Hello,

In S1200 I can add such timers - TP , TON , TOF , TONR. When I add S1500 to project I can add additional timers such as S_ODT or timer based on coils such as SS etc. In 1200 I cant find such and there is no data type such as TIMER - Is this because of CPU version ? ( those timers are only available in 1500 ) , firmware version or I need to install some packages?

Please check below link.
