6.7.7 Telemetry Auto-scan Data Interval
The telemetry auto-scan data feature provides logging data at fixed intervals. It is a timed event that operates very
much like a date/time trigger event but it is a very specialized case. First, it is not programmed in the same area of
memory as the other date/time triggers. Second, it has a fixed set of timing options. And third, it has a fixed function
and that is to send data readings to an external device.
The programming options for this feature are easy. Find the number of relay panels that are installed in the system in
the table below and program V1 from the table at address 1012 in the programming address table.
V1
Number of relay panels installed
0*
Feature disabled
1
1 relay panel—8 telemetry channels maximum
2
2 relay panels—16 telemetry channels maximum
3
3 relay panels—24 telemetry channels maximum
4
4 relay panels—32 telemetry channels maximum
5
5 relay panels—40 telemetry channels maximum
6
6 relay panels—48 telemetry channels maximum
7
7 relay panels—56 telemetry channels maximum
8
8 relay panels—64 telemetry channels maximum
* This is the default setting.
The timing interval, the time between sets of telemetry readings, is calculated automatically. It is a function of the
number of telemetry channels available. The interval will be between 1 and 4 minutes.
The function performs a telemetry auto-scan in data mode. The scan starts with channel 00 and ends with the user-
adjustable auto-scan stop channel.
6.7.8 Telemetry Auto-scan Stop Channel
The auto-scan stop channel, mentioned above, tells the RFC-1 at what channel to stop during an automatic logging
sequence. The auto-scan stop channel is located at memory addresses 1010-1011.
Set the stop channel by programming the first digit of the stop channel at memory location 1010 and the second digit
at memory location 1011. Program a zero at address 1010 if the channel number is less than 10, such as 01, 02, 03,
etc. Valid channel numbers for the stop channel are 01-63.
