When only the Holiday option is selected in the Week/Holiday condition, it means this schedule will trigger only on holidays.
Example: Whenever there is a holiday, the traffic signal will start flashing at midnight 00:01 and end at 23:59 of the same day.
In the Week/Holiday condition, selecting only Monday to Sunday without selecting holidays means that this schedule will trigger only on weekdays.
Example: On weekdays (non-holidays), turn on the lobby lights at 8:00 in the morning and turn them off at 5:00 in the afternoon.
In the Week/Holiday condition, selecting both Monday to Sunday and holidays means that this schedule will trigger on specified weekdays or holidays.
Example: Whenever it's Wednesday or a holiday, turn on the driveway lights at 6:00 in the evening and turn them off at 10:00 at night.
Conditions:
1. At the entrance of the driveway, when the infrared sensor X0 is triggered, it activates the opposite exit signal light Y0.
2. The signal light operates in a cycle of ON for 0.3 seconds > OFF for 0.3 seconds > ON for 0.3 seconds > OFF for 0.3 seconds, and so on.
3. At the end of the driveway entrance, there's another set of infrared sensors (X1). The signal light Y0 stops outputting only after a vehicle triggers X1 and leaves.
4. The above operation sequence is triggered only on holidays, defined here as Fridays, Saturdays, and Sundays (excluding public holidays).
5. For holiday settings. You can manually select holidays in the [Holiday] section or edit and download them in 701ClientSQL.

Pulse Output / Toggle
Conditions:
On-site, there is a light signal device that needs the PLC to provide an output for 10 seconds every minute.
Instruction Explanation:
※Since TMR 000 continuously cycles between 0 and 60 seconds, each time TMR000 = 0, it will execute a Pulse output. This setup meets the requirement of providing a 10-second output every minute.
This configuration is suitable for short cycle outputs, directly specifying on-site cycles of every n seconds/minutes; for outputs required every hour or longer, refer to A-3 for hourly timed triggers.
Condition:
There is a traffic signal on-site, and after triggering, the green light stays on for 20 seconds. After the green light, the yellow light stays on for 5 seconds, and after the yellow light, the red light stays on for 20 seconds.
Instruction Explanation:
This example uses the Pulse function to control time, and conditions like the previous output OFF combined with the next output ON to trigger the next actual output. This example can be extended continuously until all 64 schedules are used up.

C. Advanced Application Scenarios
Trigger the Alarm When Door Open more than 10 minutes
Condition:
The main door is equipped with door sensor, serving as the condition for starting the Timer. When the main door is open (door sensor short-circuited) for more than 10 minutes, it will trigger an alarm. The alarm will persist until the main door is closed or until the administrator presses the release button.
Instruction Explanation:
Referenced Commands:
Timer / Counter / Virtual Output / Self-holding
For this example, we have eight infrared devices with edge-triggered Inputs 0-7, and we want to activate corresponding Outputs 0-7 for alarm indicators. Additionally, the manager requires the on-site personnel to have manual control over whether the corresponding alarm indicators should be activated after each infrared device trigger.
Answer: Set the output mode of 0-7 point to ON. When the condition is met for triggering, activate the output alarm indicator. The condition content is edge-triggered (^.Di), and the virtual point Y8 (&Do) must be in “on” state simultaneously to trigger the corresponding alarm indicator.
The virtual output M8-15 can be triggered through 701Client graphical control or developed using third-party software with Modbus triggering.
Application Architecture :
Sequentially triggers Y0~Y6 to create a running lights effect. The activation time is from 13:01 daily to 12:59 the next day, and it stops operating from 12:00 to 13:00 at noon.

4 Doors Interlock: When one of the doors is unlocked, other 3 doors could not be unlocked until that door is closed
Instruction Explanation:
1. When the door sensor DIX3 / DX5 / DIX7 and the door lock relay DOY2 / DOY4 / DOY6 of door B/door C/door D are closed, press Door A push button DIX0 , the door lock relay DOY0 can be trigger on 6 seconds.
2. When the fire alarm input DIX16 is closed, the door lock relay of door A/door B/door C/ door D can be released on;
3. When the door sensor DIX1 of door A is closed, the door lock relay of door A can be automatically relocked;
4. When the door sensor DIX1 of door A is forced to open and the door relay DOY0 of door A is off, the alarm relay DOY1 of door A will be turned on;
5. When the door sensor DIX1 of door A is open, the timer TMR0 is triggered. When TMR0 is more than 8 seconds, the door open too long alarm relay DOY1 is triggered.
6. When the door sensor DIX1 of door A is closed, the alarm relay DOY1 can be stopped.
※Pipe output (Applicable to firmware version 5.06 and above, released on December 22, 2023)
Starting from this version, Pipe Output is supported. When the virtual output 255 is ON (as fixed conditions), it will trigger Pipe Output. This means that within the same time,
Pipe outputs will not do the output simultaneously; instead, they will be queued and executed in the order of triggering.
※The schedule for selecting Pipe output will not be executed when the virtual output 255 is OFF.
Condition Requirements:
There are three entrances to the parking lot, and each parking space is equipped with occupancy detection. When the parking system detects that the number of parking spaces is full, it will provide a signal to the 0808 PLC as a input to switch the barrier gate activation mode.
Instruction Explanation:
Referenced Commands :
Pipe Output / Edge Trigger
Conditions:
There are two sets of motor devices on-site (Motor A/Motor B). Each day at noon (12:00), one set of motor is triggered for one hour. Motor A is the primary motor, and it operates when the counter of Motor A is less than or equal to the usage count of Motor B. Motor B is the secondary motor and operates when the counter of Motor B is less than the usage count of Motor A.
Instruction Explanation:
Referenced Commands:
Edge Trigger (Rising) / Counter / CNT Comparison / Action Time
Conditions:
This method can generate a timer of any custom duration. In this example, a TIMER paired with a Counter creates a 24-hour cycle timer, which then triggers outputs at specific times. Following this logic, it can measure seconds, minutes, hours, days, months, years, etc., and specify conditions for triggering specific devices after a certain period.
A practical example: Patrolling point alarm output. Security personnel must swipe their security card at the site every hour. If there is no card swipe for over an hour, an alarm will be triggered at the security booth. If there is no card swipe for over three hours, an alarm will be triggered at the management center. This setup achieves different conditional alarms at multiple locations for different durations.
