To Compute the TempScan/1100 Scan Interval
To compute the time interval for the TempScan/1100 to acquire one scan, use the following formulas:
• For a 60 Hz line cycle: Scan Interval is:
Is-t = [Next highest integer (Dv / 4)] x R1
• For a 50 Hz line cycle: Scan Interval is:
Is-t = [Next highest integer (Dv / 4)] x R2
Where:
Is-t = Scan Interval for the TempScan/1100, milliseconds.
Dv = Disposition, variable number of non-empty 4-channel blocks.
R1 = Sampling Rate, constant of 16.67 milliseconds (per 16-channel block) for a 60-Hz line cycle.
R2 = Sampling Rate, constant of 20.00 milliseconds (per 16-channel block) for a 50-Hz line cycle.
For example, if the nine (9) channels 1, 2, 3, 4, 5, 7, 15, 100, and 101 are configured, then there are five (5)
non-empty 4-channel blocks (refer to the table on disposition). Using the scan interval formula for a
TempScan/1100 system with a 60-Hz line cycle, gives:
Is-t = Next highest integer (5 / 4) x 16.67 millisec.
Is-t = 2 x 16.67 millisec = 33.33 millisec.
However, if nine (9) channels are configured less densely by every fourth channel from channel 4 through
36, then there are nine (9) non-empty 4-channel blocks. Using the same formula gives:
Is-t = Next highest integer (9 / 4) x 16.67 millisec.
Is-t = 3 x 16.67 millisec = 50.00 millisec.
Clearly, despite the identical number of configured channels, the disposition affects the TempScan/1100
scan interval. Meanwhile, the following table shows how the fast mode scan rate varies when the number
of configured channels increases where these TempScan/1100 channels are all adjacent to each other.

(1) The number of selected channels refer to configured channels which are all adjacent to
each other. (2) These values were obtained from the above TempScan/1100 scan interval
equations.
