010 to 020 for the step ladder block to which
the timer is associated can be used for timeout
detection. The present timer values can be
confirmed by confirming operation of the step
ladder. The present value and set value are
displayed under the TIM command in the Vali-
date Action Window.
STEP Timer setting This is the timer (setting range: 0 to 9999 sec)
TIMER value for moving between steps. It has no input
conditions.
(STEP TIMER is placed in the same line as the
STEP command.)
Operation is started when program execution
moves to the line containing the STEP com-
mand.
When the time set by STEP TIMER is reached,
the program execution moves to the next step.
Note: "Input condition commands" are given top
priority.
ALARM Timer setting This is the timer (setting range: 0 to 9999 sec)
TIMER value for monitoring steps. It has no input conditions.
(ALARM TIMER is placed in the same line as
the STEP command.)
Operation is started when program execution
moves to the line containing the STEP com-
mand.
When the time set by ALARM TIMER is
reached, the Step Timer Completion flag (step
congestion indicator) turns 1 (ON).
At this time, the step is held at the current val-
ues.
ED Indicates the end of a program.
Note: The END instruction is automatically
placed at the end of program when the Step
Ladder Program block is prepared using CX-
Process Tool. It is placed after STEP00 when
the program comprises STEP00 only, and is
placed after the nth STEP where the program
ends.
Note The TIM command can be used with LCBVV projects of Ver. 3.0 or later. Refer to
the Loop Control Board Operation Manual (Cat. No. W406) for details on the TIM
