  1. Hello I'm looking for a way to setup communication between a PC and a PLC. The PLC is an Allen Bradley compactlogix L30ER i would like to use the existing network which is a Ethernet setup. I've read and tried some OPC/DDE sample project with Excel and I'm wondering if there is a better way to do it. Thanks!
  2. I forgot how to do this. If I put in let's say 1234569632<cr><lf> how do I store the carriage return line feed along with the number in my ST file??? 1234569632(chr$13)(chr$10) something like this, but can't remember. Thanks
  3. Hello! I'm working on a project. I cannot get online with the PLC. The compagnie who made the program does not exist anymore so they cannot help me. Does anyone knows how to unlock a locked controller ? Do you know a compagnie who can solve this kind of problem ? Otherwise my only option is to wipe the all thing and reprogram it .... which would be bad. Thanks !

  4. connecting ixt4a to a cj1m/cp1l/ns network

    geomariolis posted a topic in Omron

    hi everybody i have a network with 2 pieces cj1m and 2 pieces cp1l communicating with a ns15 monitor. everything is fine. i need to connect an ixt4a monitor in that network. my question is : do i have to make new routing tables or it is not neccessary? my routing table for cj1m and cp1l cpus are attached. if then i have to make new routing table so that the cj1m will be able to communicate ixt4a monitor, how am i going to do it for both monitors? Any help will be mostly valuable and appreciated. thanks
  5. Hello, my question today deals with a particular way of coding in RS Logix 5000. I have two routines ( titled "Gauge" and "Alarm"). where rung 10 in Gauge is the exact same as rung 2 in Alarm. How can I make a change to rung 10 in Gauge and allow the program to automatically make that same change in rung 2 of Alarm? The only reason these two routines have the same rung at 10 and 2 respectively is to make trouble shooting easier whenever an issue arises. So instead of searching through the "Gauge' routine to find out where the fault is, I can easily look at the "Alarm" routine and find out what the problem is. I just want to be able to make changes to the Gauge routine and find someway to allow the program to automatically update the exact same rung in the Alarm Routine. Thanks.
  6. Good day, I´m helping with small project and currently i am stuck because of this problem. And I hope you can help me out. I´m using PowerFlex 525 connected with AB CompactLogix 1769-33ER PLC via EtherNet/IP. Connection is working, I can read and write values from/to 525. To configure both devices i´m using RSLogix 5000. 1) First problem occurs after I loaded configuration to 525 and it´s, that 525 keeps overwriting values of Accel and Decel Time 1. It happens when i directly change parameters in Module Properties (online) or after I upload configuration to device. It happens even if i set parameters directly to 525 with its HMI panel. - I kinda get around this problem when i use Accel/Decel Time 2 for Step logic, but if i send direct reference value motor still jump to it and that is not good, especially when changing direction of rotation. 2) Second problem is that I cant get Speed Sources and Start References right. Usually Is working only option 1 and others are not, or they are doing something else that they should. For better imagination this is what i want to do: I have 3-state switch (left = 1 ON(DigIn TrmBlk 02), 2 OFF; center = 1 OFF, 2 OFF; right = 1 OFF, 2 ON(DigIn TrmBlk 03)), In center position I want to control 525 with EtherNet (already working when: Start 1 AND Speed 1 = EtherNet/IP). In left position I want to control motor directly with Drive Pot and In left position a want to start Step Logic (which i have already set) - Funny thing, If I set Start 1 = Ethernet, Speed 1 = Step, Start 2,3 = DigIn, Speed 2,3 = Drive Pot then in all three position motor goes in Step logic.. Or when i get left and right position working then Ethernet is blocked.. and this kind of things.. I Attach print-screen of my current settings, if you need something more just, tell me. Thank you for your time, and I hope someone will be able to help me.

  7. CJ1M communication protocol

    WKla posted a topic in Omron

    Hello, I am not familiar with the Omron PLC's. A PC is connected to the peripheral port of an CJ1M CPU12 PLC. The write command the PC is transmitting to the PLC looks like this (ASCII): "@00WD0070010055*." Can you tell me what kind of communication protocol it is using? It is a public or proprietary protocol? Thank you!
  8. Hello, I am trying to communicate with MicroLogix 1100 from CompactLogix. But I keep getting an error and It says connection failure. This is what I have done so far. Can anyone tell me what I am missing? Regards,
  9. Automation professionals, I would like to read the display values of a red lion DP700 in a control logix PLC. I was able to successfully integrate both devices through EtherNet / IP and I am geting the corresponding values in a DINT register in the PLC. But the problem is that the value in the PLC register is not in the same format as in the DP700 display. The display reads the length of a product in inches like 288.484 etc. Where as the value in the register is a 10 digit number like 1133526516. For sure, there is a definite correlation between these two values but I am not able to figure out the exact relationship as a function of a formula. I have given below 25 data pairs for your analysis. I tried to find out the scaling factor (slope and offset). The scaling that I found fit the first 10 records but did not fit the remaining 15 records Can you help me to find out the relationship between the ? # DP700 PLC register 1 288484 1133526516 2 288627 1133531202 3 288631 1133531333 4 288739 1133534872 5 288741 1133534937 6 288742 1133534970 7 288746 1133535101 8 288757 1133535461 9 288776 1133536084 10 288796 1133536739 11 241060 1131482972 12 241043 1131481858 13 241027 1131480809 14 241032 1131481137 15 241055 1131482644 16 241038 1131481530 17 241078 1131484152 18 241025 1131480678 19 241030 1131481006 20 241037 1131481465 21 241040 1131481661 22 241023 1131480547 23 241053 1131482513 24 241041 1131481727 25 241077 1131484086

  12. Hello everyone, I need to modify furnace ladder diagram to take control of the upper PID limit. The temperature on the furnace is controlled using PID. There is master PLC CJ1GCPU45SP which communicates several slaves CJ1MCPU13. It looks that all the PID parameters are send from the master to slaves over DeviceNet using seven DRM21 modules installed on extension rack. I can see where the values for the PID are entered on the HMI and moved to new location in the master but I don't understand why they are not placed in memory locations used by DeviceNet by default as per DRM-21 manual ( which if I understand correctly are D30000 to D31599). Is it because the DRM21 are mounted on extension rack? I will list all the upper limit locations in master, it is a long list but hopefully will help in resolving this issue: HMI entry location Moved to location in the ladder D16401 __________________ D32023 D16403 __________________ D32047 D16405 __________________ D32071 D16407 __________________ D32095 D16409 __________________ D32323 D16411 __________________ D32347 D16413 __________________ D32371 D16415 __________________ D32395 D16417 __________________ D32623 D16419 __________________ D32647 D16421 __________________ D32671 D16423 __________________ D32695 D16425 __________________ D29923 D16427 __________________ D29947 D16428 __________________ D31723 D16429 __________________ D31756 D16430 __________________ D31757 D16431 __________________ D31758 After they are moved to the D3xxxx location they are not used anymore anywhere in the master PLC so I am assuming they are transmitted over to be used in slaves. Is my reasoning correct? How can I calculate address space used by each DRM-21 card to make sure I am understanding what is transferred where? Thank you.

  13. CJ1W-TC001 PID question

    python01 posted a topic in CX-Programmer

    What is Omron naming convention for PID settings? I need to adjust the upper MV limits for PID running on CJ1W-TC001 installed on CJ1M-CPU13. Looking at the CJ1W-TC001 Operation Manual I am not really sure which values would these be. I guess Omron naming nomenclature is a bit different than what I am used to. It seems that the Manipulated Value Monitor is just feedback, which value would I need to set or modify to adjust the upper MV limit?

  14. Built-in Ethernet vs QJ71E71 Module

    valsidalv posted a topic in Mitsubishi

    This is my company's first time using a Mitsubishi PLC and our partners/clients advised us against using the built-in Ethernet port on the Q03UDE CPU, saying that we should instead use a standalone QJ71E71 Ethernet module. The QJ71E71 costs 1.5x the CPU module so there are significant savings in using the built-in Ethernet. They cited reliability issues but can anyone here back up their claim? We use our PLCs as simple I/O blocks - a PC runs a program which communicates with the PLC and tells it what outputs to fire. There is no actual ladder logic on the PLC. The PC connects directly to the PLC. I wrote a small C# utility that blasts the QX40 and QY80 input/output cards on my stack with random values and reads them back to ensure correct data transfer. The QJ71E71 Ethernet module averages 10 ms for a read or write operation and the Q03UDE averages 3 or 4 ms (much quicker!). So, does anyone have a reason to use the QJ71E71 port instead of the CPU? Thanks
  15. Hello, I have an annoying problem with communication between Siemens S7 PLC and HMI panel. Here it how it looks like: I am using Siemens S7-315 with 343 Lean ethernet port. This port is used to communication with HMI terminal. Communication is realized through S7-TCP communication protocol. When I was testing the communication in the office everything worked fine and nothing wrong happened. The problem occururs only on the installation. After turning the PLC and HMI on everyting works fine, data is transferred correctly and variables are displyed on HMI. After a few hours the communication is suddenly lost. This is a direct connection between PLC and HMI and there are no other devices in this network. So it is not possible that suddenly there is an address confilct. I made a wireshark analysis (I connected a notebook and hub into the network) and I found out that when the communication is lost HMI terminal is trying to get data from the PLC but it is not responding. It looks like PLC ethernet port is broken. You cannot ping PLC from notebook and HMI. On the other hand you can exchange pings between HMI and notebook. The communication is back again only if you'll restart the PLC. The strangest thing is that I did not have any problem with the communication when I was testing it in the office. The configuration and project of PLC and HMI is excactly the same. The only difference is that on the installation PLC is realizing also a communication throguh Profibus and MPI. I've tried to use different ethernet cables (crossed, non-crossed) but in all cases the situation is the same. Do you know waht can be the cause of such behavoiur? Maybe someone had a similar situaion? In the attachment I send a screenshot from Wireshark which shows the moment when the communication breaks.

  16. Cimplicity 8.0 Alarming

    lchamarthi posted a topic in GE

    Hi Guys, I am new to Cimplicity SCADA but I was familiar with HMI. Now my requirement is to separate / dedicate the alarms to each process or setup in the respective screen. Prior they have made all alarms to fire on all screens/ all process. Now idea to separate the alarms in the respective screen. In all screens on top, if I click on alarm object, its properties are Link Container and it has Link source file as xxx.cim and Link source Object as Alarm. Please guide me from the beginning, how they configured the existing alarms also I am not understanding. I need help please. Thanks a lot.
  17. Currently we have a remote I/O module to connect with our PLC, yet it's not showing up whenever we try to connect it via inside RS logix 5000.

  18. Control G120C via Profibus

    Bryll posted a topic in Siemens

    I'm trying to control the speed of a G120C via profibus, but it will trip out when any changes are done to the speed value. The unit was commissioned by another guy, and he doesn't have a clue where to look. We can start and stop the unit, but it will stop at any attempt to change the speed. I was told to look for a parameter allowing it to be controlled remotely, but wich one is it ? As usual when it comes to Siemens, the manual sucks. I'm using a function block for controlling the drives (13), and the older 12 is responding correctly to any change. Anyone here that has a clue what parameter to change ?
  19. Hello All, I want to read data from a Control Logix PLC, into a PLC5/60, using Ethernet and a MSG instruction in the PLC5. When verifying the MSG instruction in the PLC5, I get an error message. "Target Address in invalid". Once I figure out how to do this I need to replicate it in another PLC5. Scope is to read the status of 4 paint pumps controlled by the CLX. If any of the 4 stop, the PLC5 needs to know, because it is controlling the paint application equipment. Source data resides in a Control Logix 1756-L63. The tag is INT type, 4 elements long, and the name is PUMP_STS_B2. The IP address of the CLX is 4.2.6.230. There are 2 ENBT cards, one in slot 1, and the other in slot 3. 4.2.6.230 is slot 3. PLC2,5 / SLC Mapping has been created in the CLX. File=421 Name PUMP_STS_B1 and File=422 Name Pump_STS_B2. The file mappings represent a binary file created in each of the PLC5's B421:0~4 in Booth 1, and B422:0~4 in Booth 2. The PLC5/60 is Enhanced series E model using the Ethernet side card. The IP address of the PLC5 is 3.26.5.61. I also created MG file types in each of the PLC5/60. MG420:0~19 in each processor. This was necessary to use the MSG instruction in the PLC5. I have searched the forums for examples of how to do this with no solid results. I am trying to follow the best practices of reading the data into my PLC so anyone who follows can tell where it is coming from. While the IP addresses are not closely related they should be able to communicate. I say this because all of our PC's are on the 4.2.6.XXX network on a 255.255.252.0 sub net and we have no issue communicating with the 3.26.5.61 IP address. Any help and advice would be greatly appreciated. Regards, Mike Carter

  22. Hi Good Day, I need a suggestion, I have an omron encoder, encoder counter meter (K3NC-NB1A) and communication card RS-232C 25pins (K31-FLK1). My question is, what is the best omron software to read and manipulate the data from the encoder (I have CX-one software but I only use CX-programmer). I want to capture the encoder pulse and convert to velocity, acceleration, deceleration and also energy absorbtion. I have to use mathematical formula such as two times differentiation. I also need to show grapf and display final result that is energy absorbtion reading. Or is it much simple if I use VB / labview / java software? Thank you in advance

  23. Connect OMRON CJ1H to GSM modem

    AlexCyril posted a topic in CX-Programmer

    Hello guys, actually I am new to this Omron PLC. but i have small project to transmit a command to the GSM modem via the RS232 port so it can trigger the modem to send text msg. Can you show me the steps/guide/sample program to accomplish this program coding? I already read some topic in this forum regarding to this PLC RS232 port but still cant get the ideas when to create the ladder program. PLC Type : CJ1H (CPU65H) - RS232 port First input to trigger the GSM send text msg: AT+CMGS="+YOUR HP NUMBER" Second input to trigger GSM send text msg: YOUR TEXT MSG CONTAINS (Ctrl+z to send) Many Thanks, AlexB
  24. I'm having a bit of difficulty with the MSG function on a logix5000. I'm simply trying to get a REAL value ("BH5_Flow") out of another logix5000 and assign it to a tag in the PLC. I've created a MSG function and created a new tag "BH_5_Flow_MSG" for the message, and created "BH5_Flow_M" for the value that will come from the MSG function. When I click the "..." button to bring up the config, I put the following in: Message Type: CIP Data Table ReadSource Element: BH5_FLOWNumber Of Elements: 1Destination Element: BH5_FLOW_MIn the PATH tab, i then put the following in: Path: LocalENB, 2, [iP ADDRESS OF SOURCE MACHINE]When I test the edits, I then get the ERR bit activate with error 16#0004 when the message rung runs. Anyone got any ideas where Im going wrong? I've practically copied another MSG instruction from further up the ladder but it doesn't seem to work
  25. Hi. I have a ST-Lite Ethernet base (STL-ETH1) with 1 16 bit digital in card, 3 digital out cards, 2 analog in and 2 analog out cards. I have a Q03UDE CPU (Q PLC) with 1 16bit digital in and 1 digital out card. Now I like to setup the remote I/O (STL-ETH1) mapped to the Q PLC via the ethernet port on the CPU. Is it possible not to use Modbus at all. I don't want to go and buy a Modbus Ethernet card now. Have someone done this before?
