  1. 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.
  2. 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  
  3. Firmware Update

    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
  4. 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.
  5. Analog output fault

    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'.
  6. 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?
  7. PF527 opto digital output

    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.
  8. 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
  9. CompactLogix to 1769 I/O Cable?

    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.
  10. 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 ?
  11. 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  
  12. 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?
  13. 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.

  14. 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!
  15. 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... 
  16. 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.
  17. 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

  19. 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!  
  20. 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
  21. 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 ><
  22. Hello forum! I'm using AB Compactlogix 1769 L35E CPU energized by 1769-PA2 power supply which is also supplying to 1769-SDN DeviceNet scanner, both via backplane. Trying to build a simply DN network connecting the scanner to a Balluff BNI DNT-104-000-Z004, which is a 16 PNP digital input block, since is only input module I rely that no extra power supply will be required. The problem is that when connecting both scanner and input block via my DN thick cable (Balluff BCC07YY), the input module does not energize. In fact I got no voltage reading when measuring voltage between scanner V+ and V- terminals. I measured voltage at 1769-PA2 power supply DC output (which is not in use) and its providing 24VDC, also scanner is powered on so I do not think the problem could be power supply nor backplane. Scanner display shows 92 number, scanner manual says that 92 error is "no devicenet power" and has the following description: No network power detected on DeviceNet port. Provide network power. Make sure the module drop cable is providing the proper power to the DeviceNet port. Which I do not get, is not the power supply from 1769-PA2 via backplane enough?  Is not the scanner supposed to provide voltage to the network? I've no grounding connection connected to PE yet (just between devices GND terminals)... is that a problem for testing this small network? It will be done soon but now I'm waiting for cable material. Actually I'm online using Studio5000 and have 1769-SDN DeviceNet scanner device declared at the project, there is no warning nor major fault displayed from the software. Thanks for reading.
  23. 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. 
  24. 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!
  25. I need to run 4 exactly same devices with 4 different controllers. The logic for them would be exactly the same but the IPs and controller names would be different. Is there a way to do it using 1 project file? Basically whenever download is done the logic would be downloaded but the controller name/IP would be left unchanged. They will be connected to the same network so the IPs must be different. I am using 1769-L32E for these and all racks are set up exactly the same. Any ideas?
