ASD-to-ASD Communications (RS485 2-wire)
Program Communications Communication Settings
The function of this parameter is 2-fold:
1) In a Master/Follower configuration and while communicating via RS485
2-wire, this parameter sets the ASD as the Master or the Follower.
2) This parameter determines the function of the ASD while operating as the
Master or the Follower. If operating as the Master ASD, an output parameter
of the Master ASD is used to control the Follower ASDs and is set here.
If operating as a Follower ASD, the ASD response if an error is incurred is set
here.
Note: Select a Follower function here if F826 is configured as a Master
Output controller for any other ASD in the system. Otherwise, an
EOI failure will result.
Changes made to this parameter require that the power be cycled (off then on)
for the changes to take effect.
