7.1 Buffered, FD-40 B
Functions that are included in the FD-40 B:
1. Send some bytes of data direct to the serial interface
Send up to 6 byte data from PROFIBUS DP to the serial interface
2. Send data to buffer and finally send buffered data to the serial interface
once
Send up to 6 byte PROFIBUS DP data in time to the send buffer. By command can
these buffered data be sent to the serial interface. Up to 15 kbyte can be sent once.
3. Receive buffered data, from serial interface received data
Data received from serial interface will automatically be stored in the receive buffer.
These data will be picked up by PROFIBUS DP, 6 byte each time.
All these three functions are ready to use without any modification by the
configuration tool.
FD-40 can convert PROFIBUS DP data over the serial interface when the unit is in
normal operation mode and the PROFIBUS DP is active, LED CONF inactive and
BA active.
