Appendix 1
The following explains the on/off timings and conditions of the I/O signals shown in "I/O Signal List" (refer to
Page 45, Section 3.5):
(1) Module error: Xn0
This signal indicates whether the module is normal or faulty.
OFF: Module normal
ON: Module error
Module error
(Xn0)
Module ready
(XnF)
(2) Host data link status: Xn1
This signal indicates the data link status of the host station.
SB006E also represents the same meaning. For programming, use either Xn1 or SB006E only.
Note that the ON/OFF condition for Xn1 is opposite to that for SB006E. When Xn1 is used, the condition is as
follows:
OFF: Data link is stopped
ON: Data linking in progress
(3) Other station data link status: Xn3
This signal indicates the data link status of other stations (device stations).
The SB0080 signal has the same contents. For programming, use either Xn3 or SB0080 only.
OFF: All stations normal
ON: There is a faulty station (the faulty station status is stored in SW0080 to SW0083)
The other station data link status (Xn3) takes up to 6 seconds to turn on after a device station connected to the master/local
station becomes faulty.
The time to turn ON differs according to the system configuration, faulty status or other conditions.
