date: 2024/9/24
The time and date is not displayed correctly.
The solutions vary depending on the screen data settings.
Check the following settings.
Setting location:
V-SFT editor [System Setting] → [Unit Setting] → [SRAM/Clock] → [Use SRAM Calendar]
Checked ..... Clock built in the V series used
Unchecked ..... Clock built in the PLC used
[[Use SRAM Calendar] checked]
<Causes>
- No battery is set in MONITOUCH.
- The battery is flat.
- The clock built in the V series is not set to the correct date and time.
<Solutions>
- Check that a battery is set in the battery holder on the backside of V series.
- If the battery is flat, the message "Replace the battery" is displayed at the lower right of the screen in Local mode. Replace the battery with a new one.
- There are two methods for adjusting the clock of the V series. Follow the steps below.
- Method 1: Adjusting in Local mode
There are two methods for adjusting the clock of the V series. - Method 2: Adjustment using a macro command
It is necessary to create a clock correction screen.
Macro command to use: "SET_SYS_CLND"
For more information on macro commands, refer to the V10/V9/X1 Series Macro Reference Manual.
[[Use SRAM Calendar] unchecked]
The clock built in the PLC is used.
<Causes>
- No battery is set in the PLC.
- The clock built in the PLC is not set to the correct date and time.
<Solutions>
- Set batteries in the PLC.
- There are two methods for setting the date and time.
- Method 1: Correct using the PLC programming tool and [Calendar Read Device]
The PLC calendar memory can be corrected using the PLC programming tool.(For correction on the PLC, refer to the relevant PLC manual.)
Calendar data is read into the V series at the leading edge (0 -> 1) of the [Calendar Read Device]*.
* Set the [Calendar Read Device] using V-SFT-6.
[Setting location]
[System Setting] -> [Hardware Setting] -> [Control Area] -> [Calendar Read Device] - Method 2: Adjustment using a macro command
The PLC calendar can be corrected using macro command "SET_CLND".
Example: To correct 4/1/2014 10:40:00 to 4/20/2014 12:00:00
(1) Create a calendar setting screen.
Place the following parts on the screen.
・Keypad
・Numerical data display part
[Function:Entry Target] ($u0 to $u5)
・Switch ON macro "SET_CLND"
・Time display or calendar
(2) Input year, month, day, time, hour, minute, second in order using the keypad, and press the switch to execute the SET_CLND macro. The PLC calendar is rewritten.
Set 4/20/2014 12:00:00.
Year: $u0 = 2014
Month: $u1 = 4
Day: $u2 = 20
Hour: $u3 = 12
Minute: $u4 = 0
Second: $u5 = 0
The PLC calendar is read into the V series and the V series calendar is also re-written.
* The following macro commands are used to correct the calendar data in PLC2 to PLC8.
・PLC_CLND ... PLC calendar write
・SET_SYS_CLND ... V series calendar write
For more information, refer to the V9 Series Macro Reference Manual.
