FEC AFC1500 - Manual (Page 26)

Interface Board Setup
The Multi Unit is able to operate under different Input/Output control
structures through use of a modular I/O interface board installed in the unit.
With the introduction of “Open” communication networks known as
“Fieldbus”, the direct interfacing to these networks became necessary. FEC
integrated many of these Fieldbus directly into our system through use of a
modular I/O board interfacing these networks directly to our I/O.
The available interfaces are: Discrete I/O control (24VDC Sinking), InterBus
S, DeviceNet, Profibus, Mitsubishi CCLink & Allen Bradley Remote I/O.
The fieldbus interface boards are integrated directly to internal I/O signals
which eliminate associated I/O wiring thus reducing overall assembly labor.
In fieldbus systems, the communication is typically of the Master/Slave format
in which the FEC unit is a slave to the master CPU.
All I/O Motherboards have a DIP Switch SW1 (located at position 7D) which
has to be configured so the Multi Unit can identify the type of interface
installed.
To install an interface board:
1 Set the DIP Switch SW1 according to the table shown below.
2 Open the Multi Unit and mount the interface board.
3 Connect the ribbon cable from the Multi board CN2 to the interface board CN1.
4 Assemble the Multi Unit.
