  1. Hello,  I am working on a project to connect a PLC (Micro820 by Allen Bradley) to a simple RS-232 alphanumeric OLED display. I am not too familiar with structured text language, but I have worked with micro-controllers that use similar high-level languages (mostly C-based).  My question is: is it possible to use connected components workbench to program my Micro820 to output ASCII commands to an off-the-shelf RS-232 alphanumeric display? Are there libraries that make life easier to do this?  I welcome any recommendations to related reference material or command tutorials, thanks!

  2. Mitsubishi iQ-R Series

    CementMatt posted a topic in Mitsubishi

    Hi Has anyone got any real life experience with the new Mitsubishi iQ-R series?  I have been assigned a major capital project to replace our old ageing DCS system.  Our current PLC backbone is about 40x Q2ASHCPU, 10x Q06UDEHCPU and about 2xA2SCPU all linked up via Melsecnet/10 network with communication links into the DCS system via Modbus RTU utilising the QJ71MB91 modbus card. Due to the nature of my companies process and the limitations on plant downtime it is estimated this project could take up to 5 years to complete, with this in mind I am wanting to install a system that will not be obsolete (or unsupported) in a few years, hence, I am very interested in the new iQ-R series with it being Mitsubishi's latest and greatest.  However, recent communications with my local Mitsi rep is not filling me with confidence that the iQ-R series is not as well supported/developed as the Q series.  A major requirement during the development stages of this project is the new ability of the new processors to be able to talk to the old DCS up until a point where the DCS nodes will be completed removed and replaced with a modern SCADA package.  Hence, the requirement of a Modbus Slave card for the iQ-R (i.e. a QJ71MB91 equivalent) which I am told is in development, but has no fixed timescales.  Previous experience with Mitsubishi developments of cards is normally years not months. Any information anyone can provide on their experience of the iQ-R series would be greatly appreciated and if anyone knows if a Modbus Slave card is in development that would be useful.  I realise i could utilise the Q series extension rack with a iQ-R processor but this is not the route i want to go down. Thanks for any help and apologises for the war and peace. Cheers Matt

  3. Beckhoff and AS-Interface

    karim_ posted a topic in Other PLCs

    Hi, I’m trying to control 10 Safety switchgear using AS interface, and since I’m using Beckhoff as a PLC I want to use "KL6211 | AS-Interface master terminal" as a Gateway but since this is the first time I’m using Beckhoff I’m a bit lost, So my questions are: -          Is it a good idea to use a Beckhoff ASI terminal? -          How to configure it? -          Is there a possibility to configure it using embedded PC ( I’m using CX2030)? Excuse my English.

  4. Logo!8 sensor compatibility/display

    CaitNCSU posted a topic in Siemens

    Hi there,  I am brand new to the world of PLCs. I'm working on a project and we will be using the LOGO! 8. We will be monitoring a tractor's ground speed, wheel speed, (wheel slip using those two), oil pressure, tachometer, EGT, and system voltage.  As I said, I'm brand new to all of these things. Any tips or advice to get started? Or things to avoid? Specifically when choosing sensors. Also, we were thinking of a tablet to display these measurements in real time. Any suggestions? I was thinking the Simatic HMI touchscreen may be a better option for compatibility. This will be on a competition tractor, though. From experience, how durable/rugged are these displays? It would mostly be subjected to dirt, vibrations, and quick jerks.  Any advice to help guide my Googling adventures would be greatly appreciated!  Thank you.

  5. Master/Slave Communication

    MZohaib92 posted a topic in Other PLCs

    Hello guys, I am using Fatek PLC's to communicate with each other as a Master & Slave through zigbee which is connected through RS485. And I succeed. But the issue is that I have to communicate each other at a distance of about 2km where zigbee out of range to each other. I am bit confused here; 1) whether I use RF booster? Does it work? 2) Should I introduce extra PLC as a repeater between master slave? But this(extra added) PLC repeater also become as a master(Master Repeater).or any idea? Most important I can using Fatek Protocol or Modbus RTU or Modbus ASCII prootcol.

  11. E1151 New Display Register

    Graham posted a topic in Mitsubishi

    Hi all, I wonder if anyone can help me. I have 4 test rigs setup with E1151 HMIs and FX3U PLCs (with two ADCs and one DAC).  They are running pretty well, and the HMI changes block fine when using Jump to Block, but when I try to get the PLC to change the HMI's block using the New Display Reg it becomes very temperamental. For automatic testing I want the PLC to prompt the HMI to change block, so I set it up with a PLC register, then set the HMI to use this register for the New display reg.  When I turn the PLC and HMI on I can run through the test, and at the end it changes screen perfectly.  However if I run the test again the HMI appears to "forget" to change screen.  I have checked the new display register and It lists the correct screen, but the HMI doesn't change. So far I have tried adding "SCRR" too the command list to use short recipe names (saw this on a previous post), and tried reducing the amount to data transfer between the HMI and PLC to see if it was a latency issue, but neither have worked. Has anyone else witnessed problems like this?

  13. Hey Guys,i'm working on implementing the master side of a custom serial master-slave protocol between a B&R PLC and an electronic card.As part of the data i'm sending and receiving is used to close various loops(e.g. cascaded temperature control where the temperature sensors and actuators are connected to the electronic card) , but other data is not as usefull (e.g. various data used for display or at specific times), i believe i will also need to implement some sort of priority mechanism.my first question is - based on your experience - how would the general master side SW architecture look like? (for example - the send side of mine is comprised of 3 tasks all running under the same cycle - lower level task in charge of opening the port, sending the data etc, a mid level task in charge of creating the packet based on command from upper level, giving commands to lower level and using status from it to continue and finally - an upper level task in charge of deciding which messages to send).my second question is - how would you implement the priority mechanism?thanks

  14. NB Display MASTER SLAVE

    manowar posted a topic in Other Omron Software

    Hello.   I have a question regarding NB series display. The comunication is made through RS232 / RS485 comunication. I would like to use NB display as MODBUS MASTER and SLAVE aplication. - Display would work as MADBUS-MOSTER to talk to plc controllers. (Working through COM2 - RS485) - Secondly, Display would work as MODBUS-SLAVE to talk with (SCADA). (Working – Registers LW, LB))   What I have trouble with, is: - I would like to change variable in the PLC - for example : Regime_PUMP (address: 0x0001). - Regime_PUMP variable should be settable from all three devices PLC <-> DISPLAY <-> SCADA So: - If I change Regime_PUMP through PLC it should refresh also on DISPLAY and SCADA. - If I change Regime_PUMP through DISPLAY it should refresh also on PLC and SCADA. - If I change Regime_PUMP through SCADA it should refresh also on DISPLAY and PLC.   Does anybody have an example for NB series of display to do this?   Best regards.
  15. I am running a very large step based program on an NJ plc.  I have several status and alarm messages that I need to display on the screen during the auto cycle.  Right now I have set up unions in the PLC for the faults... but this is a very large program with a lot of possible faults.  I'm up to 9 16-bit array unions already.  It is just getting really cumbersome.   I would like to just write an INT to a data area for each fault and status message.  That way I can assign each step a 5 values to be used for faults and messages (ie: step one can use numbers 1-5, step 2 can use 6-10, etc) .  Then I want to have the NS display a message from the string table based on the value in the data area.  Is this possible?
  16. I am working on project which is using Micrologix 1400 and AB Panelview. I am using FactoryTalk View Studio to build the HMI. The PLC needs to know which screen is displayed on HMI so some additional functionality can be activated. How would this be done? I was looking where could I write screen number to N7 location in the PLC or set a bit in B3 area but could not find anything. Thanks for your help.

  17. CP1E MODBUS Maximum Slave

    innoaloe posted a topic in Omron

    Hello everyone, so I noticed in Omron's CP1E manual, there are no certain info on maximum number of Modbus Slaves that can be attached, however the PLC itself able to connect to slave number 1 - 247 I have read from common MODBUS specs, that 32 slaves are the limit for most MODBUS connections. However there are also statements that with proper design (1/8 transceivers) that we can extend number of connected slaves to 256. Anyone have experience or info about this with Omron PLC? Thanks in advance

  18. GE iFIX iClient - Mutiple Display

    JustMe posted a topic in GE

    We are getting a new HMI system that will be running on GE iFIX and iClients.  The HMI is designed for a single monitor (1920x1080) and this will be displayed on a system that can support duel monitors.  We would like to use the second monitor for other windows based applications but I have been told this is not possible on an iClient system.  I have no knowledge of iFix and its HMI programing but this does not seam reasonable.  Can anyone provide any input on this? We mainly would like to use the second monitor to display security and video information for the plant that we already have a windows based application built.   I really do not want to have an additional system just , for this considering we already have a primary and secondary iClient workstations setup. Thanks in advance for any assistance and information.

  21. Hi, I have AB Micro820 PLC (2080-LC20-20QBB) which, acc. to the specs, can be both Ethernet/IP master and slave. I need it to be a master(scanner) and communicate with a KEYENCE DL-EP1 module, which is Ethernet/IP slave(adapter), but don't see any way to make that happen. How do you declare/configure Ethernet/IP slaves in Connected Components Workbench and how do you add slaves to your CCW project? I have an EDS file for the slave, but what to do with it? I imported it (have no idea where) with the EDS hardware installation tool which reported all was OK, but do not see the slave anywhere in the CCW. I only see in the Device Toolbox > Discover, but the only available option there is to remove it :) Thanks for any suggestions. Peter
  22. Hello. I'm having another issue regarding NT2S Display. Again I'm trying to convert my old project I made in NT2-ST software to NTXS software. I'm now having problems with: how to automatic go to screen1, if user doesn’t press any key for let's say 2 minutes? In old SW I have constantly checking DM00000 (screen trigger register) in PLC. If screen reg didn't change for 2 minutes I have write 1 to DM00000 (screen trigger register). With new software you cannot write to screen register directly. Or am I wrong? Did anyone do this function using NTXS software? Best regards.

  23. PLC Integration by SCADA

    Jairus posted a topic in Siemens

    Hello Experts, Good day to you all. I just can’t figure how I will integrate five S7-300 PLC. CPU 315-2dp. (1.Blow moulding-> 2. filler-> 3. labeller-> 4. packer-> 5. Palletizer) I just want to get the speed of its machine, the output rate and the alarm, this is purely monitoring, archiving, no need to control anything here. I planning about SCADA system. I’m thinking if I could do the same way in my previous project, which I’ve done in profibus master/slave for two s7-300. But this time the five PLC’s already set the profibus as master to the danfoss drive, sew drives, ET200s and many more profibus slave. I plan to buy 1 PLC as master and I will set all as slave, but how since all the five existing PLC, its profibus already configured as master. Thank you very much. All your inputs is really appreciated.
