7.2 Addressed, serial transfer master, FD-10 A
Transfer defined PROFIBUS I/O data modules between two FD-10’s, each time on
demand by a PROFIBUS DP master. FD-10 A is the serial transfer master that transfer
I/O data between various FD-10’s, selected by serial transfer address.This serial address-
ing enable access to up to 255 independent remote PROFIBUS DP nets by only one
serial transmission line (e.g. radio system or RS-485).
By FD-Tool defined PROFIBUS I/O modules will be mirrored between FD-10 A and the
serial addressed FD-10 P at the other side. Input modules of FD-10 will be sent to out-
put modules of FD-10 at the other side, and vice versa. Note that one data word com-
mand output and one data word status input has to be included in PROFIBUS I/O data
of FD-10 A.The command control the serial transfer and the status return information
about the transfer.
FD-10 can transfer frames when the unit is in normal operation mode and the
PROFIBUS DP is active, LED CONF inactive and BA active.

Select the desired parameters of the Serial interface.
PROFIBUS-DP > PROFIBUS DP parameters
PROFIBUS DP Address Set this FD-10 PROFIBUS DP address.
Number of I/O Modules Set the number of I/O modules used by this FD-10.
Module 1 and up to selected “Number of I/O Modules”
will be used by FD-10.
I/O module 1–4 > I/O module 1
Data type Select data type for I/O module 1.
Module type Select module type for I/O module 1.
Data length Set data length of I/O module 1. Note that data length is
related to selected data type, byte or word. Byte has a
length of 8 bit and word 16 bits.
Identifier [hex] Show the resulting identifier in hex.
The same content for all I/O modules, 1 to 8. Module 1 and up to selected
“Number of I/O Modules” will be used by FD-10.
