  1. Ok . . . What is it exactly you are asking? In the last post chrobakpeter mentioned he needed to add a powered loop converter to get these Samson devices to work. Joe T.
  2. You're asking for a common self-resetting alarm acknowledge circuit. Use a separate coil for the actual alarm output- Joe T.
  3. Cam and I obviously did not maintain proper social distancing on replying to this post. 😁 Joe T.
  4. 1. There are multiple locations on the -E3XB module to connect power. Verify you have power connected to V1 and 0V. 2. Most of the outputs on this module are relays. Are you saying you have no voltage on them or on O0 and O1? Are the relays on the other outputs clicking? Joe T.
  5. This is exactly what happens and the biggest mistake beginners make. They assume that if the subroutine isn't being called anymore that any coils and/or timers in that subroutine get reset. They do NOT. They are left in whatever state they were in the last time the subroutine is called. Every one of my programs contains a subroutine called "Outputs", which is called continuously. All my outputs are listed in numerical order which makes them easy to find. Code for each output from other parts of the program comes together here - for example: Also, if you're new, stay away from Display controlled subroutines. Unless you've got a whole bunch of things that have to happen specific to a display, use the "Display Active" bit along with rising an falling edge transitional contacts is an always-called subroutine called "Display Controls" (also one I always have). Separate the logic for each display with network comments. The point of all this is the more subroutines you have, the more confusing your code will be, even to you. Try thinking about looking at this code six months from now and remembering what you did. Joe T.
  6. He's talking about getting Modbus TCP library that you can include and call from your code. Google is your friend- https://sourceforge.net/projects/easymodbustcp/#focus Joe T.
  7. When I've done servo control utilizing Modbus there's usually an external I/O board available for the servo that allows starting and stopping via discreet inputs to the servo itself. I use the Modbus portion to set parameters in the servo before I trigger a move with a voltage signal or contact. Modbus via RS485 is nowhere near fast enough or reliable enough. Joe T.
  8. This post was started for a V120, which has limited features. What family of PLC are you working with? Joe T.
  9. Good morning everyone. I have an OPLC V1040, to which, I would like to connect a mouse, however, I have not found how to carry out this activity. Could you help me to make such a connection if this is possible or answer me that it is not possible. Thank you. Unfortunately, that's not something you can do in a V1040. Joe T.
  10. It's very easy with the Schedule function block. I've attached the program from the UniLogic Example Projects collection, which is on the download page. I recommend everyone who plays with UniLogic download this as a reference. Joe T. UniStream_070_schedule.ulpr
  11. There could be a number of problems with your PLC program if you haven't done Modbus before. For example, you have a timer with a 0.1 second preset in your screenshot. To me, it looks like you are pinging the servo at 0.1 second intervals, which is too fast for RS485 Modbus. Please attach your .vlp file to a forum post so we can get a better idea of what you're doing. Joe T.
  12. Depending on EXACTLY what math you want to do, the old Visilogic Linearize Array would do it. I ran into this trying to convert a Visilogic program to UniLogic. The following post addressed this problem, including an attached UDFB: http://forum.unitronics.com/topic/6080-adventures-in-unistream-conversion-vect-linear/?tab=comments#comment-24545 Joe T.
  13. If you have trouble with the font handler post your program and let us know specifically the font name and the special character code you want to include in your text. Joe T.
  14. I've done a project using a Delta servo and a Vision. The entire controller is manipulated via a Modbus table. To that end, the first thing you have to do is establish first contact with the servo via RS485. Try to read the firmware version from the drive at holding register 0. It is a single 16 bit register. Also - post your PLC program here so we can have a look at your communication routines and also post a schematic of exactly how the Samba is connected to the servo system. Joe T.
  15. The SD card must be formatted FAT32, which limits the card size to 32 GB. I don't know why it let you try anything else. Joe T.
