Mode 5D (Only for Digital Transmission Paths)

When using digital interfaces exclusively, up to 16 independent command inputs can be transmitted transpar-
ently to the distant station with operating mode 5D and can be routed to commands outputs there. 4 Interface
Command Modules IFC-P/D (for Binary I/O) or one EN 100 interface (for GOOSE I/O) are necessary for this
application.
The default program setting is 1:1 transparent. That is BI1 = CO1, BI2 = CO2 ... BI16 = COC16
NOTE

In device configurations with EN100 and IFC (mixed mode) the first input ports are always allocated to the
pre-configured EN100 channels. The remaining input ports (depending on the number of assigned EN100
channels) are allocated to the input ports of IFC module in ascending order, IFC-1/IN1, IFC-2/IN2, etc.
