Why does the TOD Clock in my Quantum 140ESI06210 ASCII Module go back to the default when I cycle power?

The Quantum 140ESI06210 ASCII Module does not have a battery to maintain the TOD Clock due to a power failure. A customer can either purchase a 140XCP90000 Battery Backup Module to maintain the TOD Clock due to a power failure or use Command 6 - SET TOD (Time of Day) from the Quantum PLC to set the TOD Clock of the 140ESI06210 using the Quantum PLC TOD Clock on a power failure.
Information on how to program Command 6 - SET TOD (Time of Day), is in the Quantum Automation Series 140ESI06210 ASCII Interface Module User Guide (840USE10800).
