  3. 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.
  4. 1734 AENTR series B

    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. 
  5. I have set up a timer in exostructure expert basic and am trying to get the contdown value from the preset of 20 to show in vijeo designer but it tells me the %tm0.v is read only and cant find the variable in Vijeo designer to show it. Does anyone know how to do this?  
  6. Hitachi H-700 Series

      Welcome, How to program this PLC?  
  7. Can You explain me how can I reset a Timer so that after completion of the cycle, it automatically starts again from 0 sec in CX Programmer? I am working on a program for a Oxygen PSA Plant. In which the valves of 2 cylindrical tanks switches at a specified interval and the cycle keeps on repeating. Thank You.
  8. Hi all, I am trying to communicate KEPServerEX with FX3GE vis UDP protocol. I have tried but unable to get data on Kepserver. While configuring communication properties in PLC we have configured PLC IP, PLC Port, Destination IP, but unable to find correct Destination Port. Although we tried various port nos like 49320, 57412, 57512, 56233, 1025, 32402, 57212, 57012, 57612, 57812 but there was bad quality data using UDP For same PLC using TCP/IP we were able to read all tags properly. This change in communication protocol is required as there are some PLCs whose communication port drops after few days of connection establishment (no error logged; can be re established with just restart). Someone from Mitsubishi said to try communication via UDP as it continuously fetch data regardless of kind of response received. If anybody has tried or have any solution, please do share.   Thanks
  9. 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
  10. FX3GE Communication issue

    Hi all, There's an issue I am facing for multiple FX3GE PLCs in a plant. Communication breaks between a PLC and OPC server. PLCs after few days (4-10) does not respond over ethernet. No ping response is received over network as well as when checked one to one direct connection. If I restart the PLC the connection is resumed and again after some days it goes down. Error LED on ethernet port does not glow red (no indication for error). If anybody has faced similar issue and has resolved, please share.
  11. 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    
  12. 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.  
  13. Hello Everyone, I am writing one logic and need some help regarding that logic.   CURRENT LOGIC -  -There are two timers TON_1 and TON_2. -TON_1 timer will start as soon as PLC turns on. -After the done bit of TON_1 timer, the TON_2 timer goes on. -After the done bit of TON_2 timer, again the TON_1 timer will start. -This logic cycle will run continuously, both timers will run turn by turn. Code (Codesys/Schneider Eco Structure Machine Expert)- PROGRAM POU_1 VAR      TON_1: TON;     TON_2: TON; END_VAR TON_1(IN:=(NOT(TON_2.Q)) , PT:= T#100S); TON_2(IN:=(TON_1.Q) AND (NOT(TON_2.Q)) , PT:= T#20S);   Actual Requirement -  -There is a BOOL tag. -If the BOOL tag gets high during the TON_1 running, the logic should move to the TON_2 immediately. -If the BOOL tag does not get high during the TON_1 running, the logic should move to the TON_2 after completion of TON_1. -after the completion of TON_2, again restart TON_1. -Logic Runs continuously in a cyclic mode.   Give me your valuable idea to fulfill the logic requirement.
  14. Hi All,  I am trying to limit the number of character for user to key in data edit . However, I put numbers inside it shows me invalid number of character. Anyone know how to solve it ? Note; My variable is in String Type   
  15. 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

  17. GX Works 3 Timer (TON)

    Hello, please help me deal with this problem. Mitsubishi GX Works 3. I can not understand why the TON function block does not work correctly. I need to set the timer in minutes, but if I set 55 minutes, the timer doesn't start and an error appears. How do I make a timer to avoid this? Going through the values, I found out that this happens with the numbers 55-110, although at times large numbers work adequately. t_0 - DINTflushing - TONapplyNewTime - Bit
  18. 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.

  22. 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!

  24. Hi,     I'm trying to communicate Omron CP1E unit with PC via serial port using hostlink protocol.  I need to read the Timer/Counter SV value and write the timer/counter SV values to the PLC.  I'm able to use other C mode commands (like RC (timer/counter PV read), WC (timer/counter PV write) etc.) but when I give the command for Timer/Counter SV Read 1 which is R#, I get the response as IC (Undefined Command).   How do I write or read the timer SV Values?  Example command and response : @00R#TIMH001028*  (TIMH is the high speed timer, 0010 is the timer number and 28 is the FCS) Response: @00IC4A* Is is that CP1E doesn't support these commands? If so what is the equivalent command that I should send inorder to perform this? Please help.
