  1. 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.
  2. CPU 314IFM adress

    Hi, I have a CPU 314IFM order number 6ES7 314-5AE10-0AB0 when i select it in hardware config it show I/Q adress 124 -155 while it should be to 129 only (the manual mention that and it covers all inputs and outputs and the special funaction also) I try (offline) to change the order number only (another 314IFM) found it give different address range for each CPU while it all have 20 DI/16DO 4AI and 1AO
  3. 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
  4. Hello all, I'm new to this forum, hope I will be able to get some answers on this forum. I'm wotking on maintanance for machines under productiona and I would like to conect one machine to my work PC. But when I try to setup conection with RSLinx, RSLinx don't see my PLC. Problem is that my PC is on network with IP addresses 192.168.8.XXX and machine is on 192.168.0.1 IP address and between is cisco RV180 routher which is set to have LAN address 192.168.8.168 (company network), and WAN is set as 192.168.0.200 (subnet 255.255.255.0, gateway 192.168.0.201, dns 192.168.0.202). When I conect directly 1756 ENBT/A card to my laptop (laptop is set to same range of IP addresses) I can see PLC and everything is working but this way is not practical for me. Is there any way to conect my office PC to PLC, some settings in RSLinx Clasic? Any idea would be helpful. I attached simplified network drawing for easyer understanding. network.pdf Thank you for your time and help, best regards, baric1007
  5. 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.
  6. Hello everybody, I am connecting my DCS digital output (115VAC) to AB PowerFlex 753 Digital Input. We are using the 20-750-2262D-2R I/O option in the powerflex which is 115VAC I/O with 2 Analog In, 2 Analog Out, 6 Digital In and 2 Relay Outputs. My question is, what is the current or power consumption of the PowerFlex DIs at 115VAC. I need to specify the right fuse size for my digital output. Thanks,

    Anyone know how to read a program of KV 40 with protection MEMSW $ 8,000. It's an old ladder diagram I want to retrieve. I've seen this link which talks Pseudo reading it. Link http://forums.mrplc.com/index.php?showtopic=6782 Thanks, Ágora
  8. Control G120C via Profibus

    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 ?
  9. I'm new to Omron, and after several days of diving into manuals trying to figure this out on my own and giving myself a headache I've come to accept that i need help. my task is the following: Control of the discrete and analog inputs/outputs in a DeviceNet system using an Omron CJ1M PLC’s and PT’s. Use at least one thermocouple, one analog input, and one analog output for the DeviceNet network. Use a pushbutton and a light for the start of the process and an indicator for the started process. I have a Drt1-Ad04 input, a Drt1-ad02 output, and a Drt1-ts04t temperature control. My devicenet is Cj1w-drm21, The Omron system itself is a cj1m-cpu13 etn21. I have node addresses for my input, outputs and temperature control, those being 35 for input, 25 or 30 for output and for temperature control 5, 15, or 20. The ip address im using for this project is 142.214.143.9I'm using Cx programmer, Designer and Integrator. On Cx programmer I've managed to create an IO table but i have no idea on how to begin the program or even get a current reading from my generator.On Designer I've made what i believe to be the layout of the pushbuttons, I just have no idea of what addresses to enter.And on integrator i'm having troubles on figuring out how to make a routing table. I've went through many manuals and either i'm missing something really basic here or I just have no idea on what I'm doing. The only advice I was given was to dive into more manuals and find my addresses for my inputs, outputs, and temperature or to find the information from an outside source be that a forum or customer service. I am able to provide more information, and screenshots of what I have done if needed. Any kind of help would be greatly appreciated!
  10. For "string display and input" objects, there a "full keyboard" option that, when selected, will cause a keyboard screen to pop-up when you press on the input object. Is it possible to change this keyboard to one with Russian characters on it?
  11. I am trying to setup communication between an EIP21 and a AB Compactlogix processor. Setup both units with Network configurator and Logix5000. In Logix5000 I used the Generic Ethernet Module with the correct consumer and producer tags and instances. When I go online Logix can see the EIP and bring up the module information but the connection itself is in Error 16#0114 Electronic keying Error. Unfortunately cannot find a way to disable keying like possible on the Controllogix Ethernet module. Can Anyone help. An application example or some tips how to resolve it would be great. Kind Regards Rolf
  12. 1747-AENTR

    Hello, would like to change some ideas with you. I´m working in a new project and need convert an SLC500 to Controllogix, with a 1747-AENTR is possible create a SLC500 Eth remote.... but in my case i have two 1746-A13 (conected by expansor) and can´t add all the modules in a rslogix5000 aplication. In the 1747-AENTR manual say that is possible in the v21.00 of the rslogix5000... I really need install this new version? Don´t have other way? Thank you! Vitor Prado

  15. 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
  16. Connect OMRON CJ1H to GSM modem

    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
  17. 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?
  18. I am working on Remote IO panel and plan to use the following components: 1734-AENT 1734-OW4 - qty 2 1734-IE4C I wonder if I need to separate the bus between the relay output module and analog input module? Or anywhere else in this setup? Thanks.
  19. I have 4 Allen Bradley PLCs which are 3 SLCs and 1 CLX This PLCs need to send data to Yokogawa Centum VP DCS. Instead of having and individual Modbus link to DCS, I'm planning to link all 4 PLCs by using Ethernet/IP and plan to buy 1 extra mini PLC which is Micrologix 1400 to become an interface PLC between the 4 PLCs and the DCS. Since the Micrologix 1400 has embedded with an Ethernet port (Ethernet/IP) and Rs485 port for Modbus RTU, the Micrologix 1400 interface PLC will communicate with DCS using Modbus RTU Protocol. Meaning to say, the 4 PLCS will send data to the Yokogawa DCS via interface PLC. The Interface PLC will become translator to translate from Ethernet/IP language to Modbus RTU language. My question to Expert: 1. Is this setup can works? 2. How to send data inter-PLC by using Ethernet /ip ? Is it just need to grab the tagname or there is an address for that? 3.Is Micrologix is capable to communicate with 4 PLCs using Ethernet/IP? Or just only 1 PLC? See the attached photo. Thanks. -Nizam-

  22. Hello, I'm working with some old Allen-Bradley SLC5/04 systems with 1747-SN modules. The module is located in Slot1. One system is only using the RIO module for a PV1000. How do you know where the "M-Files" for Analog I/O modules and/or Panelviews are located? I see programming using locations such as: M1:1.810 where 60 words are being copied from a Remote I/O PV1000 to some words for the SLC to utilize, but I don't understand why "M1:1.810" was used instead of, for example, "M1:1.800"? I looked and so far cannot find information pertaining to the words other than what is in the User's manual, and it doesn't address this issue. The panelview in my example uses all of Logical Rack 0, Full Rack addressing. Any help would be most appreciated. I have very little experience with the RIO stuff because almost everything I've worked with in the past has been Devicenet.
  23. Using GX Works 2

    Hi all, Just joined today and was browsing through this forum. Now I need advice/help. I have installed the software to read an FX PLC. It worked okay yesterday. I was going through a program printout that I downloaded and couldn't see where the X inputs were in the program. So, I thought i'd go back in and get the program again. I connect to the FX fine. It passes the test and then I connect. The screen comes up entitled "Online Data Operation". I select "All" and hit the execute button. Wait about five seconds and then I get an error: "The Device Data Name is Empty". Okay. I go to put a name on the "Title" box and it WILL NOT TAKE KEYSTROKES. Gaack! :helpme: I have restarted the program and laptop several times. No matter what i do it will take keystrokes in the "Title" bar. I cannot get the program. Any thought? The only thing I can think of is to reload the program but that takes quite a while. Old stuff is fun to work on.
  24. Inverters on Profibus

    Hello, Tried to get some good and clear answers at the Siemens forum, decided to try here aswell. I have a setup with 12 G120C inverters and three gas burner units on a profibus line. If I unplug any of the devices will I of course get an error from the loaded OB. But, now and then can I lose the connection to two or more of the inverters without any notification. It seems that the communication is up and running, but the don't respond to any commands. The normally green LED on the inverters switch over to flashing red when they stop to respond. They will also show fault code 1910. I am using standard telegram 20, this is also set in the inverters parameter lists. Another funny thing is that the fault bit in the status word is always set. Even when the inverters don't hav any faults or alarms. ZSW looks like this (with or without response from the inverter): Bit 0 = 1 (Ready for switching on) Bit 1 = 1 (Ready for operation) Bit 2 = 0 (Running) Bit 3 = 1 (Fault) On all the time, even when there is no faults in the inverter Bit 4 = 0 (No coast down active) Bit 5 = 1 (No fast stop active) Bit 6 = 1 (Switching on inhibited active) Bit 7 = 0 (Alarm present) Bit 8 = 1 (Speed setpoint - actual value deviation within tolerance) Bit 9 = 0 (Control requested) Bit A = 0 (f or n comparison value reached) Bit B = 0 (I, M or P limit not reached) Bit C = 1 (Reserved) Bit D = 1 (No motor overtemperature alarm) Bit E = 0 (Direction of motor rotation) Bit F = 0 (Display CDS) Anything I might have missed or done wrong ?
