  1. connection to omron CJ1M PLC

    I have an omron PLC (CJ1M type) at home which I would like to connect to, however, lately, I can't anymore.  I'm trying on two different PC's a newer and an older one, both running on windows 10. 1 is just mentioning a DLL error and I can't even start cx-programmer, the other one seems to work, however, when I try to go online it always fails I'm using a usb to serial device and after some searching on the net, I thought the issue was with the prolific driver.  I tried all kind of fixes, but nothing seemed to work.  I have now purchased another device, the XS8801 from usconverters and installed the latest driver.  I have checked if cx programmer is set to work with the correct port and this is the case. My knowledge is very limited but I would really want to connect to that PLC again, so hoping someone out here is able to help me. Thanks a lot    
  2. FBs-CBE distortion

    Hi every one After sending some command to plc using fatek FBs CBE module , router internet connection goes off and internet LED turn red. i mean it works fine for a minute.. then internet connection of router will be off...  why this happens?
  3. Hi All! Can anyone help me regarding the following logic: 1. I have four Silos and one filling station. 2. The filling of silos starts on the bases of silo demad (i.e demand is a digital signal that comes when silo is empty) 3. I have to fill all silos according to their demand 4. Whose demand is first that is filled first 5. for e.g if all four silos are empty they all generate a demand signal. 6. If Filling of silo 1 is done and filling is in progress at silo 2 after that filling will start  in silo 3 then silo 4 as they are empty 7. In the mean time  if silo 1 empy again and filling is in progress at silo 2. The system must fill silo 3 and 4 first then go to silo 1  8. It means which demands first that is filled first (first come first serve)   
  4. Check serial connection to Omron PLC

    Hello, I am building an application in CitectSCADA and I want to communicate with an Omron Sysmac CS1G. The connection between the plc and the Citect computer is through an ethernet to serial adapter (the computer doesn't have com ports on board). I'm having some difficulty establishing the communication and I want to make sure that I can actually reach the plc. Is there a way to check that the computer can reach the plc over the serial connection without using CX programmer? Maybe using Hyper Terminal, Putty or something similar. Thank you, Liron
  5. QD75M4 AND MR-J2S-40B

    Hello i have problem about connection between QD75M4 AND MR-J2S-40B  now MR-j2S is display "Ab" every time i can't solve this problem 
  6. HI All,  I have an issue with my SCU32 communication.  Back ground Two SCU32s  (top and bottom side) connected via a 1100M datacable  using port1 ( 9600bps,  8-2-E, start code FF, end code FE, Tx save to d1000-d1200 , Rx save to d2000-d2200). PORT2 of bottom SCU32 is connected to a compass( 2 wire, 8-1-N, 19200 bps, serial gateway MODBUS ). Refer to photo Issue  Without compass, the receiving data at top is very stable and is didn't see any fluctuation. But if is compass is connected at bottom side port2, there is a fluctuation at the top side RX data(specifically d2000-d2005 ) .  I checked the data a bottom side TX (d1000-d1200) and it is stable. Only after sending the data and Receiving at Top side, then only the starting words fluctuate. I am not sure sure what is wrong, I am using logical ports for the DTXDU/DRXDU and compass.   Appreciate all your feedback and suggestions.  
  7. I need a Red Lion HMI to communicate with an IO module (8) IO's ... I don't really need a PLC.  Because the control of a certain LinMot drive for a linear motor can be activated by IO's.  This LinMot drive can store up to 100 curves... which can simply be called into operation by a single binary number between 0 & 255,  defined by eight IO's ..  you input the number on the HMI, the HMI converts to binary and set the (8) IO's in the module which sends the binary number to the LinMot drive..   Yes, there are some other IO's for starting and stopping ... and it may be unrealistic for me to not use a PLC.   I'm trying to get the cost way down...    If a "stand-alone" IO module does not exist... then is there a simple, low budget PLC out there, with 8 or 16 IO's available..?    Thanks much, Michael
  8. IC200ALG264 Analog Input module

    Hello all, Thanks for the forum which has provided me with a lot of help overtime. I'm posting my first thread since I can't seem to find an answer to my issue. I'll quickly explain the situation: I'll be installing a RTD sensor to a GE Fanuc IC200ALG264 analog input module using a 4-20mA converter. Everything is fine except I can't seem to understand the polarities of the Fanuc inputs. I'll explain better: the module has an IC200CHS022 for the terminals, 15 terminals total, and the manual is reporting a "number" and a "connection" for each terminal. Now, the "number" seems to correspond to the visible pin of the terminal. But the positive and negative symbols are represented on the "connection", which I can't seem to wrap my head around what it means. Attached are abstracts from the manual and a photo of the terminals. Please tell me where to connect positive and negative outputs of the 4-20mA converter. Thank you.

  9. Hi! I would like to ask how could I send data from PC to CJ1M PLC, by SCU-41 module and RS232 cable, in order to activate an actuator (LED)? In my environment, I have a sensor that sends data from PLC to PC (I'm checking data, "HelloWrld" with Putty), with this configuration: And I have another section where I want to read the data from the PC in ordr to activate a LED I would like when I send for example a letter 'a' trough Putty, the LED activates. How could I do that? Thank you very much!
  10. Hi All need to convert a Decimal Value into Ascii code to send out on serial 485. eg. Weight comes in as Int 12345 i need to send it out in Ascii as 23 32 20 31 32 33 34 35. I have created an array 0 of 8 (Word) DB. Is there an easy way split the int into Digits convet in into HEX and slot the value into the various array positions? Array 0 of 8 = 23 means # Array 1 of 8 = 32 means 2 (Station ID) Array 2 of 8 = 20 means Space Array 3 of 8 = 31 means 1 Array 4 of 8  = 32 means 2 Array 5 of 8 = 33 means 3 Array 6 of 8 = 34 means 4 Array 7 of 8 = 35 means 5 Array 8 of 8 = D means CR    this sends the value of 12345 to Display ID 2 . need help to convert the decimal number in ascii. the decimal number will be max of 5 digits and less than 32000   any help will be greatly appreciated.

  12. Hey everyone, I have a CJ1M PLC with a CJ1W-SCU21-V1 serial card. It is unit 6 and I am using port 1. I have bit 1659.06 ((1500 + 25 * Unit #) +9, bit 6) as "characters in buffer" but it never comes on (data is being received through the port successfully). It is on No-Protocol mode. Does anyone have any ideas as to how I can detect data in the buffer?
  13. Serial comm with FX1N PLC

    I need to communicate with a Mitsubishi PLC using Matlab. To do that, I open a serial communication with the appropiate parameters (7,e,1,9600), and write an ASCII message based on the manual I have (attached). I have tried examples as the one in the attached image. The response starts with a 6, that is, the ASCII number for ACK, so something must be working. But the rest of the response is junk (149, 149, 149...), although its length depends on the input length (if I add terminator, the response is longer, and so on). I am completely stuck. Some information that might be helpful: I am using a Serial to USB converter that I have used successfully with other PLC (which used Modbus, so everything was easier) There's a VB application (of which I don't have the code) that is able to connect to the PLC (I need to connect directly without using this intermediate app). I have decompiled it trying to get some info, but was just able to confirm the 7,e,1,9600 parameters, since the rest of the code is too mangled to analyze The attached manual was sent to me by the guy who designed the PLC and its ladder code, so I guess it is the correct one I have tried the echo mode (TT) to no avail, response is always the same I have some doubts regarding the reading of a value (see attached image). Why is there a second message from the PC? Shouldn't I just need to read the response? GX Developer tells me that the address D8120 (which is supposed to define the comm format and protocol) contains a 0, which seems weird. Any help or hint would be greatly appreciated. Thanks jy992d69901e.pdf
  14. Hi all! We have a problem with a Mitsubishi system. After switch off the machine in home position and back on, it resets the servo encoder value to 0.  I checked the servo parameters, and the Absolute encoder is enabled, the ext. battery is ok and no zero reseting in the program ( I think...). Is there a parameter I should check or some setting in the intelligent module? The system consists Q01CPU, QD77MS2 im., J4 200B amp with 6v battery, and HG-SR152 motor.
  15. PID Loop Review

    Hi all, I am trying to set up a PID loop for a project I'm working on, and I was hoping someone could take a look at it for me. Most of what is written comes from the Q, L programming manual, but I've changed a few things so that the program can write changes to the SV as needed. The processor is a Q03UDE and the Analog Module is a Q64AD2DA, using only channels 1 and 5. Thanks for looking! PID Project.gxw
  16. Sorry for my bad english speaking. I want to change the baud rate to 19200,38400,.... for send it via Programmer-Serial-Port. The software GX-Developer can do it!. When the PLC is switched on, we generate a value in the data register D8116 and D8117. GX Developer reads the PLC type and data registers D8116 and D8117 at startup and generates a value. This value is written in D8118 and D8119. The big question is: how is D8118 and D8119 generated ??

  22. Hello guys, I am very new at this. I am trying to make a Schneider PLC (TM251MESE) to send some serial commands (485)  to a integrated stepper motor from Automation Direct (STR-MTRD-17030RE, but I am lost. The driver has been program to receive the SCL commands. But not quite sure how to send those from the plc. Im using SoMachine V 4.2 Have any of you done anything similar? Any example will be greatly appreciated.  Thanks 
  23. I have been able to Jog the opposite direction from a Hardware OT with my 1S servos (using Sysmac Studio).  I reset the OT Fault and Job the opposite direction. What I am having trouble with now is, I have set Software Limits and I cannot Jog off like I can with the Hardware OT.  I have been told I should be able to do that, but it still does not work.  The fault returns immediately when I press the appropriate HMI Job button....which is the same HMI buttons and Logic used when I have the Hardware OT. Has anyone ran into this before?  It may be a setting I have not done right maybe?? Thanks,
  24. Still learning Sysmac Studio......how do I gain access to System Variables like 'PageIndex" so my PLC can be notified what Page the HMI is on?  Also, how can I execute an 'Acknowledge All' from the PLC so I can reset the 'Alarm Viewer Popup' from my PLC? Thanks,
  25. Hello Everyone, I am new at this forum, seeking help from you guys and gals. Scenario: I have a Controllogix 1756-L71 5570 controller installed with 1756-TIME module. The function of time module is to take time from GPS clock module in NTP format and send it to controller in PTP format. All the status LED's on Time module are OK. Also sync LED is Green. Still the time of controller is not synchronized with GPS clock there is a difference of 45 mins. Fellows please help. I'll be helpful.
