  1. Hello, new here but i have experience programming unitronics PLCs. A year ago i program one Vision 700 PLC for an oven. The program manage the oven and record temperatures. When the process ends. PLC send an email with the recordings. After three months with daily use the PLC stop working correctly. The user cant change the variables throught HMI. When touch the Variable box in HMI to change it nothing happened. The touch screen worked fine and user can touch other HMI Buttons but not Variables. What i did was zero all the PLC operants to default. Then everything works fine.After some time of use the same problem happened. I am trying to find a solution. My thought is that this has to do with an SB or SI but not sure. The program seems ok with no compile errors. Waiting for help.
  2. Hello! I'm trying to configure CanOpen communication between Lenze ECSxP Posi&Shaft and Unitronics V1210. I want to set the velocity and the position using PDO1. If I give a high level to the fifteenth bit the control word becomes: First 15 bits are control bits (begin from 0) The velocity value is between 16 to 31 bits it means i can store the value using MI. The velocity is effected in the process data telegram in percent of maximum speed. And the position is between 32 to 61 bits. It is carried out in the process data telegram in resolver increments. I want to give values between 16 and 61 bits It is not possible to use MI to store the position value i need DW, however...inside CANopen Configuration block for RPDO Tx i can use only MI only ML or only DW. Could you give me suggestions how to solve the problem?
  3. Hi I have a question about ladder programming (in visilogic): MI1 is coming from a keypad entry, the value range is 0-100. MI2 is coming from an analog input, and is already scaled to the range 0-100. How can i force MI1 to #0 if MI2<20. The MI1 should not be changable by the keypad when MI2<20. Sorry for such a easy and maby silly question. -- IanM
  4. Hi everyone! Does anybody have experience with extracting numerical values from SCAN FB? Im communicating between controller and V350 over serial cable. And receive messages like: R+400<CR><LF> R-3000<CR><LF> Using <LF> as ETX. In the SCAN FB i have tried configuring this message in many different ways. But did not have succes. It alwas returns -1 in "Index of received message". Simple fixed length message without variables i can receive just fine. Any ideas? or pointers? Greets Tom
