  3. Hello.  I'm trying to help someone with a sawmill find a way to input from a sensor to connect it to the PC.  Not sure where even to look to ask for help. but here's what I understand:   The sensor is a SIKO MSA-213C Magnetic Sensor, using EtherCAT.  This interfaces with     SSI, BiSS C, IO Link They just need to connect it to the PC to work with it.   It could just connect to a USB port somehow, or the etherCAT option.   I found this:  MB3U    BiSS (SSI)-to-PC Adapter (USB)  link to .de site   any suggestions or pointers would be very helpful!    These folks don't use the internet, so I help them.

  6. Hi new to the forum, and first post, however, I have found an abundance of great information here, so I was hoping someone might able to help me with an issue.   PLC is BRX BX-DME1-10ED13-D I am trying to read an analog output from a sensor that is capable of essentially outputting a mA signal proportional to where a printed line, or contrasting edge is at in its field of view. It is used for web guiding applications to make sure the web is tracking straight, so you can identify if the line or edge is moving to one direction or the other, and correct the web with an articulating web guide. I have attached the diagram for the sensor, but I cannot for the life of me figure out 2 things 1) The power supply to the sensor is listed as follows Supply current - From fife control +/- 12vdc 50ma (+)12vdc  AND   - 40ma (- )12vdc how do you provide both (+) and( -) 12VDC for the supply power to a sensor- 2 power supplies with the the opposite polarities grounded on each?   2) The outputs are listed as "Sum" and "Differential" so apparently there are two outputs, i dont know if anyone has come across these terms relative to sensors before, but I am trying to sort these out. According to the OEM  Sensor Output Range   -20 mA to +20 mA for line guiding     -20 mA to +10 mA for edge Guiding   I have attached the pin out diagram as well as the sensor spec sheet, but I am curious to see if anyone might have insight as to how I would get an analog input reading from this configuration? Thank you in advance for any help!     224615.pdf SE-26B Product Sheet.pdf
  7. FX3U Stop Reading Channel Data

    Hello Everyone,  Need help with reading channel data of FX2N-4AD with FX3U Cpu. I have added all the logic and it works also. Problem is that, FROM function stop reading/fetching data from FX2N-4AD after some time i.e couple of hours and value just hang. Like 502 or something, untill you reset the whole PLC. What could be the problem. For the further info, -I have connected the FX2N-4AD on the right of fX3U-64M. -There are two extension blocks FX2N-16EX and FX2N-16EYR also added to the right of FX3U-64M -Order of mounting....FX3U-64M > FX2N-16EX > FX2N-16EYR > FX2N-4AD > FX2N-4AD   I have tried using the 2nd special module connected at the end, but It showed similar problem after few hours of running. THis shows that both Special blocks fx2n-4ad are okay. There is something wrong with PLC maybe? Please help
  8. FX3U Analog Programming

    Hi,  Anyone can help how to program a analog coming from a level transmitter? I have 8 analog inputs (2 unit of FX3U-4AD) to be read out into the plc program. how can this be possible. I'm new to mitsubishi analog. it is different from my experience(using siemens before).   Hope someone can help.   Thanks!!!   Marky
  9. Hello I would like to first let everyone know I am new to the world of troubleshooting or programming plc's . What we have is a SLC500 system that is connected to a Panelview 1000 HMI via the DH+ network. The issue we have is the panelview displays a gate that is suppose to be closed at as gate fault. When i connect to the plc the ladder rung shows that the gate is closed. To show various positions of the gate the programmer used N13:70 as gate opened and N13:71 as gate faulted and N13:72 as gate closed. When i checked the logic it showed the bit N13:72 as engaged or true if you will. This logic is in the ladder rung that is labeled PV Status which i take is the status the HMI reads so my question is why does it show GF when it should be reading GC. Ive searched all through the logic and it doesnt appear to be wrong here is the logic the best I can simulate it  ladder 6 rung  53  instruction is  XIC O:13.0/11 and OTE N13:76/0 (Gate Open ) and the branch is XIC I:5.0/11and OTE N13:76/1 (Gate Fault) next branch is XIC N13:3/11 and OTE N13:76/2 (Gate Closed which this section is green or highlighted or true which ever you like) when i looked at the input XIC N13:3/11 this is what I found is that this XIC is on ladder four rung10 and has the following XIC T4:154/DN and branchoff that is XIC I:5.0/11(gate opened)XIC I:6.0/11(gate closed) which these two inputs are false or not lighted the output is OTL N13:3/11 and it is true which makes the previous rung true showing the gate closed. So why is the panelview showing the wrong position. I even went as far as resetting the HMI and the PLC so if anyone has a helpful hint I would greatly appreciate it.
  10. Modbus Addressing in Weintek HMI

    Modbus addressing in Weintek HMI to poll data from Temperature sensor through RS485. In my system i have connected Temperature sensor to I/O Scanner has output in terms of RS-485 which directly connected to COM3 Port pin. No. 6 (as Negative) & 9 (as Positive) of HMI (Model No: MT8071iE) and HMI connected to PC via ETHERNET. I want to read temp on HMI screen via MODBUS protocol. So, can you please provide me instruction about addressing of MODBUS register in Easy-Builder Software so can read data of corresponding register. Because when i do compile i got an error like " Device no Response". I hope i will get reply from your side as Fast as possible to overcome this problem. Thank you.
  11. Hi All, I am doing an application that use servo motor to feed plastic film to a target length (set by operator), and it need to stop immediately if marker sensor is ON. This application is control by Omron CP1E PLC. It will feed plastic film in 500-1000mm/s depends on the target length set by operator. It is require to stop immediately if the servo feed length more than 90% of the target length and the marker sensor is ON. However, is there any possibility for the servo to stop immediately once the condition is meet? As I am using PLS2(887) to feed with target length, and INI(880) to stop immediately, however, it cannot get the desired result as servo not able to stop immediately after marker sensor is ON, I am not sure is because of the PLC scan time, or servo need time to deceleration (deceleration rate assigned to #FFFF). Appreciate anyone able to assist on this. Thank you.
  12. Hi everybody, I have a GT2310 communicating with the Mitsubishi F800 VFD. I am using the Freqrol 800 communication driver, connected to the RS-485 terminals of the GOT and on the F800. The comm settings are the same on both devices. I also tried to use the “auto negotiation” setup. I have communication between the two devices. I can read and write to F800 registers.   Anyways, The GT designer diagnostics is complaining about a communication error in the system alarms. The error can be reset but it will appear again.   This also happened when I created a new, empty project where just the communication was setup as described above.   Did anyone experienced the problem and how to troubleshoot / solve this?   Best regards

  14. iFIX restore problem

    Hi, I have .fbk backup file of iFix aplication (i mean).. When I try to restore it by "Backup&Restore Wizard" in part where I "Browse" the way to Backup file and click on "Next" is problem. Pop-up window show -> "Bad file format. The archive file may be an old version or a wrong version in header signature or is not a Proficy iFIX full backup file (.fbk)" ....  My question is = Is possible to find what of version is my backup file ??? when i suppose this error mean i have installed wrong version of iFIX sofware (my version is iFIX 5.5).. Or is no problem of my iFIX version ?  Thanks
  15. Hi Everyone..I'm having hard time to read Analog Sensor. I've try to read the manuals about expansion module, but still having hard time to understand it. My PLC is CP1E-N30DR-A connect with Expansion CP1W-MAD44 and I'm trying to connect with pressure sensor Omron E8F2-B10C that in a certain pressure will trigger to open a Digital Valve. is there something wrong with my setting for range? I do the setting in 4-20mA (0-5V) I attached my Program and Picture while running, the program is only for reading the pressure sensor. the result is  -600 to +600, is there a way to earn the actual result? I've tried Scaling and APR, But didn't understand, is there a guide/tutorial for it as well?   Cheers.. Albert TEST.cxp TEST.cxp
  16. CP1L connected with scanner symbol DS-4308 reading 2D data matrix,  with RS-232 on board CP1W-CIF01 Hi all, need some help because I can't read the information. Let me explain, I have a PLC, " CP1L-L14DR-D " with a RS-232 option borad " CP1W-CIF01 " , a scanner Symbol DS-4308, and I'm trying to read a data matrix 2d barcode (I don't know if that matters). so I build a cable with the next configuration, (one side male and the other female) PORT CONFIG PIN OUT SCANNER CABLE RJ-50 TO RS-232 PINOUT Maybe I'm missing a connection? a bridge? power supply ? ground?   in the program, I only have this to check the communication,       When my reception flag complete (A392.06), my instruction RXD is going to execcute, reading in D1500 the data. if is any error in communication (A392.04) or overflow (A392.07), my port is going to restart (A526.00) (ignore w0.03) with the followign config: (9600, 7,2,E, RS-232C, End code: Received Bytes 3       and I'm reading only, data on D1500 and D1501, and the data makes no sense.   with the configuration of End Code: CR, LF,          can't make it work, I read nothing. and if I change the END CODE: Received bytes to 4,      don't work. and my flag A392.04 go to ON.   PLC HAS 4 PIN SWITCH, ALL ARE OFF The configuration on the scanner is setting to default and then config to RS-232 Standard.   So, what I'm missing?  bad connections? plc don't support? scanner config? program?      
  17. Hi guys....first post here. It's been about 6 years since I worked heavily with PLC's and automation, but I'm getting back into it. I was hoping you might be able to help me with an issue I've noticed at work.  Problem:  The sensor we use just reads if there's something there, or not. A make or break if you will. When boxes are pushed together and there is no gap between them it thinks there's a jam (after 6 seconds) even when the boxes are moving past (as they should).  A jam stops the conveyor belt requiring someone to physically move the boxes to clear the sensor and restart the equipment.   I'm trying to find a sensor that will see the distance changes from box to box (mounted on the side of the conveyor). Only when there is a true jam and the distance isn't changing will it send a jam signal.  I've tried researching sensors and have been overwhelmed by the endless possibilities and combinations (not all of which I understand).  We are currently using an Allen-Bradley 42EF-P2RJB-A2H It would be ideal to have a similar style plug, but it isn't a deal breaker.  Here's an idea of what I'm dealing with. (The actual conveyor the jams are occurring on is a decline belt, not a roller accumulator.) There are varying box sixes, but they are all packed together. Creating a gap between boxes or using metering belt is not an option here. Thank you for any help/guidance you can offer! -Steve
  18. Hi,  I'm new to TwinCAT 2 and i'm upgrading a long time design (hence the TwinCAT 2 reference), to read a more sensitive torque signal.  I'm using a Beckhoff CX1030 as my PLC Controller.  I needed to add 'homing' to my motor sequence and confirmed with Maxon, im using the function blocks correctly and in the correct sequence to establish my 'absolute zero'/'home' position.  The motor has an output to write to:  ControlWord, which tells the motor that the position it is sitting in is '0.'  My program compiles, it runs, it writes each function block, but it's not seeming to get back to the test run opMode, even though i tell it to and the function block performs the 'Write' function.  it's stuck at zero and not reading an analog input signal from my torque sensor.  so im getting an artificial torque reading through every test.   i think this is related to my tare motion.  I start the program, home the motor, get into profile velocity mode, tare my sensor, enter profile position mode, go back to position 0, then back to profile velocity mode, run a test, sample data, go back to 'home' or '0.'  I wonder 1st, is my variable not linked properly through the system manager?  2nd, i set a boolean variable to set the 4th bit to 1 in my control word write (setting the 4th bit high will set my current position to absolute zero), but did i not connect the program to the main sequence properly?  looking to read a valid signal again and see that my motor moves back to 'home' each time.  Do i not need to home the motor after the tare, since the tare nulls out the torque value after the tare? after this i need to program my sample period, instead of it being fixed, as it is currently written and then use my home position as my trigger to start sampling.... Beckhoff applications department is overloaded, currently and can't help and this is all beyond the knowledge of the general support line.  I've gotten fairly far, on my own, but of course, the project is under a time crunch.   Does anyone know twincat well enough to help guide me?
  19. Hello i'm new in all things about plc, i do a project for school and i use a festo fc 34 plc.

Have a nice day.
  20. S7 300 Profibus fault

    Dear All, We are in need of your expert opinion. One of the nodes of our Crane's Cabin gives a station failure problem, due to which whole Crane shuts down. we have done everything from replacing Dp connectors to changing Profi cables, swapping modules with other stations, changing Power supplies but the problem remains the same. Following are the system details, 1. CPU S7 319 F3 fail safe 2. IM 153 interface module 3. OLM module for signal conversion fibre to profibus from main CPU.   We have several nodes after OLM but fault was persistent with 3 nodes. After comprehensive working, it came down to just one but still not diagnosed. I will also upload the diagnostic buffer if needed.

  23. So, hello all. I'm new in Omron PLC. Using: CP1L-EM controll + CP1W-TS102 (x3) Problem: I have PT-100 sensor outside, so, cause i live in Russia, we have now -3 ... -5 under 0 =)  What i've done: I read the manual W462. Made some ladder (attached).  When i have temperature outside - i have value &2 or close to it, what means 0,2 degrees (i use Celsius) But when the temperature go down, i have &65535 and my PID go crazy.  So, i understand that it's 2 complement's but... HOW I CAN GET THE VALUE IN REAL??? (+2,0 or -5,3 and etc....)  Okay, go across the manual, what we see? (pic2)  We see the instruction for CP1L with PT-100 in range of -200...650. Ok, perfect, what i need... but... I HAVE NO SBB(051) INSTRUCTION IN MY CP1L!  So, guys, i need ur help with that. I need negaitve temperature in real with sign for using it in scaling, pid and HMI via NB-series panel.    Sincerely, p001p
