  1. Greetings, I've been having some issues with a vacuum pump breaker tripping... I think I've figured out the problem and resolved it but I noticed that several of the other motors have current monitoring on the HMI but the person who set this up is no longer with us.  I'm wondering what I need besides an analog input for my control logix processor (which I have) to setup this project.  I'm not sure if the other motors are just monitoring one leg of the 3 phases or if they are somehow showing total current?  any ideas and recommendations would be greatly appreciated.   thanks,
  2. First post. We recently upgraded our machine from an SLC to compactlogix. In the SLC 5/05 we used analog 1746-ni8 cards for pressure and position sensors. When we moved over to the compactlogix 1769 l36erm with 1769-if16c cards we seen issues where the analog values had very little definition accuracy. This can be resolved by changing the filters but then the response time of the card is to slow and we miss data. All of the relevant code from these sensors are in their own task and ive tried periodic, event and continous tasks but none of this helps. The strange thing is with the SLC we never seen these issues. Any ideas how i can improve the reponse time when the filters are set low?
  3. Have a PLC5 project with remote racks with digital and analog I/O. For test purposes have wired AO to AI and have set up the BTW and BTRs. Problem is I put a value in the N11 register for the particular AO (N11:66 - BTW) and it doesn't appear in the other N11 register for the particular AI it is wired to (N11:4 - BTR). The AI - N11:4 continues to read a value of "8259" in decimal/"2042" in BCD, despite any value I put in the AO N11 register. The range of the AO is 4-20 mA with a Raw min of -4095 and a Raw max of 4095 and the range of the corresponding AI is 1-5VDC/4-20 mA. If I remove the wiring arm of the AI, the N11 register will read "4135" decimal. Would appreciate any fdbk as need to get working as system for customer will not be migrated to newer RA or Siemens system til next year. Cant get support out of AB for questions as only have standard "tech connect" tech support contract and PLC5 requires you to have "Legacy automation" tech support added to your "tech connect" stnd contract.

  4. PLC Programmer Job

    dan.dumitrasc posted a topic in Siemens

    Hi there! I`m a PLC programmer from Romania and i work in automotive industry. I know to program in Step 7 and in Codesys. I`ve been working with S7-300 from Siemens and Wago 750-881. I am also designing the electrical drawing for my project in a software called WSCAD. I am trying to leave abroad because i have a low salary here and i am wasting my knowledge. Can anyone give me an advice or help me with finding a normal paying job in plc programming? Thank you very much in advance and have a really nice day!
  5. Hello! I have a PLC S7-1200 (1212C DC/DC/DC) and a few question about programming S7-1200 in TIA Portal v13. 1. I want to make "upload station", because I am not surre whichone project is the last. But, when I start upload data, the error hapens, and the decription of error is: The name of the station "S7-1200 Station_1" is already in use in the project. How and where can I change it? 2. And the last question: I try to connect my S7-1200 and Weintek simualtion. There is all time :"PLC not connected". I have chceck everything: PLC is OK, communication PC-PLC ok (ping ok), windows firewall off, administrator rights ok, configuration made with manuals, (CPU - Siemens S7-1200, IP: 192.168.1.100, port 102, tags import - ok.) I have read the manual many times, and check settings - nothing change. Maybe have someone problems like this, and found a solution?

  6. Greetings, I'm ok with RSLOGX 500 but am an absolute beginer with RSLOGIX 5000 and was wondering if anyone had any simple sample code just to study. I would love something using analog input and or analog output. thanks in advance.
  7. I am converting a PLC-5-40 processor that also has a SST side car for Profibus Dp communication to BK3100 modules on the equipment. To a Control Logix L-72 processsor using a Molex SST-PB3-CLX card to the Profibus modules. Everything went some what smooth until I got to the SSI transducers in the Profibus. The word arrangement is not coming in the same as with the PLC-5. Is there anybody else that has run into this problem and is there a solution. I have contacted Molex, Balluff and Beckhoff the first 2 got back to me I am still waiting on Beckhoff.

  9. I'll set the scene a little before I explain the issue that I am having. I have an application where I have a Linear Servo Slide acting as a Press Kick-off cylinder on a ceramic press. In order to trigger this Slide accurately, I have installed an Absolute Rotary Encoder (a Turck product) to the press, which outputs an Analog signal for its specific position. I then have this as an input into my CompactLogix L33ERM through a 1769-IF4 Analog Input card. Within my code, I'm trying to capture the moment where the press has presented the part out of the die and it can be ejected from the press cavity without damage the part. Mis-timing on this ejection and the part will clip the die pad tooling and incur damage upon ejection. Now, one last point of clarification, I am a Mechanical Engineer by trade, so I don't claim to be an expert programmer. But I have learned a lot and have gained experience in programming applications like this, so I can learn quick and should be able to program this task. I have had my local Allen Bradley guy look at the code I'm using for this application, and he thinks it looks good, but I'm still having issues. What I have done, is within the code, I have a window that I look for, of the encoder's position, to trigger the ejection shoe to fire its sequence and kick the part off. However, I have had to make this window so large in order for the code to see it every press cycle, that occasionally, the ejection shoe will be fired at the back end of the window, which is actually too late, and my part is being damaged. Attached is a snapshot of the code. The OkSamplePress.DN is actually a timer that I have that looks at the current press rate and puts a delay in to not allow the kick-off to fire too early, because I was actually getting a glitch before where the kick-off would fire prematurely for some reason. I don't know if anyone can offer assistance on this or not, but I would greatly appreciate any help at all. Its become quite frustrating, as the rest of my machine functions quite well, and this seems to be the nagging issue I can't get rid of. Thanks in advance...Josh
  10. I've got a PLC stack with a Q64AD analog-digital converter card. I am attempting to read the digital output value of channel 1 but I am having issues. First of all here is my simple PLC program: I got the program from the Q64AD user manual. You can see there is a blue '0' on the right of line 0. I assume this is the value that is being read? When I monitor the D11 device in GX Developer it shows a '0'. The following is a screen from Online > Monitor > Buffer memory batch. My card has a base address of 0x60 and channel 1's offset is 11d (0Bh). The value on the highlighted line does change so I know that the analog card is correctly picking up on current changes from my source. Lastly here is an image of my digital inputs. I have set up the Q64AD card through the GX Developer PLC Parameter window and left all settings as default. I initially used 'K11' instead of 'H0B'. I have also tried using the MOV command (MOV U0\G61 D11) but that game me the same result. Can anyone spot the flaw in my program of configuration? Do I need to configure the PLC in order to use the 'D' devices? Should I try copying the value somewhere other than D11? Thanks

  11. AI and DO Data Acquisition Unit

    Omar27 posted a topic in HMI & SCADA

    Hi, I am looking for a Modbus TCP based AI and DO data acquisition module and scada program. The analog inputs are 4-20 mA . SCADA should be able to communicate over Modbus TCP( I think every SCADA does that but just want to make sure). Can you guys please suggest if you know something good fit my application? Thank you,
  12. Hey guys, so I feel like I must be doing something wrong here, well obviously since I cant get it to work. So I have a CompactLogix L36ERM running RSLogix5000, I've got 28 cards in total, all working except for one. My 1769-OF8V Analog Ouptut module. I just want to be able to output a 0-10v signal to a proportional valve module, specifically a Parker PCD00. Anyways, so I am online with the processor, everything is looking good, I/O is responding. I have the specific channel on that output module enabled in the module properties. I have tried changing the data type to every different option, I have raised and lowered the limits. I think I am addressing it correctly. I am just trying to move a value into that channel's data file. It appears to be moving the number in just fine, but when I put a meter on the output for that channel, I get 0V from the output to analog com. There is a little switch inside the module that allows you to use rack power or external 24V, I tried switching it down and using an external 24VDC source, I currently have it switched up to use the rack power. I'm lost. If somebody could please help me out and tell me if there is something obvious that I'm missing or doing wrong/ take me through an easy step by step way of setting this up for basic 0-10v output, that would be great. Sorry for being so new, I have attached a couple screenshots of the logic I'm using and the way I have it configured right now, but I have tried all different configurations. Thanks, Howard
  13. I'm new to Omron, and after several days of diving into manuals trying to figure this out on my own and giving myself a headache I've come to accept that i need help. my task is the following: Control of the discrete and analog inputs/outputs in a DeviceNet system using an Omron CJ1M PLC’s and PT’s. Use at least one thermocouple, one analog input, and one analog output for the DeviceNet network. Use a pushbutton and a light for the start of the process and an indicator for the started process. I have a Drt1-Ad04 input, a Drt1-ad02 output, and a Drt1-ts04t temperature control. My devicenet is Cj1w-drm21, The Omron system itself is a cj1m-cpu13 etn21. I have node addresses for my input, outputs and temperature control, those being 35 for input, 25 or 30 for output and for temperature control 5, 15, or 20. The ip address im using for this project is 142.214.143.9I'm using Cx programmer, Designer and Integrator. On Cx programmer I've managed to create an IO table but i have no idea on how to begin the program or even get a current reading from my generator.On Designer I've made what i believe to be the layout of the pushbuttons, I just have no idea of what addresses to enter.And on integrator i'm having troubles on figuring out how to make a routing table. I've went through many manuals and either i'm missing something really basic here or I just have no idea on what I'm doing. The only advice I was given was to dive into more manuals and find my addresses for my inputs, outputs, and temperature or to find the information from an outside source be that a forum or customer service. I am able to provide more information, and screenshots of what I have done if needed. Any kind of help would be greatly appreciated!

  14. Panasonic FP-X C30R

    jaymac posted a topic in Other PLCs

    I'm very much a novice to plc programming. I've dabbled in years past with Mitsubishi FX units with Medoc long before G X Developer became available. I also did a bit on Schneider using Zelio software. All very much simple stuff using ladder logic and internal relays But I've got me a Panasonic PLC that is surplus to requirements where I work and I would like to investigate the possibility of using it for practice purposes. Who knows, I might even get it to do something useful. I expect it is a few years old - its got a version No 2.4 and what seems like a date on it 080916. First query - is there software available for this item. Second query will it be compatible with a computer running on Windows 7. I've checked on the internet and see that there is documentation out there the plc. I decided ask for some informed opinion from before I go too far into what turns out to be a "cul de sac". Regards jaymac.

  16. Hi everyone! I have this simple problem, but cant get over it. I have structured ladder/FBD Project and i use GX works2. As topic tells I use analog signal from field. Now, i need to compare this value X (from field) to Values X1 and X2, meaning if value X is between values X1 and X2 then M1 is true. Ok, but what function i need to use for this? Best regards, Juha.

  18. 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

  20. 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?
  21. I need to set up D/A module. I have few questions. What is the difference between offset and gain setting mode? I would like to use range 0 to 10V which would have to be set as user range setting, can I do it using GX Works 2? Or do I have to use the GX Configurator-DA package?
  22. Hi everybody, I am new in these issues and I have faced a problem that is driving me nut. I am building a mixing batch HMI and its PLC program. In my HMI I created an analog tag that stores and integer number. This tag is responsible to comunicate with an analog input of the PLC I/O expansion module, whose address is I:1.0. In my HMI I put a numerical input box to send values to this analog input, but every time I write a value in this box and press the enter key the numerical input box gets red and don't send the value to the plc. Appear the following error message "cause: Addressing problem or memory protect rungs" on the left botton corner of the HMI. Some pictures are annexed to describe better. Anybody knows what can I do? I am using PLC SLC 5/03 + Analog module 1746-NI4

    Any one out there have a programmer for one of these old PLC's or can any one recommend some where I could send one and have the program printed off for trouble shooting ? Thanks !
  25. Hi All, Im sure this has been covered before... Im using a ML1500 and a 4-20ma output flow meter. Due to the erratic flow in the line the analog signal is all over the place. What is the best way to smooth this signal out so I don't see all these variations..??? I don't have a CPT instruction on the ML1500 but there has to be a way. Just looking for the way you guys do this that gives you the best results. Thanks
