Appendix 1 Details of the I/O Signals

The following explains the on/off timings and conditions of the I/O signals shown in "I/O
Signal List" (refer to Section 3.5):
(1) Module error: Xn0
(2) Host data link status: Xn1
(3) Other station data link status: Xn3
The other station data link status (Xn3) takes up to 6 seconds to turn on after a
slave 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.

This signal indicates whether the module is normal or faulty.
OFF: Module normal
ON : Module error
Module error
(Xn0)
Module ready
(XnF)
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
This signal indicates the data link status of other stations (slave 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)
