Time DB Offset
-1 or 0 to 3994
This parameter sets the location in the database where the gateway’s current
date and time will be copied to.
Note: The following tables lists the 12-byte data area placed in the database if the Time DB Offset
parameter is set to a value other than -1:

Command Delay Timer
1000 to 60000 milliseconds
This value is used for time-tag validity verification for the ASDUs listed
below. The received commands will only be accepted if [timestamp + Command
Delay Timer] is greater than the gateway's own time.
58: Single command with time tag CP56Time 2a
59: Double command with time tag CP56Time 2a
60: Regulating step command with time tag CP56Time 2a
61: SetPoint command, normalized value with time tag CP56Time 2a
62: SetPoint command, scaled value with time tag CP56Time 2a
63: SetPoint command, short floating point with time tag CP56Time 2a
107: Test command with time tag CP56Time2a
If the value is less than 1000 milliseconds, the gateway will default to 5000
milliseconds
Maximum ASDU Resp Len
25 to 246
This parameter limits the maximum size of the ASDU portion of a response
message. Most applications will use a value of 246.
