Clock Functions
The clock function has a date (Western calendar.) Time is not backed up when the
power supply is shut off. Clock accuracy is ±5 ppm.
Time on the VZ20X is not backed up. Set the date and time of the PC/PLC via
Modbus/TCP. If the date and time are not set from the PC/PLC, the date and time start
from 1970-01-01 00:00:00.000.
At writing of the time, the time stamp is omitted or set in duplicate.
In a daisy chain connection, set the date and time to the master unit of the daisy chain
VZ20X from the PC/PLC.
In the case of a GA10, the date and time are set automatically.
Leap seconds are not compensated for when time is are not periodically acquired from
the PC/PLC. Leap years are compensated for.
The date format is YYYY-MM-DD hh:mm:ss.nnn.
