Hello ,

I want to compare 2 variable with TIME type in s7 300 but i think there is no any function like SUB,GT,LT or like these Functions for time, can anyone help me or has an idea what should i do ?

 TIME is similar to a  DINT that has 32- bit data length and keep the number of milliseconds in a time value. You can compare 2 time values by DINT compare instructions. 

I hope it helps,

i have done it , but when i want to use simulator it doesn't work 

 Sorry , I can not help you without a snapshot of your actual test.It will work , if you write your program correctly .

you need use MOVE to move the time to a temporary dint variable then compare it

OR do comparison in STL

L Time1

LTime 2

>=D

= Mx.y

gives Mx.y=1 when Time1>=Time2
