1In the following example, 000500 would be turned ON 5.0 seconds after

000000 goes ON and then turned OFF 3.0 seconds after 000000 goes OFF. It is

necessary to use both 000500 and 000000 to determine the execution condition

for T0002; 000000 in a normally closed condition is necessary to reset T0002

when 000000 goes ON and 000500 is necessary to activate T0002 (when

000000 is OFF).

The length of time that a bit is kept ON or OFF can be controlled by combining

TIM with OUT or OUT NOT. The following diagram demonstrates how this is

possible. In this example, 000204 would remain ON for 1.5 seconds after

000000 goes ON regardless of the time 000000 stays ON. This is achieved by

using 001000 as a self-maintaining bit activated by 000000 and turning ON

000204 through it. When T0001 comes ON (i.e., when the SV of T0001 has ex-

pired), 000204 will be turned OFF through T0001 (i.e., T0001 will turn ON which,

as a normally closed condition, creates an OFF execution condition for OUT
