DR 8 date and time
The weighing module has its own hardware clock. The current date and time are specified by
or read from data record DR 8. The clock is buffered with a capacitor and can continue
operating for up to approximately 70 hours without supply voltage.
If you are using the Modbus protocol, data record DR 48 must be used for the date and time
because the SIMATIC DTL format is not supported by Modbus.
