Energ ySmart Dr yer System Modbus
Communications
(continued)
One message is polled every 2/10 of a second. It takes 2.2 seconds to obtain data
from all EnergySmart Dryer system components. If a component fails to respond
nine (9) times when polled, it is removed from the poll list. The communication fail-
ure is indicated with an alarm message on the operator interface terminal. The com-
ponent that failed is put back into the poll list when the “Alarm Acknowledge” button
is pressed on the Alarm Log Screen (Screen 14), or after 300 seconds by the
Communications (Comms) Retry Timer.
Each individual message command can be disabled by a Supervisor on the Read Data
Communication screen (Screen 35).
This could be necessary if there is a failure of the communications hardware on a par-
ticular component. When communications is operating properly, the error count num-
ber will not increase. When one component has a communications problem it affects
the whole network. You will see the error count numbers start to increase when this
occurs.
