Perspective Button onClick Action scripting

[Daniel.Snyder]

Momentary push buttons through HMIs are not recommended. This thread will lead to discussions about them:

HMI Momentary button Gets stuck with N/O Bit of PLC

[image] I have two dynamically tagged momentary button for each of this START and STOP bit. Some reason, most of the time, B10.0 get stuck and latched in PLC, this causes not able to shut the motor down. Its control value is assigned to its respective tag as bidirectional with 2.5 sec, but still it gets hung up. Any one experienced this type of problem or I am doing some thing wrong. ?

Or just all these threads (notice all the problems they tend to have):

However, if you have to, you could use system.tag.writeBlocking in a Button's onMouseDown and onMouseUp events. I would personally not do it this way.
