  1. Is it possible to setup Ethercat parameters from within the PLC program?  I am facing a situation where a machine is going to have changeable tooling fixtures and each fixture is going to have an EtherCAT device on it.  I am guessing they will need to be setup to look like the same node to the PLC, but they will have different physical IDs and different settings for some of the parameter fields.  They will be the same device so they will have the same parameter fields, just different values in those fields. I can also get these devices with EthernetIP as the fieldbus option.  In that case I would always have a network error because the PLC would always see one of the devices missing from the network.  is it possible to enable/disable Ethernet connections from within the program logic to avoid the error?
  2. Good Afternoon,   We have two PLC's and (L75), EN2T NICs.  One PLC is redundant.  L75 and L77 CPU's.  Over the last two weeks, we gradually lost HMI communications to ONE of the two PLC's.  Oddly, computer/RSLINX could see topics for ONE PLC but NOT the other.  Finally this was remedied by power cycling CPU. . . But then communications to second PLC, between RSLOGIX and CPU stopped working, while HMI comms was restored.  But now, gradually, we are seeing RSVIEW32 stop communicating -- that is, it stops 'seeing' topics on this second PLC, one workstation at a time.  EVEN THOUGH CPU SHOWS UP IN RSLINX.  When I run the OPC Test Utility, and click 'online', it shows no tags for that controller under 'online', whereas the other controller, shows the tags.  When I attempt to go online with the effected PLC in RSLOGIX, it just gives an hourglass.  Plant is running so my ability to troubleshoot is limited.  RSVIEW32 7.40 here under XP (I know it's very old). I even tried a separate installation of RSLOGIX on a laptop, same symptoms.  Even tried USB connection.  When I connect USB to network card, and browse to controller, it just gives endless spinning ball/Bill Gates stopwatch.  When I connect USB directly to controller, I also can't go online. Using mostly Stratix switches.  Also have a Prosoft Modbus card, and an eWeb card.  Problems seemingly came out of nowhere.  Any advice welcome!
  3. I have a fx5u plc connected to 2 keyence sr 1000 qr code scanners using plc link. On random times the plc error light will light up and all ethernet connection will be disconnected and i cannot connect to the plc with gx works 3. If i put the plc in stop mode tho i can connect to the plc. I do not know what error code is causing this because each time i connect the error code is missing. The problem starts when the plc is in run mode. Can anyone help me with this as this is a persistent bug that keeps on happening in my system?
  4. OK,  I have a program in a Control Logix 5561 controller(ver. 19.52) that every time we go online with it, the communication between the PLC and the PC running RS5000 is so slow you cannot navigate the program efficiently. I am new to this facility but I noticed the programmer used 20 different periodic tasks to organize their program, mostly running at 30ms intervals. several are set to 10ms and some are even set to 3ms. I have gone through and found out that the short interval tasks have been overlapped 10's of millions of times, and the combined total of all scan times is over 160ms. I have a strong feeling this could be causing our comms bog down and possibly other erratic behavior but would like a second opinion. This machine has 2 indexing dials, with work stations that do work between indexes, Pick and Place operations, etc.  Is there even a need to be running these with periodic tasks? All thoughts are appreciated. Thank you
  5. Hi I am using a P342020 together with a HMID642 Magelis Panel. Using Unity Pro I have successfully downloaded a program to the CPU via USB. The HMI Panel powers up into 'Initial Start Mode' and is asking me to 'Download the system from your editor.' How is this done? How should the ethernet connections be made? between PC (with Unity Pro and Vijeo), M340 and HMI panel and where do I set all the IP addresses? I guess there is documentation somewhere but couldn't find it...! Regards   Andy

  8. Controllogix 1756-OF8 Wiring help

    Hello everyone!  I am having some issues with the internal wiring/wiring of the 1756-OF8 analog output card in my Controllogix L55 controller. I have just recently started using  Allen bradley products, so please bear with me. If my memory serves me correctly, in my past experiences with other plc vendors I thought I was required to provide 24vdc+ from the power supply, which is common to all the channels used for driving the analog out(4-20ma) to the field device being controlled. But I can find any documentation from Allen Bradley that supports this. Can anyone shed some light on how to connect the power supply to the OF-8 card.   Thank you!! Shane
  9. Good Day, I am seeing intermittent bUs (communication bus) errors on 3 VFD's simultaneously.  These are Yaskawa P1000's with CM092 Industrial Ethernet Cards. There are Stratix 5700 switches between the drives and the Controllogix 1756-L75 CPU.  Happens every day to every week -- intermittent. Reading parameter F6-98, it indicates a 'connection time out'.  I don't understand why I would receive this fault.  IGMP snooping and querier are enabled on all switches, if that matters. I do not have unicast checked but Yaskawa said that didn't matter.  Packet time is 100 milliseconds.  I welcome any input on what might cause this.  One Yaskawa tech said I should set speed to 100 Mbps (now set at 10 Mbps). Any help appreciated.
  10. I had two esoteric question I was curious if anyone might be able to help with. First, I am playing around with way to monitor the internals of a PLC and I was curious if anyone has any idea on why to pull the internal memory off a ControlLogix 5580. Ideally, I would like to avoid just directly reading the config out and reading individual tags. I prefer to be able to get a little deeper.  Something similar to the crash dump, the RSlogix software can generator or something like the S7dump.exe tool for the S7 PLCs i.e. getting at the actual memory in specific memory addresses. Second, I was curious if anyone knew anyway to grab the actual binary are sent over to the controllogix after the RSLogix 5000 processes a configuration file. In this case I am looking for something similar to the binary files in codesys not the project file. This might be an assumption. Maybe RSLogix doesn’t ever produce anything like that but I figured I would ask
  11. Hi All  I'm struggling to a PLC using WAGO's e!cockpit software which I am new to.  In the network tab when I click to select "ETHERNET" from the "Scan Settings" area all that comes up is a drop down with "update selection" which does nothing.  As a result I cannot scan for the PLC's on my network. Has anyone got any ideas on this issue.  I'm running on windows 10, could that be a problem?

  15. I'm trying to understand the basics of using a serial to ethernet converter such as this Comtrol DM-EIP-2101, with Studio5000 code. Basically I have a weighing machine that only outputs data via RS-232 and I need to send that data to a PC that will process it through a Studio5000 program and have the data displayed on an HMI using FTview SE. Is it as simple as just connecting the serial and ethernet to the converter and it does all the work? Obviously checking ip addresses and firmware will need to be verified. The main thing I am unsure of is the process of passing the individual data packets from the machine to the Logix code on the PC,  things like what the weight of the item was, was it over weight or under, etc....  Would there be an AOI or tags built into the software for a machine like this Checkweigher? I've worked with much smaller items like Cognex Dataman cameras and I know you can just use their AOI that allows you to simply call a tag if you want to display information like if a scanned barcode was correct or whatever. If anyone has done something similar I'd appreciate any guidance. It can be difficult getting the information from the manufactures so I'm looking for answers anywhere I can. EDIT: I guess I should also clarify that only using one or the other (serial or E/IP) is not an option. It will be a serial connection from the Weighing machine to the converter and then Ethernet to the PC.

  18. I have OMRON CP1E PLC and I want to read memory address of PLC via serial communication. I want to use ESP8266 OR ARDIUNO OR PC Hyperterminal Please help me in any direction. How I should proceed?  
  19. Hi All, I am new with PLCs. Currently I have a project that required me to send a 12 alphanumeric (2D code scanned) from multiple CP1Hs to NJ101. Then NJ101 will directly send the data into a SQL (haven't made yet). So basically, there are a few hurdle that I face. 1) How send data from CP1H to NJ101.  - I have tried using _CPU010_SendData from CP1H but I'm not sure how to do the ladder or what to use on sysmac (NJ101) side. Btw, I really not familiar with sysmac.  This is the first project that I use sysmac.  - I have read about TCP IP, Fins/UDP and Fins/TCP but I'm not familiar with those method. 2) How to confirm that NJ101 has received the data from CP1H 3) How to arrange the data received from CP1H into SQL - This one I have a sample program that I can follow from my colleague. 4) Setting up a dummy SQL server just for the sake of testing. - I don't have any idea on this. I anyone have an application or software that can used to test the database function, please let me know.   Your helps are greatly appreciated!   Thank you! Bob

  22. All, I have been trying for days to find a way to control a yaskawa v1000 over Ethernet. I have been trying to use explicit messaging but I cannot find the instance class  etc in any of the yaskawa literature. All I can find is to use EDS files with RS5000 but I have a micrologix 1400 and I don't have that capability. If anyone has any recommendations let me know. Thank You, Liam M.     
  23. hy everyone.. I want to communication inverter SJ700 to hmi mitsubishi GS2017 for read an code error in interface HMI? is it possible to communication between them?
  24. Hi everybody, I have a GT2310 communicating with the Mitsubishi F800 VFD. I am using the Freqrol 800 communication driver, connected to the RS-485 terminals of the GOT and on the F800. The comm settings are the same on both devices. I also tried to use the “auto negotiation” setup. I have communication between the two devices. I can read and write to F800 registers.   Anyways, The GT designer diagnostics is complaining about a communication error in the system alarms. The error can be reset but it will appear again.   This also happened when I created a new, empty project where just the communication was setup as described above.   Did anyone experienced the problem and how to troubleshoot / solve this?   Best regards
  25. I am needing some guidance on an application I'm working on. I'm trying to obtain data from a profinet slave device to an Allen Bradley compactlogix PLC. I am using a Prosoft PLX82-EIP-PNC profinet-/ethernet-ip gateway as a median to allow me to access the profinet data. In RSlogix5000, I have created an EIP Class 1 connection for the profinet controller and AB PLC (248 words of input data, 248 words of output data). The same structure is created in the profinet controller (248 words of input data, 248 words of output data). The profinet gateway and PLC are communicating properly. From my profinet slave device, I have a specification that the data is structured within a 23 byte format. Connecting to my profinet gateway, I can see this data. I have attached an image that shows the specification of the profinet data and the data values displayed inside the profinet controller. From the PLC side, I'm needing to be able to see this data and put it in meaningful values. I am using the profinet slave device's internal temperature as an example to work towards. I'm not sure the best way to be able to handle this data and structure it to a meaningful value inside the PLC. (I am using the device's internal temperature as an example to try and get into the PLC).   Thanks,
