Hi, I need to use an absolute encoder to measure angle of turning object. I have to use S7-400 and a PVM14 absolute encoder. The Encoder support "PROFIBUS interface" and use "Class 1 and 2 in accordance with PNO profile 3.062". I am looking for example code, or a good manual. Any advice appreciated!

Hello, The company that I work for wanted me to design and build a FIFO loader. For those who do not know what a FIFO loader is, it's basically a lift that runs up and down and filling up the magazine slots with pcb's. After I finish the mechanical part i'll try to program it by using a CPM2C - 20. I have already played with CX-programmer and learned my self a bit, for example how to program simple things such as AND and OR gates for controlling motors and lights. Really hard part for me was figuring out how to create a program that reads data from the encoder and use it to create positions which the motor will stop at, and i have not yet figured it out. I've been trying to google it without any luck, the only thing of real info i've got is a 650 page long pdf file or CX-Programmer manual which is hard for me to read since i'm new to all of this. Would be great if any of you people got any source or maybe a manual which are easy to understand for new beginner like myself. A bit about the program i would like to make: The FIFO loader will have some buttons for selecting different programs, lets say you press first button to select "program 1". Then the machine should move up and stop at posision "50" (there are 50 slots on PCB magazine) after it gets signal from pneumatic actuator (which will be used to shove pcb inside the slot) its should move to position "49" and so on.. If FIFO loader is located at "home" position and you press second button to choose "program 2", then it will move to slot "49", wait until it gets loaded, and continue to slot "47" and so on.. The meaning of this is to make a loader which can select a program to fit pcb's with different size of components.

I have restored a crashed IFIX to a new PC. The restore is ok and installed GE9 driver. With the GE9 power tools, we can observed that data transmits and recieve. The problem is that the screen scada is not updating i.e. no status/feedback, anything is happening. The LAN network TCP/IP was configured i.e. IP, subnet and gateway. Any remedies/advice is most welcome. Please provide a guide on the communication/configuration setup. Thanks

I have a 16 position rotary selector switch I'm trying to program to a CQM1 PLC, that I will also be programming to a micrologix 1200 in the future, using CX Programmer. The switch connects to the PLC using 4 inputs, and activates the inputs in a binary pattern 0-16 as I turn the switch. For example: if the switch is wired to the first four inputs of the PLC, and is turned to "9" 0.0 and 0.3 will be activated and 0.1 and 0.2 will not, just like binary 9 = 1001. I have tried several things trying to get the PLC to accept these inputs as a single "data-point," and then convert to BCD or Hex to use in a timer. I'm having no luck! Does anyone have any ideas how this is done? The switch is a Tosoku DPP01 015L20RCB, and because of the age of the PLC my instruction set is limited. Thank you in advance!

Hi ! I have a question regarding the handling of the signal from the TS102 connected to my PLC. I downloaded a .pdf LINKED from "my omron", read it and put together a small program just to test the expansion unit and sensors. But I cant get any readings from the sensors and can't figure out why. I have never used a TS102 expansion unit before and would be glad if someone have an idea of what I'm doing wrong. Everything is brand new, so I'm quite sure I am the problem here..... If someone have an answer and maybe even an programming example to upload I would really appreciate it. Best Regards!

Factroy talk SE v8.0 screen problem
sachincool786 posted a topic in Allen Bradley / Rockwell Automation
Dear Experts!!! I am facing one problem in FT View SE v8.0 : I have 15 screens : 5 "are replaceable" with full resolution and other 10 are popup displays with half the resolution of that of Monitor and are "on the top" type. I have a buttons to go to those pop up screens. Whenever I press any button to open any pop up screen the background screen (Replacable type, full screen) becomes shorten and pop up displays works like they should. i.e. whenever a pop up display opens, full background screen display suppresses automatically. Then i go to another full screen and then come to the main working full screen then it becomes ok. This phenomenon occurs whenever a pop up display open (not VBA controlled). Its a simple display open button ( not VBA controlled) As you can see in the picture the back image is suppressed :- http://postimg.org/image/c5um49c5h/ Normally it comes to full screen , its like :- http://postimg.org/image/vtli1bd7f/ when I go to some other replaceable type screen and come back again to this screen, it becomes OK. Here in this pic below, you can see the properties of the screen which is giving problem :- http://postimg.org/image/gcqpkfb65/ -

Hello all, Let me start by saying that although I have been working with PLCs for 20+ years I am very (as in brand) new to the Siemens world (my wheelhouse is AB). That being said I have a Siemens S7-1500 (1511 specifically) CPU with a couple of SICK multi-turn Profi-Net encoders (AFM60A-S4NB018x12) that I need to talk to. - I am using TIA v13 with all of the updates. - I have the GSD file from SICK for the encoder. - I have no clue what I am doing - I can see the encoder values update in the watch table as I move the encoder. All fine and dandy so far... Here's where the white flag is going up.... - I am of the belief that there are existing function blocks out there 'somewhere' that can read and write to the base parameters. I have contacted our local rep who deferred me to SICK. I have emailed and left messages with them and have not gotten a return anything thus far. Here's our application... We are attaching each encoder to its own rotary gear mechanism. The rotary will need to turn in the CW direction approximately 400 degrees then return to its start point by rotating in the CCW direction by the same amount. If/When production/maintenance needs to 'rehome' the assembly, the expectation is that they 'pin' the drive in a known location then a bit would be set within the CPU that would assign a specific value to the encoder's actual position. In the SICK manual (8015078/YIX6/2015-01-16) on page 31 (section 3.6.3) there is reference to Preset control. This is what I believe we need to perform the aforementioned function. Does anyone have any examples that they could share on how to read/write to these encoders by use of a Function Block or other? Relatively desperate for help at this point. Can post test code if need be. Thank you in advance, TLAF

Hello to all Since a certain time I've noticed that the parameters values sent to the plc via IHM are not anymore recognized by the plc I'm obliged to re-enter other parameter values to see the machine working fine again. The plc reference is: CJ1M CP 21 The IHM reference is NS10 What would be the problem,? Best regards.

Hello everybody, I have a problem connecting CS1G-H CPU42 with CS1W-PRM21. Prm21 is inserted in slot 9, and i have previously made connection to prm21. After downloading configuration to prm21 i cant connect to prm21 anymore (connection to plc is working fine). The cx-configurator says CS1W-PRM21 PROFIBUS DP-V1 Master Communication Failure with UnitERH is on (red), BF is flashing red, RUN is on (green), PRM is on (green) and BST is flashing green. How can i restore comunication with the cs1w-prm21 to diagnose the problem? After some examination the problem is (probably) that i have configured prm21 to write in the adresses of CIO3000 to CIO3400. That is interfiering with other address. Is there any way to force the output of the prm21 off, or make device go in offline mode.At the power on of the prm21, i can test the connection via cx-configurator and is working and after 2 seconds the prm21 goes to stop mode and begin writing to address of the sysmac bus area. I am thinking if i can stop prm21 from writing to that area i will be able to connect and load default configuration.is that any way to stop the prm21 from automatic start? or is there a way to reset prm21 to factory settings? best regards

PowerFlex 525 overwrite my parameters/ Spd + Strt Problem
charonsk posted a topic in Allen Bradley / Rockwell Automation
Good day, I´m helping with small project and currently i am stuck because of this problem. And I hope you can help me out. I´m using PowerFlex 525 connected with AB CompactLogix 1769-33ER PLC via EtherNet/IP. Connection is working, I can read and write values from/to 525. To configure both devices i´m using RSLogix 5000. 1) First problem occurs after I loaded configuration to 525 and it´s, that 525 keeps overwriting values of Accel and Decel Time 1. It happens when i directly change parameters in Module Properties (online) or after I upload configuration to device. It happens even if i set parameters directly to 525 with its HMI panel. - I kinda get around this problem when i use Accel/Decel Time 2 for Step logic, but if i send direct reference value motor still jump to it and that is not good, especially when changing direction of rotation. 2) Second problem is that I cant get Speed Sources and Start References right. Usually Is working only option 1 and others are not, or they are doing something else that they should. For better imagination this is what i want to do: I have 3-state switch (left = 1 ON(DigIn TrmBlk 02), 2 OFF; center = 1 OFF, 2 OFF; right = 1 OFF, 2 ON(DigIn TrmBlk 03)), In center position I want to control 525 with EtherNet (already working when: Start 1 AND Speed 1 = EtherNet/IP). In left position I want to control motor directly with Drive Pot and In left position a want to start Step Logic (which i have already set) - Funny thing, If I set Start 1 = Ethernet, Speed 1 = Step, Start 2,3 = DigIn, Speed 2,3 = Drive Pot then in all three position motor goes in Step logic.. Or when i get left and right position working then Ethernet is blocked.. and this kind of things.. I Attach print-screen of my current settings, if you need something more just, tell me. Thank you for your time, and I hope someone will be able to help me. -
CompactLogix using Analog Press Encoder
jrupp82 posted a topic in Allen Bradley / Rockwell Automation
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 -
Hi guys, I have a problem with GX IEC Developer 7.04, i hope some of you can help me.

Hello, I am not sure if this topic is too far from what the forum concerns, but any advice is greatly appreciated including reference to other reference. I want to know if any induction motor has internal encoder equipped. We are using servo motors, and additionally an encoder for position check. Because the position control resolution requirement is about 1 degree, I am thinking about abandoning servo motor, and to use induction instead. Servo motor has internal encoders for outputting pulse information. And I wonder, if there are induction motors with internal encoders. Thanks in advance. Ting

I am currently trying to get my program to take distance traveled per pulse, which is based off of the diameter, and convert it into IPM. I am using RS Logic 5000 software. If anyone could help me get over this hump I would really appreciate it! -
How to conect RSLogix5000 to 1756 PLC via network
baric1007 posted a topic in Allen Bradley / Rockwell Automation
Hello all, I'm new to this forum, hope I will be able to get some answers on this forum. I'm wotking on maintanance for machines under productiona and I would like to conect one machine to my work PC. But when I try to setup conection with RSLinx, RSLinx don't see my PLC. Problem is that my PC is on network with IP addresses 192.168.8.XXX and machine is on 192.168.0.1 IP address and between is cisco RV180 routher which is set to have LAN address 192.168.8.168 (company network), and WAN is set as 192.168.0.200 (subnet 255.255.255.0, gateway 192.168.0.201, dns 192.168.0.202). When I conect directly 1756 ENBT/A card to my laptop (laptop is set to same range of IP addresses) I can see PLC and everything is working but this way is not practical for me. Is there any way to conect my office PC to PLC, some settings in RSLinx Clasic? Any idea would be helpful. I attached simplified network drawing for easyer understanding. network.pdf Thank you for your time and help, best regards, baric1007 -

I need to replace existing encoder with quadrature output which is failing. We need to have minimum measuring distance of 60 inches. The encoder installed by manufacturer is Temposonics R-series RHS0650UMSO1Q1AC10 The resolution can be lower than the current encoder, probably 500 counts/inch or higher would be OK. Do you have any product that can be used? I was thinking about string encoder but I am open to suggestions.

I am trying to setup communication between an EIP21 and a AB Compactlogix processor. Setup both units with Network configurator and Logix5000. In Logix5000 I used the Generic Ethernet Module with the correct consumer and producer tags and instances. When I go online Logix can see the EIP and bring up the module information but the connection itself is in Error 16#0114 Electronic keying Error. Unfortunately cannot find a way to disable keying like possible on the Controllogix Ethernet module. Can Anyone help. An application example or some tips how to resolve it would be great. Kind Regards Rolf

Hi Good Day, I need a suggestion, I have an omron encoder, encoder counter meter (K3NC-NB1A) and communication card RS-232C 25pins (K31-FLK1). My question is, what is the best omron software to read and manipulate the data from the encoder (I have CX-one software but I only use CX-programmer). I want to capture the encoder pulse and convert to velocity, acceleration, deceleration and also energy absorbtion. I have to use mathematical formula such as two times differentiation. I also need to show grapf and display final result that is energy absorbtion reading. Or is it much simple if I use VB / labview / java software? Thank you in advance

I need help SSI Encoder with Micrologix 1400
Angel Valdez posted a topic in Allen Bradley / Rockwell Automation
I have a project where I need to use an SSI Absolute Encoder with a Micrologix 1400 PLC. I've never done this and need help. The SSI have a Clock and Data signals that are different from anything I've ever used. 1.Can it be done using the HSC inputs? 2. I found an AMCI card I could use but I am trying to keep everything AB and in the Micro Family. 3. I don't want to use Gray Scale encoders because of the number of Inputs I have to use. Trying to package a small enclosure and don't much room left. 4. AB sells an SSI encoder but they don't have any info on hooking up to anything other than Point IO module.(kills my budget) Thanks and any assistance would be greatly appreciated. ~Angel
