2.9 Outline of I/O Assignment with PROFIBUS-DP

By installing the PROFIBUS-DP unit FCU8-EX563 and connecting the slave stations compatible with PROFIBUS-DP

communication to M8V Series expansion slot, NC can input/output the devices to/from the slave stations as the master station

for PROFIBUS-DP communication. However, it is not possible to use the NC with two units of FCU8-EX563 installed at a

time. If two units of FCU8-EX563 are installed at a time, both units stop their operation and the error occurs.

Hilscher's Fieldbus communication control unit (COM module) is mounted on FCU8-EX563, and parameters are set using

Hilscher configurator "SYCON.net". Up to 125 slave stations can be connected.

Inputs/outputs of the devices from NC's PLC are all handled as bit device data. Up to 512 points can be input/output.

Maximum number of inputs/outputs for NC remote I/O unit is 768, whether or not FCU8-EX563 is installed.
