  1. 3 It has been decided to introduce a Programmable Controller into a manufacturing plant to control a three phase induction motor via an autotransformer in order to reduce high starting currents. It is required to include an alarm circuit which is to give an audible and visual alarm when the motor is overloaded. A momentary actuated Reset push button is to be included in the alarm circuit which will turn off the audible alarm but leave the overload lamp on until the motor overload is reset. Once the motor overload is reset the overload lamp is to be de-activated. The conventional relay circuit diagram for this starter is shown below. A single Stop/Start push button control station is required to initiate the following motor control sequence. a. Motor 1 turns on the instant the start push button is operated; b. Motor 2 turns on 10 seconds after Motor 1 starts; c. Motor 3 turns on 15 seconds after Motor 2 starts; d. Motor 3 turns off after running for six seconds; e. Motor 2 turns off 6 seconds after Motor 3 stops; f. Motor 1 turns off 3 seconds after Motor 2 stops. If the Stop push button is operated, or a thermal overload from any motor is tripped, the whole system will shut down. Motor 1 will start the control sequence again next time the Start push button is pressed.
  2. So I was out in the field a few days ago and encountered an issue I have never run in to before on a Micrologix 1400 using RSLogix 500. All was going well when I was checking the I/O's until I realized that although I would get an input, the virtual output (B3) would not turn on... I have encountered something similar in Siemens programming where if you accidentally have 2 coils using the same register, they act as an AND instruction. When I was completely stumped I decided to make a completely new program and just put a few inputs and a few coils in, and everything worked fine... Could this be some sort of memory overlapping issue I am having? Any advice or tips would be greatly appreciated.
  3. Hi, I'm new to this forum and relatively new to AB PLC's. I'm trying to setup a PID Loop to work with an HMI. I understand that SWM is the preferred manual control method. My problem is that when I set the "PID1.SWM" bit it immediately resets. Nothing in the logic is resetting it and I have tried forcing the bit on in the logic. I'm using a 1769-L36ERM processor with Logic Designer 5000 v24.
  4. Hi This is my first time using AB PV 600 and panelbuilder32. I do not have the original CD since it was bought long time ago. I am looking for few examples to configure this HMI to display a simple welcome message and is there a way to conenct an access database to the panelbuilder32. Thanks

  6. Hello all I have an Allen Bradley industrial PC, Part number 6182-AGAZZC First of all, has anyone got a copy of the CD with the OS on [it runs on Windows CE 3.0] I need to reinstall the OS but i cant find the CD with it on, tried contacting AB but so far i've had no luck Secondly, I've been asked if i can copy the program off one 6182 onto another [the old one has a bad screen and some comms faults, so i've been asked copy the files to a new working unit] I tried using a pcmcia card but it doesnt copy over all the files for the program, and i dont have the pc with which the program was made originally Is it possible to copy the program over via pcmcia, or copying the DOC, or anything? Thanks
  7. Hi All, I newbie in allen bradley usage. I am trying to configure 1756-SYNCH profile in RSLOGIX V21. According to help of "Associated Axes" tab, Axis 0 can support AXIS_SERVO, AXIS_SERVO_DRIVE, AXIS_CONSUMED, or AXIS_VIRTUAL. To cross verify, I have added AXIS_CONSUMED in my project but AXIS_CONSUMED tag is not showing in axis 0 choice selection. Can you guys please help me why AXIS_CONSUMED is not showing in choice selection of axis 0 and axis 1.

  10. I am trying to use my RFIDeas pcProx plus reader with my micrologix 1400. I know that the 1400 can send and receive strings. I want to read in the id number from the reader and send it to an external database. Can someone please point me in the right direction? Thank you
  11. I have a 2 axis control that runs a pair of identical servo drives. as of late I have been getting reports from the operators that the two motors, while jogging forward will suddenly run in the reverse direction at a high rate of speed. There is not a reversing function on these axes in an way. I am suspecting there may be a problem in the analog output of the module causing an inversion of the signal which in turn causes the motors to run in reverse. This setup has been in operation without any instance of this happening for around 5yrs before any issue with out of control runs. All cabling has been checked and is properly shielded and grounded.
  12. 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
  13. Hi all, While upgrading HMI from PanelBuilder32 to FactoryTalk View I encounter a problem using I/O to interface with a PanelView Plus. The communication is defined in RSLogix 5 program as Rack 3 group 2 Size 3/4, range 32-37. PLC communication with the panel is not changed, but buttons in old PanelView using I:34 and I:35 work, in the new PV+ they don't, all bits remain zero. Block transfers Read and Write are all sending data to rack 3 group 2 module 0. While testing I noticed O:32 is used as status bits by the Block Transfers - maybe inputs I:34 and I:35 are also used for somethings similar by a new PanelView Plus? Thanks!
  14. 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
  15. I have a project I am starting and I have to be able to wind a small diameter wire onto a 1/16" shaft, .5 to 1.5" wide and 13 layers at a max speed of 2,000 rpm. Is there anyone who has done something like this and have some sample code? I am gearing 2 Kinetix 350 drives with 2 AB servos.I have a separate tension unit that I have to communicate via RS485. Not to concerned about that. As the coil winds the traverse will move the wire back and forth.
  16. Trying to add points to a QLC link from WDPF to SLC5/04, incorporating a 1770-KF2 DH+ interface module. This link has been in place for years, incorporating only DCS reads (both digital and analog). We recently added several more DCS reads successfully, but cannot seem to get digital or analog DCS writes to be seen by the registers in the SLC5/04 data table. Could this be a limitation by the 1770-KF2 module, or is there a more probable reason? SLC5/04 DH+---------1770-KF2---------QLC Could Duplex settings on the 1770-KF2 module have a bearing on this dysfunction? Successful DCS analog reads PT101, N9:2, A0000 PT102, N9:3, A0002 DP103, N9:4, A0004 Unsuccessful DCS analog writes PV101, N9:18, A0500 PV102, N9:19, A0502 PV103, N9:20, A0504 Any insight would be greatly appreciated. Thanks.
