How to Use the Sequence Table Block Appendix B
Elements
The following operations can be performed after the element (timer/counter) is registered in Element Display
Mode.
• Enter as an operation in the actions section (as an output) of the table.
• Read the completion flag in the conditions section (as an input) of the table.
• Read the data such as the PV in the conditions section (in a relational expression) of the table.
Timers
The timer starts operating when the reset start signal goes ON.
The LO (pre-alarm occurring) signal will be turned ON when the elapsed time reaches the preset alarm value.
The HI (timer completion) signal will be turned ON when the elapsed time reaches the set value.
• Register the timer as an element. (Can be registered in Element Display Mode.)
Element number: 0 to 999 (Element numbers are shared with counters.)
Set value: 0 to 32,000
Pre-alarm value: 0 to 32,000
Timing unit: 1 to 4 (1: 0.01 s; 2: 0.1 s; 3: 1 s; 4: 1 min)
• Control bits (Can be specified as outputs in the actions section.)
RS: Reset start (Enter “Y” for timer start or “N” for timer stop.)
PS: Pause (Enter “Y” to pause timing or “N” to resume timing.)
• Status flags (Can be specified as inputs in the conditions section.)
HI: Timer completion
LO: Pre-alarm occurring
NR: Timing
IO: Stopped
PS: Paused
• Status data (Can be specified in relational expressions.)
PV: Present value (0 to 32,000)
DV: Remaining time (0 to 32,000)
Counters
The counter starts operating when the ST (Count start/stop) signal goes ON.
The LO (pre-alarm occurring) signal will be turned ON when the count reaches the preset alarm value. The HI
(counter completion) signal will be turned ON when the count reaches the set value.
• Register the counter as an element. (Can be registered in Element Display Mode.)
Element number: 0 to 999 (Element numbers are shared with timers.)
Set value: 0 to 32,000
Pre-alarm value: 0 to 32,000
• Control bits (Can be specified as outputs in the actions section.)
ST: Counter start/stop (Enter “Y” to start counter or “N” to reset counter.)
• Status flags (Can be specified as inputs in the conditions section.)
HI: Counter completion flag
LO: Pre-alarm occurring
NR: Counting
IO: Stopped
• Status data (Can be specified in relational expressions.)
PV: Present value (0 to 32,000)
DV: Count remaining (0 to 32,000)
Note Unlike timers, counters will continue counting even after the set value has been reached and the HI sig-
nal is turned ON.
