3.1.6 Fault Behavior
The first five bits of the Remote I/O System area are used to determine the
fault behavior of the Remote station. The master station has to send the infor-
mation of these bits to the Remote station with the initial data. The following
table shows the possible settings of these bits.
System I/O
Bit No.
Setting Description
0 Power On (station is restarted after fault is corrected and
power is cycled on)
0
Restart after T-
Bus error
1 Autoreset (station is restarted automatically after fault is
corrected)
00 (0) Stop process cycle
01 (1) Set outputs to zero
10 (2) No reaction
1,2
Reaction on F-Bus
error
11 (3) Not used (internally switched to 2)
00 (0) Leave dataexchange, (station is taken from CC-Link bus)
01 (1) Set inputs to zero
10 (2) No reaction
3,4
Reaction on T-Bus
error
11 (3) Map errorinformation to fieldbus, (4 words for errorinfor-
mation are copied to Remote Register RWrm0-RWrm3, for
details see next table)
Following table shows the detailed errorinformation:
Register number Description Range Default
RWrm0 general errorbyte
Bit 0.0 fieldbus error 0 / 1 0
Bit 0.1 modulbus error 0 / 1 0
Bit 0.2 module error (I/O) 0 / 1 0
Bit 0.3 coupler error 0 / 1 0
RWrm1 errorcode (configuration error) 0 - 65535
if Bit 0.1 = 0 bitlength of modulbusRWrm2
if Bit 0.1 = 1 errorcode at modulbus error 0 - 65535
if Bit 0.1 = 0 number of modulesRWrm3
if Bit 0.1 = 1 modul No. where error occurred
3.1.7 Initial Data Transfer
After power-on or hardware reset, the CC-Link coupler 750-310 requests its
initial data (i.e. the system bits for faultbehavior) from the master station as
described below.
