21 INDEPENDENT/LINKED OPERATION OF INTERFACE
21.2 Setting and Data Flow of Interlink Operation
21.2 Setting and Data Flow of Interlink Operation
During the interlink operation, all data received from either one of the two interfaces is transmitted to the other interface.
When two interfaces are in the interlink operation, the transmission time for one character becomes equal to
the H/W gate OFF time.
Setting
For the interlink operation of two interfaces on C24, configure the parameter setting as shown below.
Data flow in interlink operation
The two interfaces operate interconnectedly using the functions configured in "Communication protocol setting" from "Basic
Settings" "CH2 side" of module parameter (MC protocol (same format) or nonprocedural protocol) within the transmission
specifications set in the respective transmission settings.
