This timer for 1s units works as an ON-delay timer. If the start contact of the function block is in the

ON state, the preset time SV (set value) is started. When this time has elapsed, the timer contact T

For the TM_1s_FB function block declare the following:

 The number of available timers is limited and depends on the settings in the system

registers 5 and 6.

 The system timer functions (TM_1s, TM_100ms, TM_10ms, and TM_1s) use the same

NUM* address area as the system timer function blocks (TM_1s_FB, TM_100ms_FB,

TM_10ms_FB, and TM_1s_FB). For the timer function blocks the compiler automatically

assigns a NUM* address to every timer instance. The addresses are assigned counting

downwards, starting at the highest possible address. In order to avoid errors (address

conflicts), these timer functions and function blocks should not be used together in a
