Indicator
A green LED (LED1) is provided to indicate when the Multicom interface has achieved the
DATA_EXCHANGE state with the Profibus network master. This serves as a convenient indicator that
the Profibus master and Multicom interface are configured properly and are exchanging data.
Profibus Network Connector
The network interface is a standard DB-9 female connector. The metallic housing of the DB-9
connector is typically connected to the network shield in the attached Profibus connector. The DB-9
housing can, in turn, then be connected to earth ground if desired.
Input/Output Data
The Multicom interface’s cyclic output (control) and input (status) data sizes are selectable (modular) in
16 different configurations representing sizes of between 4 and 40 bytes.
Via these data structures, any data item (command data, monitor data and configuration parameters)
available in the drive can be accessed. For detailed explanations of the format and usage of the
input/output data, refer to section 9.4.
