  1. Hi Everyone, I have a small project where I need to detect temperature and smoke using Allen Bradley Micro820 PLC and send email when the temp is above or below a set limit. And since I'm new to PLC world I'm not quite sure which sensors would work with my plc model. It would be really helpful if anyone could guide me through and suggest any sensors appropriate for temperature (surrounding temp not liquid temp) and smoke. 
  2. Hello, denizens of Mr.PLC. I'm trying to talk to an old TSX17-20, and have acquired the DOS files for PL7 22. However, when installing via floppy drive, I'm getting a fatal error saying that the User Interface is missing. FATAL ERROR: 251 Your Telemecanique system in incomplete. Ensure that User Interface is correctly installed.   I'm aware that PL722 (and PL7-1/2/3, etc.) require Telemecanique's DOS User Interface to run, but I can't for the life of me find installation files, and, as it is no longer supported by Schneider, no luck getting it from their site. Apparently, it used to be hosted there. Would any of you wonderful folk have the links or files to this user interface? Apparently, PL7 22 5.0/5.1 have never required/no longer require a license. It was a drag to find these files, so I'm posting the PL722 files (in two zips, representing the two floppies) so that there's an easy to find reference for them. PL722D1.ZIP PL722D2.ZIP
  3. I am using DVP-ES2 PLC with DVP04AD-E2. I connected the flowmeter to the analog input module (4-20mA). And I noticed something weird, when the flowmeter shows 4mA value (no water flow at all) the data in the PLC keeps coming like 20-30 (0-32000). And when I change to the other port of the analog input , it even reaches value like 100 although there is no water flow at all. Note: I have done proper scaling to Liter/second and do proper grounding. Do you know what is the cause of this?
  4. I have a Siemens HMI 6AV2 124-0MC01-0AX0 in my machine. I want to clone the display on the HMI to PC/Laptop. My question is: 1. What software that I need for this task? 2. What kind of interface that I need between the HMI and PC/Laptop (for example ethernet cable, etc)? 3. Do I need to communicate with PLC connected with HMI or can I just connect with the HMI? Thanks in advance for the answer.
  5. Has anyone used 2 Keyence PZ series or similar retroreflective sensors in parallel to detect on the closest distance of irregular shaped objects? It should work if my sensor-fu is correct, but in actual use, has anyone had experience with it, and are there any 'gotchas' to watch out for?
  6. Connection cable for Sinumerik810

    Hi, I am trying to connect my M2 pg with a Sunumerik 810 cnc.    does anyone have the part number or pin out of the 25 pin-25pin tty cable that’s needed for this.    thanks   
  7. 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.

  8. 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
  9. There have been many good discussions on the applicability of cloud-based solutions for manufacturing and process control systems. On one side, some people have concerns regarding security and control of the information, on the other side, there are identified benefits enabled by cloud systems. From VMS minicomputers to DOS and Windows, from ArcNet to Ethernet, it is inevitable the industrial automation systems shall adopt the technologies that are getting predominant in IT general use; the current environment that I am calling the “Cloud-iPad era” is no different; therefore the practical discussion is not if those new technologies will be applied in the industrial environment, but how. This paper is not intended to join the conceptual discussion about the cloud, but just to present a few simple practical examples, where cloud technologies are already enhancing industrial automation solutions and enabling new business opportunities.

  11. 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.
  12. 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.
  13. Does anyone have any experience with the recently released user web interface for the iQ-F and iQ-R series. Supported by GX Works3 version 1.047Z or later, the firmware Version 1.100 or later. We have the sample user web interface running in a FX5U, its working very smoothly. I am currently looking into how to edit the html page, does anyone have any tips or useful tools/resources that I could use to work things out.       iQ-F Customer News regarding FW Update 08-2018.pdf
  14. Communication

    good evening. Someone can give tips on how to configure and physical the application with the following items: Advanced Interface Converters (AIC +), PanelView800 2711R-T7T A and MicroLogix 1500 Programmable Controllers My doubts are about the configuration of the communication, and I have doubts about the physical environment and protocol to be used.  
  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. 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
  17. 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?
  18. My client is a pharmaceutical company and they want to interface their Blood Gas Analyzer (which is a RAPIDPoint 500) to a Controllogix PLC via EtherNet. I have attached a Spec that I found, which gives the initial information you would need to do this. It says that the BGA can transmit data in ASCII. However, it doesn't list what bits I need to send to the device in order for it to send the PLC the data. I've tried contacting Siemen's (who makes the BGA) and they were useless. I also tried searching the RA knowledgebase.  Does anyone have any insight on how to communicate with a device in this way? Thank you Tyler RP500_LIS_5_20_13_-_Rev_C_.pdf
  19. I first saw AS-i at a factory this week and am trying to figure out what Allen Bradley modules can interface it. I am not finding anything, does AS-I go under some different name?
  20. Hello! Does anyone have experience of using tooth gear pulse sensors. I am looking for this kind of sensor for the machine, we are building. My problem is that the sensor we are using is not suitable for North American markets (UL-standard is not aproved) and now I am searching sensor like this. I am not sure is inductive sensors good enough for measuring this, the one that we have been using is magnetic field pulse sensor.
  21. I'm looking for some general information about different types of vibration/temperature sensors. What type, brand, model number, etc. will best fit my application.  Scenario: I want to monitor the vibration and temperature of multiple motors and gearboxes for a large overhead conveyor system. If an oil leak occurs and temperature increases, I want to see a temp. alert via a HMI. If a something mechanical fails, I want to see a vibration alert via a HMI.  I've looked into sensors that stick to the outside housing of the motors or gearboxes via a magnet. My concern is justifying the temperature readings. How accurate would a sensor that reads an "ambient" temperature be (compared to a thermocouple on the motor coil itself or some sort of probe)? Also, would the location of the magnet  on the motor or gearbox drastically affect the temp. or vib. readings? Has anyone had success with a similar setup? If so, what devices did you utilize? Are these systems truly beneficial?  I'm currently considering Banner's wireless products...
  22. Hi, Recently, we replaced our old digital temperature transmitter with a Baumer Flextop 2201 digital temp transmitter. The application of the digital temp transmitter is for a hydraulic press and the output is fed to the Siemens S95-U plc. The Flextop was able to react properly promptly when there is increase in temperature but whenever there are sudden drops in temperature it is slow to react. The analog transmitter (dial) was already at 25 C when the hydraulic press was shut down while the Flextop was still at 35 C. We used a three wire configuration for this. Does this have to do with our wire configuration? I know there are 2 wire ,3 wire, and 4 wire configurations for 4-20 ma sensors but I'm not sure what are their differences among them. Please see attached configurations below.     Thanks,

  24. Beckhoff and AS-Interface

    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.
  25. Programming a HMI to revert to Home Screen

    Hello everyone, I was wondering if anyone here could explain to me how I can program my human-machine interface (HMI) to revert to a Home Screen after a period of inactivity. If the user has to leave at any time, and leaves the HMI on the last screen he/she was working on, I want the HMI to revert back to my Home Screen after 60 seconds inactivity. Has anyone here done anything similar to this before? Do you think it's worth the trouble of having such a function built into the HMI? Thank you for your time and for reading.
