7.3 Network, serial sending, FD-10 N

Send PROFIBUS in data from one FD-10 to an other FD-10 to be set as PROFIBUS out
data, on demand (event) by the PROFIBUS DP master in the sending PROFIBUS DP net.
One of the included FD-10’s can send I/O data to any other FD-10, selected by serial
transfer address. Note that the first data word, command output and one data word sta-
tus input has to be included in PROFIBUS I/O data of FD-10.

Arbitrary FD-10 can send a frame to an other FD-10 at any time.This serial addressing
enable access to up to 64 independent remote PROFIBUS DP nets by only one serial
transmission line (e.g. radio system or RS-485).To reduce collisions on the transmission
line, the frequency or time between events resulting in sending has to be limited.
The degree of limitation depend on the number of FD-10’s and data rate of the serial
transfer.

FD-10 can send frames when the unit is in normal operation mode and the PROFIBUS
DP is active, LED CONF inactive and BA active.

7.3.1.1 Expert configuration

Serial transfer > Expert parameters

Acknowledge timeout [ms]

Set the maximum allowed time from sending a serial
transfer frame until received acknowledge.
The status TO will be set high (1) when this time has
been exceeded without any received acknowledge.
Default is 500.

Max time between bytes in

Set the maximum allowed time between bytes in a serial

frame [ms]

frame. Default is 100. Useful when a frame will be divided
by transferring units which can cause a gap in parts of the
frame.
