4.2.3 Scan Time

The processing time from a 0 step to the next 0 step is called scan time.

1) Expression for scan time

Scan time is the addition value of the processing time of scan program that the user has written, of the task program

processing time and the PLC internal processing time.

(1) Scan time = Scan program processing time + Task program processing time + PLC internal processing time

•

Scan program processing time = The processing time used to process a user program that is not specified to a task program.

•

Task program processing time = Total of the processing times of task programs executed during one scan.

•

PLC internal processing time = Self-diagnosis time + I/O refresh time + Internal data processing time + Communications

service processing time

(2) Scan time differs in accordance with the execution or non-execution of task programs and communications processing, etc.

2) Flag

(1) Scan time is stored in the following system flag area.

•

_SCAN_MAX : Maximum scan time (unit : 1 ms)

•

_SCAN_MIN : Minimum scan time (unit : 1 ms)

•

_SCAN_CUR : Current scan time (unit : 1 ms)

4.2.4 Scan Watchdog Timer

1) Watchdog timer is used to detect a delay of abnormal operation of sequence program.

(Watchdog time is set in menu of basic parameter of GMWIN.)

2) When watchdog timer detects an exceeding of preset watchdog time, the operation of PLC is stopped

Immediately and all output is off.

3) If an exceeding of preset watchdog time is expected in sequence program, use ‘WDT_RST’ function.

‘WDT_RST’ function make elapsed watchdog time as zero.

4) In order to clear watchdog error, using manual reset switch, restarting the PLC and mode change to STOP
mode are available.

REMARK

Setting range of watchdog : 1 ~ 65,535ms( 1ms base )
