IS the Estop activated from an outside input?
IF yes then you need to monitor that input and do a function IF it is active.
First you need to install a Label on your screen. Then set the label text to TICKER250 this will create a ticker label that you can send text to.
Next from the macropump you would add code to monitor the input and IF it goes active then send text to the ticker label
IF Isactive(input1) then
SetTicker(250," Estop is now active")
Else
SetTicker(250,"")
end if
As long as the input1 is active the message will flash and scroll across the label.
Hope that helps, If not tell us what you need
