  1. RS5000

    Shiner posted a topic in Allen Bradley / Rockwell Automation

    Hello all, I am trying to get around a lot of manual inputting by exporting a routine and opening it using excel, but looking at the file that excel shows I have a couple fundamental questions 1. when excel opens it and "creates a schema', can I save this in a format that will allow me to import it back into the program? 2. Since I am mapping data using add on instructions, the table excel has created becomes quote complex, with no clear point of reference to where my Input tags are going to go. We are doing this because someone thought it would be a good idea to put a SCADA based control platform over the top of an AB control system, so we have to exchange thousands of points of data back and forth with their system. I created the mapping AOI blocks to be able to manage the file structure a little better in the routines, but that still leaves me with copy and paste thousands of tags into the AOIs. Has anyone developed a good way to create logic, or modify logic using excel? While I can hold my own with utilizing the RS5000 platform, my excel experience is limited. The processor is a 1756-L75 Thanks
  2. I wish to send a temperature set-point from an Allen-Bradley SLC 5/05 (Ethernet) PLC to a water temperature controller and read back the actual value. [ PLC ]<---------->[ Temperature Controller ] The temperature controller RS485 comms supports protocols for moulding machines from Arburg, Battenfeld, Billion, Demag, Dr. Boy, Engel, Frech, Husky, KraussMaffei, Netstal, Sumitomo, Toyo and ‘Spezial’. They have given me the details for Engel’s Interface Protocol P2 which is 8-bit ASCII. Question: What's my best option for this? Buy a BASIC module? [ PLC ] [bASIC]<---serial------->[ Temperature Controller ] Use the serial programming port directly? [ PLC ]<---serial------->[ Temperature Controller ] Use an Ethernet message to some external programmable serial server? [ PLC ]<----Ethernet---->[serial Server]<---serial--->[ Temperature Controller ] I've modified and debugged A-B PLC code but I'm not very familiar with their hardware. Many thanks.

  3. Omron CJ1M-CPU13-ETN to .NET Framework

    BitsNBytesRookie posted a topic in Omron

    Hello People, In my school we had an assignment to program a Sorting machine using an Omron PLC and CX-Programmer. Now we got the assignment to make an HMI that we can open on our own computer (Windows 8.1) so that we can control various things of our program, such as reading and writing bits, and other data (To the PLC obviously). Now I only have very little experience in reading and writing data from a PLC (Using a PC), I have used the libnodave library to connect to a Siemens S7-300 PLC. With this I managed to read and write bits, and also read and write data to a DataBlock. We wrote this program in Visual Basic 2013 using the .NET Framework with the libnodave library as an added extension. Now I have searched far and wide on the internet but have not come across any good examples of how to do this with an Omron PLC. So I hoped that I could get some advice from you guys. What I'm asking is if anybody here has maybe a link to a guide/ example program/ manual that could get me forward? And if I can easily get this done with Visual Basic, by adding an extension, could anybody tell me which extension this would be? And where I could find it? I appreciate any help. :D Thanks in advance, BitsNBytesRookie
  4. Hello Everyone, I am new to ladder logic, and trying to understand flow of below attached ladder logic- How does the program flow ? Does PT4601_I in rung 3 waits for rung 2 to complete inorder to consider updated value of PT4601_I or it consider PT4601_I default value and runs simultaneously with rung 2 ? Thank you in advacne

    Hi All, I have problem about programming serial module Mitsubishi PLC using QJ71C24N. If I unconnect the cable from the module and connect again it show SIO error and the communication become lost or not sending data again. so i have to restart the PLC to make it normal again. Any other solution for solve this error without restart the PLC? Thanks Husanto

  8. PLC Integration by SCADA

    Jairus posted a topic in Siemens

    Hello Experts, Good day to you all. I just can’t figure how I will integrate five S7-300 PLC. CPU 315-2dp. (1.Blow moulding-> 2. filler-> 3. labeller-> 4. packer-> 5. Palletizer) I just want to get the speed of its machine, the output rate and the alarm, this is purely monitoring, archiving, no need to control anything here. I planning about SCADA system. I’m thinking if I could do the same way in my previous project, which I’ve done in profibus master/slave for two s7-300. But this time the five PLC’s already set the profibus as master to the danfoss drive, sew drives, ET200s and many more profibus slave. I plan to buy 1 PLC as master and I will set all as slave, but how since all the five existing PLC, its profibus already configured as master. Thank you very much. All your inputs is really appreciated.
  9. Hello, anyone know how to make a logic that monitors the change in position of a carriage through some rails ?. In my application I measure the position of the carriage by means of a laser sensor and I have to detect if the laser beam is interrupted when the carriage is stationary or moving. I have implemented a logic as the adjunct file, but doesn't work.

  14. In my program, I have about 100 rungs for 100 faults. Each rung looks very similar. I thought I could make the code more maintainable by using function blocks, to avoid having to change each rung individually (if I needed to). Would it be best practice to create a new instance for each fault, or to reuse the same instance for each fault? I come from a C and java background, so I am confused as to whether a function block is supposed to be like a function (in C), or supposed to be like a class (in Java), or neither...
  15. I'm just starting to learn Ladder Logic Programming. I'm using Allen Bradley RSLogix 5000. I've been tasked with developing a 'Simple' Coffee Machine which operates like so: Toggle Push Button to StartDrop Cup (for 10 seconds)Feed Hot Water (for 10 seconds)If required, Add Milk (for 10 seconds)If required, Add Sugar (for 10 seconds)Procedure Complete - Illuminate Complete Light (for 10 seconds)I have implemented everything except the OPTIONAL add Milk & OPTIONAL add Sugar. Options are: To have a Coffee without either Milk or Sugar.Or have a Coffee with Milk and Not Sugar.Or have a Coffee with Sugar & Not Milk.Or have a Coffee with BOTH Sugar & Milk. I'm considering using Toggle Buttons to select / jump to a Subroutine (choosing the required ingredient make-up). But I'm wondering if there is another way to sequentially go through the procedure? Thanks. http://stackoverflow.com/questions/26930902/ladder-logic-simple-coffee-machine-optional-add-milk-add-sugar?noredirect=1#comment42839041_26930902
  16. Let me set the scene. I am inside my function block. I would like move an internal integer into an integer that belongs to my program symbol table. I would like to do it inside the function block, so that the function block is self contained. i.e. it does not need any extra inputs/outputs in the function block call. Is this possible? If I was writing this in Object Oriented code, I would just write this within my method: myGlobalVariable = myLocalInteger; and that would be that...

    There are two Proficy ME projects in the zip file one for VersaMax and one setup for 90-30 CPU364 but is the same for all of the 90-30 processors, but read the Manual GFK-2220 to get the correct port information for your CPU and configuration. They are both working and well documented. They were done quite a while ago but I do not recall what version of PME is needed to open them. It is my recommendation that we all use the latest version. Good luck and have fun with it. R~ <))>(

  20. Hello all, I am trying to download a new program to a AB 1746-BAS SLC 500 BASIC board via RS-232 connection through a Windows 98 laptop running Hyperterminal. While the BASIC board is connected I verify connection by waiting for the board to print out its information in the Hyperterminal program and then enter "CLEAR", "NEW" and finally, "LIST" in Hyperterminal to wipe any program from the board and verify the board is clean respectively. Then I load the new program via a .TXT file using the "Send Text File" option within the Hyperterminal program. After the program has finished loading I than type "LIST" to verify it has copied over correctly. I than switch the SLC over to "Program Mode" via the key. After doing so I type "RAM" to select the program i just uploaded to the BASIC board and then type "PROG" in the Hyperterminal program. I than receive the "Programming Sequence Failure". If anyone has any advice as to what I am doing wrong it would be greatly appreciated. Below is a list of everything I have set and researched. Thank you in advance, James -Laptop: Windows 98, Hyperterminal -BASIC board (programming): JW1 pin: 1-2 3-4 JW2 pin: 1-2 3-4 JW3 pin: 1-3 2-4 JW4 pin: 5-6 3-4 -RS-232 9-pin connector: Pin 2 connected to Tx Pin 3 connected to RX Pin 5 connected to ground Pins (4/6) crossed DSR/DTR Pins (7/8) crossed RTS/CTS -Hypterminal: Direct Com1 bits per second: 1200 parity: none stop bits: 1 Flow control: Xon/Xoff Settings/properties: -> Emulation VT100 -> ASCII line/character delay: 30 milliseconds check box: Append line check box: Wrap lines... -Manuals: 1746-rm001 1746-pm001
  21. hello guys I'm working on a project that requires knowing the first event that put on alarm state to one system and because everything happens in seconds and everything shuts down almost the same time it is very hard to tell the operator what was the cause of the shut down , so I would like to know how to implement a logic to capture within milliseconds the first event that "turns off" the whole plant. Would somebody could help me with this please?

  22. Buy what PLC?

    edvinfors@yahoo.se posted a topic in General Topics - The Lounge

    Hi I want to buy a PLC and additional required stuff, to play with at home. Where do I find cheap PLCs? What software do I need to make this work with a Windows 8 PC? What other physical interface and software is needed/recommended?
  23. I have the following situation; I have a distribution network connecting about 400 RTUs, using 101 protocol to connect to their PDH MUX, which data slot is transported using SDH STM-1/4, to the Primary Substations. Then the primary substations connect to the LDC building using STM-16. At the Control Centre Building where the Front End is located, there is a STM-16 node with some PDH ports, but definetly not 400, so how can I extract this 101 asyncronous data channels to connect them to the SCADA Front End? Note that conversion to 104 is not allowed by the client. Thanks in advance!
