retry for Repeater Set #2 will occur at the end of the queue, after an attempt has been made to
communicate with all sites using Repeater Set #1. The CCU will again wait the indicated number
of seconds for a reply. If no reply is received again, and if the # Tries field on the Status of Base
Unit window is greater than 1, the CCU will try again to communicate with the RTU, using the
same repeaters from RTU Repeater Set #2. The CCU will attempt to communicate with this RTU
with the repeaters from RTU Repeater Set #2 as many times as the # Tries fields indicates.
Note: To first try without repeaters (direct path) put the destination site address as the first
repeater in Set #1. The CCU will attempt to communicate using Set #2 only if the direct path
fails. To retry without repeaters (direct path) for Repeater Set #2, put the destination site address
as the first repeater in Set #2. If Repeater Set #2 is blank, no retries, direct or otherwise, will
occur.
If all attempts to communicate with the RTU fail, the CCU will generate a Comm Fail alarm
message for the Alarm Log, with the CCUs date and time of when the last failure occurred.
RTU Repeater Set #1
The format of these four data entry fields is from 0 to 3 digits each. If any repeaters are used, the
first repeater must be entered in the repeater box labeled 1-, with the second repeater in the box
labeled 2-, etc. If any repeaters are used, the RTU numbers must be entered as 3 digits each,
with leading zeros required. If a repeater is to be removed from use, replace the RTU number
with 3 blanks. To change any one of the repeaters, highlight the current repeater, then enter a
new 3 digit RTU number or 3 blanks.
These data entry fields control which RTUs are used as a first set of repeaters to reach this RTU.
Each of the four fields can contain one RTU number. RTU numbers must be entered in exactly
the same order as they will be physically used; entry 1 would contain the RTU number of the first
RTU in the link, while entry 2 would contain the RTU number of the next RTU in the link, etc.
If it is desired to first try the direct path and retry using repeaters only if the direct path fails, put
the destination site address as the first repeater in Repeater Set #1.
RTU Repeater Set #2
These data entry fields control which RTUs are used as a second set of repeaters to reach this
RTU if all communication attempts using Repeater Set #1 fail.
The format of these data entry fields is the same as for RTU Repeater Set #1.
If Repeater Set #2 is blank, no retries will occur if Repeater Set #1 fails; however, if it is desired to
retry a direct path if Repeater Set #1 fails, put the destination site address as the first repeater in
Repeater Site #2.
