If Dip-Switch 2 contacts are opened, the baud rate is selected on parameter 112
bd.rt.
(
“Baud Rate”
word 2112).
Module
can introduce a delay (in milliseconds) of the response to the master
request. This delay must be set on parameter 114
se.de.
(
“Serial Delay”
word 2114).
Each parameter modification is saved by the controller in the EEPROM memory
(100000 writing cycles), while the setpoints are saved with a delay of 10 seconds
after the last modification.
NB : Changes made to words that are different from those reported in the following
table can lead to malfunction.
