  1. Hi Here's a question I'm about to ask Omron.. as soon as I can figure out who to ask.. It's complicated asking support.. their web email form doesn't make complex questions easy. Here's the question: Can the NJ CPU program a LinMot linear motor to make the "Random Sea"? The NJ has a mixed protocol.. Ethernet/IP and EtherCAT (CoE),  and claims to be a "Motion Controller".    I doubt Motion Control is available on it's Ethernet/IP line.. but the EtherCAT might be another story.   Certainly The Omron NJ is a Motion Controller for Omron NJ series drives.. However, how well does it work with LinMot? Here's the curve.  Imagine a LinMot Linear motor continuously moving, never really stopping, following a real-time, mathematically generated curve, moving positive then negative, at random frequencies and random amplitudes. Almost never repeating a motion sequence. looks something like this: Yet, after a while the motion history fully represents the spectral distribution of energy on the surface of the ocean. Spectrum analyzers can display it, and mathematics can define it..  I just have to make that sea in a model scale…    (Time scales by the square root of the scale factor) And keep the water in the tank: https://www.youtube.com/watch?v=SQd6YzBWVvI The big question is: Can the Omron NJ get a LinMot Linear Motor to do this? … LinMot thinks YES.. but, isn’t sure. Yes there are ways to “connect" LinMot to The NJ.. EtherCAT (CoE), Ethernert/IP but… there is nothing in the LinMot drive that can create or store a predesigned Random Sea .. Only a Motion Controller, generating real time motion commands, by running  mathematical equations, "on the fly” can do that.   If the NJ is a true “Motion Controller”, and the LinMot C1250-DS-XC is implemented as an “axis” by Symac Studio, which it is…       Then, there may be hope. Closed loop, PID feedback remains with the LinMot drive, with special settings in LinMot Talk … Homing might have to be done with the NJ .. or by Digital I/O’s What do the Omron experts out there think?  Can this be done? Thanks much, Regards, Michael
  2. Hi everyone ! I have a little project wich involves communication between two Micro820 controllers via TCP/IP. To do that, I started to work with TCP/IP socket. Within CCW (Connected Components Workbench), I tried to create a new socket instance using the instruction SOCKET_CREATE and set the socket address to 127.0.0.1:21. Basically, my computer through the FTP port. The problem was that it couldn't create a new socket instance (error variable is set to TRUE and status is set to 4, wich I don't know the meaning) because I didn't have a server-side application that listens to TCP/IP socket requests. That said, I found an open source application called SocketTest that listens for TCP/IP socket requests on a specified IP address and port. So, I started a listener on the following address : 127.0.0.1:21, but the error variable is still set to TRUE and status is still set to 4. So, my questions are : Is my IP address OK ? Is my port number OK ? What means the status code 4 ? Is SocketTest doing what I think it does ? Do I need to do something else before using the SOCKET_CREATE instruction ? Thank you in advance for your help !
  3. Hi everybody, Recently, I started working on a project. I want to develop a program for a Micro820 controller (2080-LC20-20AWB) using CCW (Connected Components Workbench). I built a little motor circuit for testing purpose. However, after building the program and downloading it to the controller, I tried to connect to my controller via CCW, but I can't. When I click the button "Connect", CWW crashes OR a window saying : "The controller has unnacepted changes" appears and asks me if I want to "Download current project to the controller" (wich I already did) or "Upload the project in the controller to overwrite current project content" (wich is grayed out). When I choose to "Download current project to the controller", CCW starts downloading the resource, but fails. In the "Output" window, there's a line saying : "Download failed for Device:Micro820: An error occured while reading from GETACTIVERESOURCELIST.". The problem is that there's no documentation at all concerning this error. I even tried to reinstall CCW, but it didn't fix the problem. I joined some images so you guys can see what I'm talking about. Don't mind asking for more details !

  11. Hi guys, I'm in the middle of a little university project, I'm attempting to implement a control system purely based on artificial intelligence. A neural network will be used to map the characteristics of a power plant. A fuzzy logic controller will be used instead of the conventional PID and finally a genetic algorithm will be used to tune the controller while the system is online. This is all simulated of course. Each of those AI's will be developed in Matlab. Only problem with that is, is it outputs the code in C or C++ (From memory). I would have to convert this to structured text (Based on Pascal). So to circumvent this problem I thought I would just directly interface matlab to the PLC (Schneiders M340).  My idea being, all the calculations are done in matlab which are then sent back to the PLC. However this presents me with a new problem of how I would be able to interface matlab to the PLC. If anyone has experience with this sort of connectivity, any advice would be greatly appreciated. Thank you in advance, Luchek
  12. Hi, I am using syswin and i am doing an exercise on saving and moving data. My challenge is am monitoring temperature from a sensor and the range is -20'C to 100'C from the 4-20mA sensor, after conversion and testing for positive and negative the values are stored in D205. (I have done the conversion and testing for positive and negative values only assigning of bit 15 in D205 is left) The simple program has to turn on Bit 15 if the value is supposed to be negative. 1000 0000 0000 0001, a simple approach to telling us this is -1’C.  0000 0000 0000 0001, is telling us this is 1’C. Bit 15 is going to be our Sign Flag, so we have to ensure that if the temperature is positive then  Bit 15 = 0, how can we do this make Bit 15 of D205 = 0? If the temperature is negative then  Bit 15 = 1, how can we do this make Bit 15 of D205 = 1? How can i turn on this bit inside a data word? for negative i thought i could just add #8000 to the values after conversion then storing in D205 but for positive values how do i ensure that bit 15 is 0? How could you approach this? Am a bit stuck, all thoughts and ideas are much appreciated if possible you could add a snapshot from syswin or cx-programmer. I have attached the WTANK.SWP file which can be opened in syswin or cx-programmer. Look in block Main 8 Temp Buffer, Network 3 Convert to 'C WTANK.SWP
  13. There are a lot of instructions in function block that are missing the enable input that is present when programming in ladder logic, such as  ADD or MOV.  It seems to be very limiting. The only way around it that I know of is to write your own function block in ladder logic or statement list and use that. I seems rather limiting of a language if it relies on other languages for it to be usable. Does anyone know why the enable bit was left out in many function blocks when it is so useful in ladder logic? Pat

  20. 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.

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.
  24. Hello!! I am a beginner in PLC and Automation. I have built a ladder logic program in RSLogix 5000, the controller I selected is 1756 L62 ControlLogix 5562. I want to test my logic. I have installed RSLinx Classic Lite already. Can I use RSLogix Emulate 500 (free downloadable from Rockwell Automations) for testing my ladder logic?
