  1. Logicmaster 6 Keyboard Translator Chart

    Hi, I was wondering if anybody could post a photo of the Logicmaster 6 IBM PC keyboard translator chart? This is a 'tear out' page from an appendix in the Logicmaster 6 programming manual. The 'Logicmaster 6 Programming and Documentation Software User Guide' Appendix C refers to this chart as follows: "This appendix contains a keyboard translator chart to use with the IBM-PC, PC-XT, PC-AT, or IBM-compatible personal computer. The chart has been printed in triplicate to provide you with extra copies. The sheet has also been formatted so that you can remove each copy of the chart from the manual for easier reference." All the hard copy manuals I can find have this keyboard chart removed and online pdf copies do not show this page. your help would be appreciated.

  6. I'm editing a dual language project for an NA5 HMI. It's working fine except for the message at startup. To modify the project I've had to update the firmware on the HMI. I'm using Sysmac Studio 1.15. Startup language seems to be set correctly. Any ideas?

  9. Q-Series - Operation Error 4100

    Hi guys. I found error on PLC and from PLC diagnostic I found this Operation Error 4100 as per attach picture. FYI, there is no SD card mount onto this PLC. I wonder what is ATA card. This error wont affect the operation. Any advise on what to check?   This ladder is pop up when I clicked, error jump.   Thanks.
  10. Hi, So I have a problem, that BootP DHCP server doesn't find my 1734 AENTR series B and so I can't assign IP address to it. Been trying many things. Any advice? I'm new to AB and I guess it may be a really easy thing but so far I didn't find a solution. 
  11. HydMech control issues

    I have a HydMech H14A Automatic bandsaw that I am currently experiencing an odd issue with. When in Auto the saw operates fine, but when in manual the rear vise open function is not working. I have a signal from HMI to the input at the PLC, but no signal coming from the corresponding output. The status light for the output (Y012) never lights up when in manual, but, again, the saw functions flawlessly in Auto. Have changed HMI, PLC, ribbon cables for input/outputs and comm cable. When viewing program to asses issue, i have to unplug the comm cable in order to plug in my computer, meaning that even though I can see logic, I cannot see it during operation. 2 things. 1- on the off chance that someone has experienced  this same problem, what did you find? 2- is there a way to view program while it is actively running code? Hardware= Mitsubishi Melsec FX3UC-32MT/DSS, Software= MELSOFT series GX Works2

  13. PLC Reset?

    Hi guys, I always wondering, what is reset when reset button is click? Does the setting from address D from HMI will be lost? Does internal memory of PLC is reset? Anything thats not reset? Or just reset sequence? Thanks.
  14. I am new to automation systems and devices and I just want to know how to connect two HMI's (each one would control different things) to one PLC using Sysmac Studio and NB-Designer via Ethernet. The model of the PLC is NX1029020 and the HMI's are one NB10W-TW01B and an NB7W-TW01B. I searched for info about this topic online but I couldn't find anything that worked for me, I saw an article from OMRON where they connect two NB's to the CP series, but in my case, NB designer doesn't allow me to insert more than one HMI in the same project, I also found something similar on a youtube video that gave me an idea about how to connect multiple HMIs exporting the pks file and importing it to another HMI project but I still can´t figure out how to add both to my PLC. I would thank you a lot if you could help me with this because I know it's not a rare implementation, just I haven´t found the right way to do it. I also leave the links to the Omron article and the youtube video I found. https://www.myomron.com/index.php?action=kb&article=1554 https://www.youtube.com/watch?v=rXx5lut7G9I
  15. Q and iQ-R series

      Hello,  I want to know, if it is worthwhile to transfer from Q series to iQ-R? Currently our equipment is using Q series, which ss a vacuum coating equipment with about 10 power instruments, 20 gas controllers, and pumps and so on. As for the analog and X, Y points, Q is quite capable.   I can not see any advantage to switch to iQ-R, but some people want to. So I want to know,       1. will Q be outdated in the near future?       2. will use iQ-R cost much more than Q? including peripheral units.       3. has iQ-R really been widely adopted?       4. thoug iQ-R may be powerful, I think use multiple middle size CPU's can be more advantageous,              is this right? Many thanks in advance. Ting    
  16. I have a huge confusion regarding the retentive timers on FX3GE. According to the programming manual for FX3G(image attached), all retentive timers use the EEPROM. This is very confusing to me because the retentive timers are modifying the measured time constantly in an EEPROM register and EEPROM type of memory is known to be write limited. After a couple of million write cycles the EEPROM registers burnout. I've experienced this myself by constantly using the T250 and after a while it became unusable. The timer stopped counting time after some time. This leads to my decision that retentive timers on FX3GE PLCs are something that should бе used only on rare occasions so as to avoid EEPROM memory burnout. If this is true than the real question comes in: What is an alternative for using retentive timers on FX3GE when you want to measure time between two events. The instruction TTMR for teaching timer is appropriate however this instruction does not exist on FX3G series.  
  17. I am trying to online edit a program in a MELSEC QCPU, using GX Works2, but I keep getting this error "A file which does not exist in the PLC was specified" <ES:010a4022> Few weeks ago I had just online edited the same program in the same PLC with the same steps with no problem. There had been no changes to the PLC after that. Just all a sudden when I try to edit yesterday I get this error. Not an expert in Mitsubishi, just started learning the basics. Connection to PLC is by USB cable. Steps I followed to connect to PLC:    -Online > Read from PLC    -Select PLC Series: QCPU (Q mode)    -Select PLC side I/F Serial Setting: Serial USB    -Select all target program to Read, then Execute I am editing the file that I had just read from PLC Steps I followed to online edit:    -Online > Monitor > Monitor (Write mode)    -Execute the function below when mode is changed: Checked all    -Edit the program (basically just deleted one -||- contact and drew back the line)    -Compile > Online Program Change Then Bam! error get! "A file which does not exist in the PLC was specified" <ES:010a4022> I had tried Verify with PLC, but all results match. Is there something I am missing? Help much appreciated!
  18. Backup Legacy PLC

    I am looking into how to connect/backup the existing programming on some legacy PLC's. I have been trying to find the information on this site, which is awesome!  But I feel I am getting lost in all the different software/PLC's types.  As I understand it, we have a Melsec-A or A2AScpu.  Now there is what appears to be a pin cable when you open the swivel door on the PLC that would allow you to connect it to a PC. Where I am getting lost is "do I need a specific cable for this, I know some pin cables will have the wiring line up differently per the pins"  and or "what software would work best to allow me to take a current backup of the existing programming on the PLC." Please understand I am new to PLC's.  But I am willing to learn, right now I am thinking about using some older PLC's we have that are not in use to start with so I can learn but I just feel a little overwhelmed with all the differences in both PLC versions and the software you can use.  I also think if I can lock in the backup/restore process i will always be in a position to revert back should (more than likely) I make any mistakes. Any help with pointing me a good place to start for the specific PLC I am referring to would be really appreciated.

  20. Hello, everyone I have to query a SICK distance sensor from an L26CPU via the onboard Ethernet interface. I have created a simple protocol which I start with the function block SP_ECPRTCL. Unfortunately it takes at least 25ms until the next telegram is started. The sensor responds within approx. 1.5ms. Does anyone know whether that works faster or is that a limitation when using the predefined protocols? Sensor manual:  OD5000, 8021391 (sick.com)  (Chapter 7.4) I am grateful for all the hints. Thanks and regards Dave SICK_Protocol.tpc Messaufbau_vTest.gxw
  21. Hello Mrplc's members I have a Korean version " goldsec Moj2" of Mitsubishi plc A0j2 I need to know the right software for it And how to get it I tried GX Developer but it didn't work because it have only A0J2h type And I tried melsec medoc (version 1.64) but it didn't have A series CPUs
  22. Hi, I have the following configuration where 4 PLC panels, with each having a Q12PH CPU and QJ71E71-100 module. All these QJ71E71-100 are connected to a HUB using straight cable. From the HUB one connection is going to an I-Fix SCADA which is already communicating with all 4 PLCs using MC protocol. I want to send data from 3 of this PLCs to the 4th PLC in the same network using fixed buffer communication. Can anyone provide a sample program for the same. Send and Receive side. I am using GX Works 2 for programming. Your help is very much appreciated.

  24. Alarm Comments Not Showing on GOT

    Hello! Im trying to set up Alarms on my project using GT Desisgner 3. My GOT is a GS Series, and my PLC is a FX5U. I usually just do a multi state lamp with descriptions for what's happening on the machine, but this system is much more complicated, so id like to do an alarm screen. I found a few sample projects, as well as tried both the Simple and User alarm tools on my own. However once everything is set up, when an alarm is triggered, the comment for that alarm is missing... The alarm time of occurrence, as well as turning green when its resolved all works on the screen, but i cant figure out why my comment doesn't show up. When in my project, all the "previews" of my comments show up great and are all there, just not on the screen itself...   Any help would be greatly appreciated! Thanks!
  25. Hello All,   Semi-noob here with Mitsubishi PLCs. I'm starting a project in which we are upgrading an existing A Series PLC with the Q.  Is there a datasheet somewhere that lists compatible software within Mitsubishi's lineup? I had no luck in searching their site.   Also, (in the same project) the existing network uses DeviceNet. I have the Q series compatible card for that - but within what software does one configure the network?   Thank you.
