  3. Hey all,  So I am looking for some assistance because I am not understanding how the tags on an HMI and within a PLC are linked. There are no 'physical' buttons, just what is on the HMI. It is controlling a chiller. Communicates over Modbus TCP/IP. The PLC is an IDEC. I have some-what worked out how other tags are working when they are words being passed back and forth, but this one has me stumped. I've attached a few screenshots for referral. It looks like the run and unload buttons for the chiller are a single bit/BOOL toggle (but the chiller running latches itself in the PLC when the chiller starts to run). The stop buttons appears to be a parent for the single bit/BOOLs and when it is pressed it resets them all both on the HMI side and within the PLC side.  
  4. Hi there, I have a controller NX1P2-1140DT. I want to control a VFD with modbus serial communication. Can someone help me start from scratch ?
  5. CX-8190-Modbus Srv

    Hey guys, I am trying to communicate between a Beckhoff CX-8190 & a third party fieldbus module that supports Modbus TCP, now I am able to write/read to the fieldbus when twincat is running on the local machine (laptop), but when ever I connect to the device and run the same function block it doesn't write nor read to the fieldbus. I am assuming that the modbus server has something to do with it, so is there a way I can install it to the plc ?
  6. KINCO PLC as MODBUS RTU slave

    Hello to everyone. I hope you are doing well. I'm trying to establish a communication between my PC and my KINCO PLC. The manual states it supports MODBUS RTU protocol, so I downloaded two different Modbus Master simulator I found out: Multiway from OMRON and qModMaster. None of them seem to work properly. I attached some pictures of the messages I get. https://ibb.co/f1mCSNt Multiway message https://ibb.co/bP5cX1t qModMaster message I include the configuration of the communication parameters. https://ibb.co/nMty8D9 PLC parameters https://ibb.co/6RTqVfC Multiway parameters https://ibb.co/N1XTccd qModMaster parameters According to the manual, in order to play the role of Modbus master with the PLC it's necessary to configure some instruction blocks (I'm programming in ladder). However, I could not find any block to configure as Modbus slave. I don't know what else I can do. I'm in trouble with this task. Am I making some mistake? Thanks for your attention.  Kind regards!

  8. GX works 2 software

    Hi guys    I am having trouble installing GX works 2 software. The software is fully legit and came with 2 license keys the first one I put on work laptop and second on my personal laptop. The install all goes fine but when i try open up GX  Works 2 I get this message from the attached image. I have plenty of room on my pc and even have other PLC from different manufacturers on it without issue but the GX Works is just giving me grief and I have tried to increase data on MY laptop and other windows fixes but still get this message when I try open it.  Has anyone else encountered this problem before or any ideas?   Cheers guys

  10. Hi all, I have an application where two buttons are created: End Batch: "Momentary Push Button" that modifies the value of a tag. Print Report: "Display Print Button" that generates PDF with a screenshot of the current screen. I would like to mix both buttons into one single button that does this functionality at once. I have been reviewing forums and it seems that the only way to do that would be by using VBA code but I believe that this is not available on FactoryTalk View ME but only on SE. Would anyone know a way of printing a PDF screenshot + modifying a tag at the same time and with a single button on FactoryTalk View ME? Thank you!
  11. 1756-RM2 Event Log error

    Good day,  I retreived the event log from 2x RM's today, I found on the one RM that there has been more than 700 million events. Apart from switchover events, there following event shows up a lot: (C2) Bridge Connection Deleted       Starts/Stops   Byte 1 (0xFF) : Byte 2 (0xFF) : Byte 3 (0xF2) : Byte 4 (0x13) : Byte 5 (0x0) : Byte 6 (0x0) :  Our system: 1756-RM2 1756-L75 1756-CN2R 1756-EN2TR 1756-EN2TR 1756-EN2TR 1756-EN2TR The CN2R's are connected to 12x 1771-ACN15 and 2x 1756-CN2R in remote racks, which is also set up to be the keepers. The EN2TR's are connected to their respective ETAPs/EN2TR's in ring topology.   We have experienced some issues when switching over. Hope someone can tell me what that message means regarding the Bridge Connection.    
  12. Redundancy Error

    Hi everyone... I'm not a AB expert.. I'm using L74 controller, Rm2 redenduncy module,  EN2TR and EN2T module (on each chassis) on my control logix project and having 3 remote IO's rack on ring topology... I have use EN2TR for ring topology and EN2T for scada communication. The problem is my controllers are not synchronising on fibre optics... I have to connect both EN2T modules with one an other for controller's synchronisation. They are syncing over ethernet but not over optical... your help is appreciated    Thanks in advance
  13. Quick Designer Software

    I am looking for a working copy of software that will work to modify screens on an old Quick Panel.  I believe the software is called Quick Designer. The old Panel I am trying to access is serial communication only. I have bought an interface cable from PLC Trainer.  I have a Windows 7  32 bit machine ready to go. Thanks, Scot
  14. Serial communication with KINCO PLC

    Hello to everyone. Nice to meet you all. I am programming a KINCO PLC model HP043-20DT using ladder on KINCO BUILDER. I need to establish a serial communication with my PC. The PLC has a RS485 port which I adapted it to USB to connect with my PC. The PLC allows, at least, two ways to establish serial communication: MODBUS or free-protocol. I've read the software manual and tried to reproduce the examples it provides using the instruction blocks for MODBUS (MBUSR and MBUSW) and free-protocol (XMT and RCV) communications. However, I could not receive the data on the PLC. I could effectively transmit data with XMT from the PLC to the PC and I could verify through a tool called Access Port. In relation to MODBUS, I am using a simulation tool called Multiway from OMRON, however, I get no response from the PLC. If any of you have some experience with this software or this device, I would like to ask you how could I solve the problem. Thank you for your attention. Kind regards.
  15. EPLAN Help

    I am attempting to use EPLAN P8 (v.2.9) to import details from a 'holy grail' excel sheet of a cable list with terminal tags and numbers (source and target for each cable). To do this I began importing details in a trial and error fashion through the pre-planning menu to the pre-planning navigator. I have several questions. Question (1) Has anyone else tried to do this?  In the process of importing from the excel sheet I have not been able to successfully assign source and target for each cable object. It shows up on the synchronization dialog after I work through the field assignment but it disappears after import. ( I do not fully understand the proper structures, definitions, properties and levels to get what I want). I do understand if I import source and target terminals, and cable objects separately, then I can place on the detailed view and source and target are assigned then. Question (2) Does anyone know how to assign source and target to a cable object in pre-planning 'by import'?  (Reason being that the excel file is huge and manual assigning isn't feasible). On one of my attempted field assignment schemes I was able to have cable, source terminal, and target terminal, all on different levels (not actually assigned as source and target for the cable object btw.). However the result for source and target on the report (planning overview, form: f40_006) had all of the designations of the tree structure from the upper levels. For example, cable: HAC4401, source: HAC4401 X1:5, target: HAC4401 X1:5 TB1:5. (Where X1:5 is source terminal and TB1:5 is target terminal). Question (3) Does anyone know how to create a 'branch' or 'fork' in the tree structure in the preplanning navigator so that both source and target terminals (planning objects) are on the same level and so do not inherit each others details?  There's a bunch of info in reading the above I know, but if anyone can shed some light on this it would be much appreciated!!!! Thanks in advance,  MajorMac
  16. Hello everyone    I am working on modbus TCP protocols to communicate between SEW drive and Omron PLC CP1L-EM. I am following modbus TCP function block from Omron, But i have updated that block because of is not fit to SEW modbus communication. Currently, I am sending a control work to SEW but I am getting error on Modbus TCP from SEW drive, which is invalid data. So I am looking your help is you work with SEW drive before and communicate over modbus, then please let me know how to make a data string for read and write (SEW Drive function 23). I am using 3PD data structure.    Thank you

  18. Powerflex 400 25HP wird amp behavior

    ello I have a powerflex 400 of 25HP for a 60amp 25HP motor, the motor have a belt that move the clarifier of milk. It is a process that requires strength to move.So I try with the motor without the clarifier the vdf works well with a constant amp of 12 to the max of 50hz that is set up with a ramp of 600 sec.Then I try with the belt that move the clarifier... The vdf start the ramp with a wird amp behavior like 10 sec 100 amp and then 13 amp for 10 sec.When it gets to 50hz (the max) it starts the same behavior 13 amp when it reach the max RPM and when it decrease a little bit it gets 100 amp to get to the max RPM again.In this vdf powerflex 400 I didn't see the % of torque options that the last one Fuji had.Someone told me that powerflex 400 is not for power processed, they are focus in pumps and blowers more alike, and that I need a vdf vectorial like a powerflex 725.What do you think...PD: as the 100 amp is like 10 sec the protections dont show up. PD: I made a try with water and hot water, in that point with the max hz  (and 6800rpm) when the hot water start to flow the amp gets constant in 75 amp, but the motor dosnt get to the 6800 rpm again it just keep trying in 6700rpm and it mantains the 75amp triggering the motor protection for overload.
  19. Good day everyone, First post here so hopefully I'm not violating community guidelines in anyway. I've got a system that has some 50 odd Micrologix 1100 and 1400 in use and I'm currently working on setting up an auto timesync for all of them using just 1 of the PLCs that will be my master time PLC. So far I've put together the logic for all the message instructions with the corresponding IP of the slave devices. I'm running. Into an issue with not being able to terminate/break the message connection on a PLC that I have already synced. Is this even possible to do on the ML1100. Once I get to 16-17 messages DN it starts to ER and will not complete any further messages. What I have is a message instruction ladder with a timed trigger to activate a MSG and write the RTC data then time down and connect and write to the next and so on. When it triggers the message instruction of one PLC it also fires an OTE to trigger the BK of the previous message instruction. However it doesn't seem to be actually cutting the message connection and holds it persistent until a power cycle/download event.
  20. Hi,  We have 2 x 1756-L71 Processors joined together with a pair of 1756-RM2/A redundancy modules. The rack also has 1756-EN2T and 1756-CN2R modules.    I was called to the site after a power outage and found that the link between the 2 CPUs had failed with one displaying no program and the link modules with error lights. The ControlNet cards also had red lights on both channels and all of the FlexIO devices were red Xed in RSLinx. I went down the path of trying to get the CPUs up, and running but this was a red herring as I was informed that if the CPU's get out of Sync and have any faults on the cards the secondary one will lose its project. The ControlNet cards were giving a no Active Keeper fault? So we went down the path of the ControlNet cards, I initially thought that it was that the cards had lost their configuration files but we isolated the coax network to just the 2 cards, and the CP's and ControlNet cards came back up online. We joined the network back onto the ControlNet cards and found a faulty 1794-ACNR15/CFlexIO module. Once we replaced this the other devices (48 devices on the network) were not being discovered on the network. We went around and power cycled the IO units and then they started to Auto discover and the site came back up - Note CPUs were in Program mode at the time and I flicked them to Run and the site came back online. Does anyone have any information on why they needed to be power cycled and is there likely to be an underlying issue other than the single failed module pulling the network down?
  21. need SLC Logistics Revision 2.09

    I have some files from an SLC 150 that I need to recover the logic from. The problem is that I do not have the .150 files(to use PCIS.EXE). the files I have are .SLR,.SLT,.SLX,.SLC,.SLD.SLF,.SLP file types. From my research, these files are meant to work with a program called  SLC Logistics. I need to get a copy of this program if someone can send it to me. I am interested with anyone who knows how to pull the PLC logic from these file types.   I have used the utility SLC2DB to convert the rung,bit, and page files. This helped but it basically just got me the documentation. I still need to get the logic. you can see my other post here https://forums.mrplc.com/index.php?/topic/41174-slc-150-program-read-need-pcisexe/
  22. How long  could be INT array. For example can I build INT[365] or DINT[365]? When I use more than [32] my controller fails. Thanks. 
  23. Hello, I'm using View Designer 7.01 and experience anomalies in project explorer. When I move mouse cursor over project explorer, highlighted lines render with anomalies. I have tried to create new project with different HMI and  and versions, but it didn't help. (picture in attachment) Anybody experience this problem before? Thanks in advance! Scotty
  24. Hi everyone, I'm new here. Thank you all in advance for the help you can give me. I have one machine with PLC Omron NJ101-9000, and this is Server in the Modbus communication. In the attachments, you can find the function block I used to communicate with 1 client. This work OK and I don't have problems, but I need to communicate with 2 clients at the same time. This block only admits one connection at a time. How I can connect 2 at a time? If I create 2 of these blocks, does each client need to connect to a different port? Do I need "open" this port in PLC configuration?   Thanks!
  25. Hardware IQ-F connected via Modbus TCP on the NZ2FT-MT works Fine with normal IO. Now i want to run the NZ2FT-C24 with an modbus RTU protocol, i'm planning to make this. Anyone having an example for the NZ2FT-C24, what can help me?
