits, M0.1 and M0.2. ·         When both inputs are in a FALSE state, the output stays FALSE, disregarding the state of SM0.4. (Case #1) ·         When I0.0 is TRUE, M0.1 is TRUE. However, Q0.0 stays at FALSE no matter SM0.4 is TRUE or FALSE. I attach a pair of pictures. (Case #2) ·         On the other side, when I0.1 is TRUE, M0.2 is TRUE. In this case, the output shows the correct behavior. It is the negated version of the pulse train source. (Case #3)                 Has any of you experienced something similar? Is there a better way to execute my purpose?                 I’m not executing the program, just simulating it with KincoBuilder from Kinco. However, it has always worked fine for me. Thanks for you attention. I look forward for your responses. Kind regards!
  6. Hello guys, how many (maximum) analog inputs/outputs can CPU 1215C can reach without any issue?   I try to search in google but can't find convincing answer.  Thanks for your help.
  7. Hi everyone, To explain the problem a little bit: I have 2 systems that are equal, they have 1 PLC, 1 Inverter and 1 Servo Axis (Image01). The devices are connected via EtherCat. The thing here is tht in these systems the PLC and Servo Axis is the same but the inverter is different. My goal is to have the same project on both systems and depending on the inverter detected use the correct program. What worked: If I add the 2 Inverters and 2 Servo Axis on the project on different nodes (Image02), I can detect which is present using the variable _EC_EntrySlavTb[n]. My issue is that if I want to make more replicas of the systems using different inverters I will eventually hit the Axis Number limit for the PLC while in reality I am only using on Servo Axis at a time. What I wanted: I would like to be able to control 1 Servo Axis with 2 different inverters (only one active per PLC) (Image03). What I tried: The axis parameters can be set using a variable of the type _sAXIS_PARAM, however it seems that the option to change the axis basic settings is not available (Manual: NJ/NX-series Motion Control Instructions Reference Manual (W508) page 5-58) (Image04). The axis basic settings is where the definition of the output device plus control words are set (Image05). Is there a work around to solve this issue? I would really like to avoid having to manually change the output device for the Servo Axis every time I make an update on all the systems.   Best Regards, BR  
  8. I am looking help with an issue I have trying to connect to a 5370 Controller 1769-L33ER. The controller firmware is 20.014 and my studio does not have 20.014 firmware. I have downloaded the firmware and do not know how to get it extracted to my PC. Any help with this will be grateful.  Regards
  9. tldr: How can I release/close CIP connections to a 1769-L35E CompactLogix (rev. 17.12)? Starting having communications issues with the controller out of nowhere - no recent changes, been running for years, etc. Tag update rates on the Wonderware InTouch sessions are really slow and could not get online with the controller until the Wonderware DAS was disabled, thereby freeing up a connection. Max number of allowed CIP connections is 32, but, per Task Monitor, there are 35 active connections. How can I drop all CIP connections so that only the valid ones come back? Anyway to do it without cycling power or going from run->prog->run? There are a number of cached message blocks, a  1794-AENT FlexIO Adapter, 10 other generic ethernet devices, and the connection to the WW DAS.   Thank you for your help.
  10. I have an analog output card 1734-OE2V. As a default, there is selected fault mode as 'Go to Low Clamp'. I am using output range -10V to 10V. What is the value for Low Clamp. Is it 0V or -10V? If I want it to be 0, do I need to select 'use fault value' and set the fault value to '0'.
  11. FX3U Output

    Hi,   we have  a FX3U 128 PLC. I connect 24V to COM and all the output in the partition Y0, Y1,.. have 24V even if some output are ON and some are OFF. Why?
  12. I need to use digital outputs of PF527 drive. Controlling the outputs, it does not do anything. Relay outputs are working fine, but opto outputs do not work. For the outputs, there are relays connected, using pin 6,7 and 17.
  13. Hello Im using a 1769 HSC card with a L35E and trying to get the RPM. Ive been reading through forums for a couple days trying all the ideas from people who have had similar issues but I still cant get the current.rate(x) working.  Im using a single channel encoder at 60ppr. I believe the card is set up right and the channel is enabled. The counter seems to work fine but the rate stays 0 when im spinning the encoder slow but will jump to  100 or 200 if I spin it fast.  Any help would be appreciated. Thanks
  14. Looking for some help that i cant seem to find online - I have a  CompactLogix 5370 L1 Controller part number 1769-L16ER-BB1B and would like to connect a 1769-IF4 and a 1769-OF2 Analog expansion modules. Rockwell sales tell me they are compatible The Compactlogix looks to be a "slide in" and the expansion modules are Plug Type. Is there a cable or base rack I can use? Thanks in advance.
  15. Evening, I struggle with simple task... I need to activate PLC Output at the specific time of a day. I`m using GSV to obtain PLC time, data is being moved to DIN[7] registers. Then I have three EQU (Hour / Minute / Second) and at the end of rung there is OTL for output. Rung below I have two EQU (Hour / Minute) to disable output at different time - OTU. However every time OTL is energised , OTU on rung below is fired too. What am I doing wrong here ?
  16. Hello, I need to control a stepper motor(have stepper driver) using NX-PG0232-5 with NJ301 PLC. The function is simple, i need to run the stepper motor continuously at a specified velocity. So, in NX-PG module I've made the settings (Ch1 output mode as "Velocity continuous pulse output") and given the tags to IO (as shown below, sorry i'm not able to attach image). I've also added the initialization program to switch on the vfd. Now to move continuously i should should just give speed in pps in "PG_Ch1_Command_Velocity" right?      Ch1 Controlword    Control word 1    W    WORD                 Ch1 Switch On    Switch ON for pulse output 1    W    BOOL    PG_Ch1_SwitchOn        Global Variables     Ch1 Enable Voltage    Start turning on the power for pulse output 1.    W    BOOL    PG_Ch1_Enable_Voltage        Global Variables     Ch1 Quick Stop    Immediate stop for pulse output 1    W    BOOL    PG_Ch1_QuickStop        Global Variables     Ch1 Enable Operation    Start operation for pulse output 1    W    BOOL    PG_Ch1_EnableOperation        Global Variables     Ch1 Fault Reset    Reset errors for pulse output 1    W    BOOL                 Ch1 External Output    Aggregated data of external outputs for pulse output 1    W    BYTE                 Ch1 Command Position    Command position of pulse output 1    W    DINT    PG_Ch1_Command_Position        Global Variables     Ch1 Command Velocity    Command velocity of pulse output 1    W    DINT    PG_Ch1_Command_Velocity        Global Variables  
  17. I have a Base tag of BOOL logic that will not activate the MOV output.  The Base tag is paralleled with an Alias tag for a NO pushbutton.  When the pushbutton is actuated it produces the desired output.  Has anyone encountered this issue from a togglebit base tag before?  Why would a base tag produce a different outcome from that of an alias tag that function properly?

  19. 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!
  20. 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... 
  21. 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.
  22. 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

  24. 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. ( 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!  
  25. 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
