6th character: Master.This character defines the poll delay that prevents the OTIS
equipment from being overloaded. A lower value speeds up the integration. A higher
value slows down the integration. Any invalid character uses the default poll delay
of 400 ms. Slave: Not used
7th character: Mas
ter. This character defines the how many times a message is
retried before OTIS is declared offline. Any invalid character uses the default
number of 3 retries. Slave: Not used
8th character: Mas
ter & Slave. This character defines the priority of the OTIS
integration within a CK721-A controller. This setting should not be changed unless
after consultation with Technical Support. Any invalid character uses the default
priority of 19.
All subsequent charac
ters can be freely chosen.
Example 1:
“(9D5) Controller XYZ” defines a master panel that uses a 200
ms OTIS timeout, a
400 ms poll delay, and 3 retries. The OTIS integration uses groups 1, 3, 4, 5 and 8,
and the elevator with the most landings has between 33 and 40 landings. No change
to the priority was made.
Example 2:
“(9D5128) Controller XYZ” defines a master panel that uses
a 100 ms OTIS
timeout, a 200 ms poll delay, and 8 retries. The OTIS integration uses groups 1, 3, 4,
5 and 8, and the elevator with the most landings has between 33 and 40 landings. No
change to the priority was made. This OTIS integration runs faster than the one in
example 1, but it exceeds OTIS's recommendation for the maximum rate of polling.
