Hello! I use VisiLogic v.9.8.9 for programming PLC V570. I want protection my project for impossibility from upload, but I can't. In download properties menu this parametr isn't active (attach file - screenshot_1). How I can do it? Thanks!
We are looking at mounting the V350 outside and need the extra protection of a clear cover/ access door BUT it must be a tight fit due to space restrictions and allow access to the touch screen. Omron have a cover that is ideal for a standard temperature controller but not the shape of the V350 (it’s not square). Any suggestions would be appreciated.
I have a M91-2-R1 to control 2 heatgun and 2 exair cooling vortex tube. I use 120Vac scr to start the heatgun and 120Vac solénoïde valve for the cooling. Do I need a RC supressor or other protection for the contact of the plc? The cycle is 1. turn ON heater 7 sec. turn OFF heater and start cooling 7 sec. turn OFF cooling 2. turn ON heater 7 sec. turn OFF heater and start cooling 7 sec. turn OFF cooling 3. turn ON heater 30 sec. turn OFF heater We make this cycle 7 hours per day. Now I have a one bad contact relay. The M91-2-R1 is the best to control scr and solenoide valve? I chose this plc because I have a department that use 52 of this plc. Thanks!
