2The drive is a follower on the master/follower (DDCS) link.DDCS follower
3The drive is the master on the master/follower (D2D) link.
Note: This setting is only to be used with D2D
communication implemented by application programming.
If you are using the master/follower functionality (see page
34) through the XD2D connector, select DDCS master
instead.

4The drive is a follower on the master/follower (D2D) link.
Note: This setting is only to be used with D2D
communication implemented by application programming.
If you are using the master/follower functionality (see page
34) through the XD2D connector, select DDCS follower
instead.

5The role of the drive on the master/follower (DDCS) link is
defined by parameters 60.15 Force master and 60.16 Force
follower.

6The role of the drive on the master/follower (D2D) link is
defined by parameters 60.15 Force master and 60.16 Force
follower.
Note: This setting is only to be used with D2D

Ring / uint16Selects the topology of the master/follower link.
Note: Use the setting Star if using the master/follower
functionality (see page 34) through the XD2D connector
(as opposed to a fiber optic link).
M/F HW connection60.5
0The devices are connected in a ring topology. Forwarding
of messages is enabled.
Ring
1The devices are connected in a star topology (for example,
through a branching unit). Forwarding of messages is
disabled.
Star
10 / uint16Defines the light intensity of the transmission LED of RDCO
module channel CH2. (This parameter is effective only
when parameter 60.1 M/F communication port is set to
RDCO CH 2. FDCO modules have a hardware transmitter
current selector.)
In general, use higher values with longer fiber optic cables.
The maximum setting is applicable to the maximum length
of the fiber optic link. See Master/follower
functionality (page 34).
