Better is to use an object in picture that has a 1 sec trigger. but for vbs, i have no better solution for sleep(). This also halts the vbs-skript-engine. dim oTag oTag = HMIRuntime.Tags("tag") oTag.Value = 0 oTag.Write,1

Only one suggestion can be from my side is delay from PLC. For example some script must run when I0.0 is "1". Then you do in program: [code] A I0.0 L S5T#1S SD T0 A T0 = M0.0 [/code] and run script on M0.0 trigger event. This would be safe and correct.
