  1. Hello, I have a very simple program running on a Samba. I have been asked to include some data capture with an SD card so I have bought some V350 to replace the samba's. Although the program is simple it is quite long. Is it possible to transfer the ladder logic from the Samba to the V350 without having to rewrite it? Thanks in advance for your replies!
  2. Hello, Unfortunately I can post code as its on a works laptop. I have a compare block that when the condition is met should go high. Problem is the set coil connected to the block doesn't switch on. The coil is not used anywhere else on the program. When doing a online test the compare box does go red when the condition is met, but the attached coil is unaffected. Anyone have ideas?
  3. Hello, I have a bipolar stepper motor and drive which I control with an arduino board. I stumbled upon PTO whilst looking through the help section of visilogic. I have a v350 tr and would like to try and use PTO to control the stepper. Is it possible to use PTO for this? the driver requires 4 inputs, do you have to find a driver that only needs one pulsed input? Thanks in advance
  4. Thanks Joe. The values are in the preset as you said. In order for the new preset value to take effect, does the PLC have to be restarted?
  5. Hello, I am trying to load a timer with a value entered from the HMI. As you can see I have linked the timer TD to an operand in the ladder. The problem is when you enter the time value from the HMI it doesn't load this value into the timer in the ladder. Could someone please help me work out how to do this. Thanks in advance
