Micom P634 - Assigning Communications Interfaces to Physical Communications Channels

3.12.15.1 Resetting Actions through Keys on the Local Control Panel
Further resetting possibilities are basically not distinct resetting actions but make
access especially easy to one of the resetting actions described above i.e. by
configuring them to a configurable key.
●
One can include the relevant resetting action in the configuration of the
“READ” ( ) key (through LOC: Fct. read key).

Fig. 3-67: Assignment of communication interfaces to physical communication channels.
Depending on the design version of the communications module A there are up
to two communications channels available (see “Technical Data”, Chapter 2,
(p. 2-1)). These physical communications channels may be assigned to
communications interfaces COMM1 and COMM2.
If communications interface COMM1 is assigned to communications channel 2,
then the settings of communications interface COMM2 are automatically
assigned to communications channel 1.
COMM2 can only be used to transmit data to and from the P634 if its PC interface
has been de-activated. As soon as the PC interface is used to transmit data,
COMM2 becomes “dead”. It will only be enabled again when the “time-out”
period for the PC interface has elapsed.
