7.1 Point to point and Addressed, serial transfer slave, FD-10 P
Point to point transfer
Continuous transfer of defined PROFIBUS I/O data modules from this FD-10 to an
other FD-10.
All by FD-Tool defined PROFIBUS I/O modules will be mirrored between the two
FD-10’s. Input modules of FD-10 at one side will be sent to output modules of FD-10
at the other side, and vice versa. However, note that there will be a time delay which
depends on the serial transfer time.
FD-10 continuously transfer I/O data, or try to initiate continuously transfer in the
initially stage, when the unit is in normal operation mode and the PROFIBUS DP is active,
LED CONF inactive and BA active.
Master controlled transfer (Addressed)
Wait for a received serial transfer frame including this unit’s serial transfer address.
After a correct received frame, an I/O data frame will be sent back once.
All by FD-Tool defined PROFIBUS I/O modules will be mirrored between this FD-10
and the FD-10 at the other side. Input modules of FD-10 will be sent to output modules
of FD-10 at the other side, and vice versa. Note that command and status data (including
this unit’s serial transfer address) will not be included in PROFIBUS I/O data of this
FD-10.
FD-10 can receive frames when the unit is in normal operation mode and the PROFIBUS
DP is active, LED CONF inactive and BA active.
