Connected Posted February 4, 2017 Report Share Posted February 4, 2017 I am upgrading an old S7-200 plc to a Unitronics V130-33-TA24. In the old MicroWIN code they used contacts of a built-in half-second timer SM0.5. What would be the simplest way to recreate this in Visilogic? Would it require using 2 timers? I am attaching what I came up with and it works fine, but maybe there is a simpler way. Thanks. Quote Link to comment Share on other sites More sharing options...
MVP 2022 Joe Tauser Posted February 5, 2017 MVP 2022 Report Share Posted February 5, 2017 That particular time is built in to Visilogic. Use a contact referencing SB3. It is on for .5 second and off for .5 second. Otherwise, you do need two timers. Here is a 1 second on / 1 second off example: Timers automatically reset when you remove power from them. Note that proper programming form is to use the timer bit in a separate network from the timer coil. The reason for this is Visilogic doesn't always compile the network they way you think it does.
