8.38 DR 48 date and time 2 (for Modbus)
The SIWAREX module has its own hardware clock. The current date and the time can be set
and read using data record DR 48. The clock is buffered with a capacitor and can continue
operating for up to approximately 70 hours without supply voltage. If you are not using the
Modbus protocol, data record DR 8 is used for the date and time because it has the
SIMATIC DTL format directly.
