  1. Hi all I have a project where i am building a bread softness tester.  To do this i am using a smc electric actuator and an A&D scale. The electric actuator will push down on a slice onto an A&D scale.  A micro830 plc is then reading the data from the scale and storing the real variable in an array 80values long.  I would like to display on the hmi (panelview800) the peak/maximum value in the array. I am struggling on how to do this though and have not found much information online. any help would be much appreciated Thanks in advance Trevor

  4. controllogix and 500 on IPAD

    Hi, Is it possible to get RS5000 or slc 500 software on an ipad to fault find and troubleshoot or even make edits.
  5. RSLogix 5000 Code Generation using C#

    I put together a demo of the c# library I am working on for Rockwell PLC. It basically allows you to parse/construct the L5X files for code generation, documentation, and other uses. https://www.youtube.com/watch?v=kV0nXSyM7Gg
  6. Square Wave Problem With Micrologix

    Hello all, this is my first post. I am using an AB Micrologix 1400 (1766-L32BXB Ser C FW 21). I was trying to generate a pulse train using the PTO instruction. I have modified PTOX funct. file. The ladder is just a simple XIO followed by PTO, (The Quick Start ladder from 1766-RM001). When I looked at the output waveform on my oscilloscope, I noticed that it wasn't a square wave. I decided to run it at several different frequencies to see how the wave form would change. At 10Hz i got a square wave. As I increased the frequency the falling edge became sloped and almost horizontal. Is this how the output should behave? The data sheet indicates a max frequency of 100kHz, but at frequencies over 150 Hz. The wave form looks like the output of SMPS. 
  7. 1756-L55/A Controller

    Respected Friends, Good day. I face a serious issue please help me to fix the problem.  We have a 1756-L55/A controller with 1756/M13 A memory card. after 2 or 3 months the program washout and the LED status on the controller are following 1. RUN --- SOLID GREEN 2. I/O--- OFF 3. RS232 --- SOILD RED 4. OK --- SOLID RED 5. BAT-- OFF 6. FORCE-- OFF  At that time CONTROL NET MODULES OK Light for Chanel A and Chanel B are also blinking and communication not established via control net and serial port AB-DF1. I switched off the power supply and after 10 second again power up the controller then OK LED becomes solid green.  i download the program and its run fine. But the problem is still there. In the controller properties the major fault shows  TYPE 01 [ POWER UP FAULT] CODE 60 [NON RECOVERABLE FAULT] what are the possible reason for wash out the program from the memory?  At that time version 16.03 firmware installed and the rslogix program convert from version 10 to version 16.03.  Is 1756 L555/A with 1756/M13 A support the version 10 firmware? i ask because the original program is in version 10 if its supported then i update the firm ware and download the original program.   Hope you will help me in this issue. Regards
  8. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 
  9. Good day, I would like to extract the FT View SE Alarm Log. We currently have got a Excel spreadsheet set up with a connection to the FTAE SQL Database.  When I refresh the data, Excel give an error telling me that the data is more than what can be displayed in a spreadsheet. So it then discards the latest data. I have tried setting a database limit in the Factory Talk Administration console to only keep the last 60 days worth of data but it does not seem to take effect. I get data from January 2017 up to 15 October 2018. Is there a way to configure the ODBC connection in excel to only give me the data for the last 30 days or is there someone that can help me to limit the size of the database? I have attached the current connection config.
  10. Hello I am  a Robot Programmer. Fortunately  I would be beginning the PLC Programmer Interview Process. From Initial CV Screening and first round of Interview. Screening was easier. But unfortunately I am not good with PLC tech questions apart from that is involved with Robot Programming. I need a few questions to judge whether the applicant is faking his experience or does he has the qualities. If any PLC Programmers can help me, It would be a great help for me.   Thank You
  11. Is it possible to add another AB Rockwell PLC to the network tree as a Generic Ethernet Module and use it as IO? Any idea where I would find information regarding assembly instance and size of I/O/C for AB Rockwell products? If possible, what are the pros and cons when compared to produce/consume and MSG instructions? Don't need to use it real world, just curious. Many thanks in advance.
  12. Clearing an Array in RSLogix

    I'm having a tough time clearing the entirety of an array. I've tried using the copy function, the clear, the fill and the the file synchronous copy functions. I'm solely trying to copy 0's into the entirety of a 20 tag array. Example Tag[0] to tag[20]. I saw another thread here: http://forums.mrplc.com/index.php?/topic/14678-clearing-an-array-in-rslogix-5000/  However, that didn't help me. Anyone have any shortcuts here?  Thanks so much in advance!
  13. Hey Guys, I'm somewhat new to Data logging so try to bare with me. I'm trying to setup Data logging in Factorytalk View SE to log to my SQL database. I have created the 32-bit ODBC system DSN. Created the datalog model in FT View Studio and selected ODBC and it created my tables fine (Float, String, Tag). I chose Login required. I also setup a File backup path. With that being said, when I use the command DatalogOn- It will start the Datalog model without any errors, but will only log to the backup path. It isn't logging anything to my SQL DB. I thought it could be the firewall blocking it so I created a rule to allow connections through the specified port. SQL is also allowing Reading/Writing.  Let me know if you guys have any suggestions. Thanks!
  14. Hey guys,   I have worked on the FTView ME platform many of times.  I am now working on a FTView SE (Local Station) application, and I am having trouble connecting an Offline .ACD file to my program so that I can design.   If someone could help me with this it would be greatly appreciated.   Thanks in advance!
  15. CIP: Forward close fault

    I'm writing an CIP-driver in C# for communication between a Rockwell PLC and a Raspberry Pi. Currently I'm debugging the Connect/Disconnect process. Everything works fine, I register a session, I start an start forward. When I press disconnect, I send an forward close to the PLC. En this seams to work. Only in Wireshark I see an error: "Destination Unknown". But I can't figure out why the destination is wrong. I filed everything in the correct order according to the table below.  
  16. Read/Write Access DB

    I am fairly new on this forum & PLC's, usually i read and get tips from here.I use a RsLogix 5000 PLC software. I am currently working on a project at home that requires me to read from a Access DB. What type of Instruction or method do i go about, initially reading from Access? I know Excel is possible It's an existing system. Add on functionality/feature. I am using a barcode scanner that will link up to a Access DB to verify the barcode is legit and send this info to a different system via PLC/EthernetThe access DB is used because its a older system, it uses that. So it is possible? and guessing from what your stating, its is more involved to get the system working eventually?PLC = A&B 1769-L23-QB1 CompactLogix Controller I am using FactoryTalk View Studio as HMI, do not have SCADA.I have a control logix chassis. Thank you in advance...
  17. SLC5/05 upgrade

    I'm being asked to come up with ways to upgrade an old 5/05 rack. A few years ago I thought I remembered Allen Bradley having a special rack that would allow a new processor control various old IO types. Does anyone remember the name of that system? and has anyone used it? We will probably replace with an Automation Direct PLC (per their request) but, want to offer an Allen Bradley solution as well      
  18. FactoryTalk SE - VB Script

    Hey guys,   I am looking to query a database through FactoryTalk SE.  I will be scanning packages, and using that bar code to find a lane assignment from the database.     My question has to do with where the VB script will reside in the FactoryTalke SE program.  I want this script to run at all times.  I see that each screen has a "VBA Code" but I am assuming that these will only run when the screen is visible.   Where does this have to be stored in order to run all the time?   Thanks In Advance!
  19. tech connect follow up email

    I Was wondering what other people do in regards to the follow up emails that rockwell support sends out after you use your service agreement. I try and fill in all the questions and give good feedback but i have also ignored them all together and never heard anything else. For the record I am a big fan of the rockwell support it may take several calls to get a problem resolved but they have never let me down.

  22. Micro 830 RTC programming

    Hi all,  Can someone please help me, I am using a Micro830 Controller running connected components workbench software to program the controller. I want the use the Real Time Clock of the controller to control an output to turn on everyday at 01:30am and turn of when it receives a signal from an input. The output will control a backwash valve that will operate and activate a cam switch internally that sends a signal back to the Controller to say the valve has operated and can now stop sending the signal to the valve. (if that makes sense). I have tried playing around with the RTC instructions but I cannot seem to get it to operate how I want it to. Any help would be much appreciated. EnvrioService
  23. Kinetix 6500

    Hello All, I'm completely new to the motion control systems and I'm interested in learning servo programming and motion control.

What is the best way to learn it. If you guys have any resources or basic sample program please help me. Any learning material would be helpful. Thank You All
  24. Hi everyone, I want to receive signal  from E+H flow sensor to Rockwell PLC( module MVI69-HART attached to PLC). I tried to use local 4 which is new local opened when I added successfully MVI69-HART(INT type variable) but it not work. Sensor's monitor display mA values (4mA -> 20mA).  Could you please show me how to receive mA signal in PLC software or give me some documents related to this issue?  Thanks. Have a nice day. ^^
  25. Gentleman…   Does Rockwell have any simulation PLC code that mimics an SMC-Flex soft starter?  Since we are using those (as well as the E3+ and E300) I would like to develop a model environment for starting of several drives.  In a specific case, we may have 3 or 4 drives in a pool of drives in which only a subset must be running at any one time.  Development of ladder logic for starting and maintaining those drives running while considering various fault conditions and startup issues would be very helpful in our environment.  I would like to be consistent among various areas within our plant that we incorporate pools of drives, from 4 to 2.  Having the ability to test in the lab would be very beneficial.  Thank you, David
