- 32 -
NOTE
For the operation mode, pay careful attention to the
following points:
(1) When the power is turned on in the status in which
at least one slave station is ACTIVE, the master
station automatically starts in the OPERATE mode.
An ACTIVE slave station means a slave station for
which ENABLE and SLAVE TYPE = 192 are set as
slave parameters.
(2) In a case other than (1), that is, when the power is
turned on in the status in which all slave stations
are not ACTIVE, the master station automatically
starts in the STOP mode.
(3) A FANUC master station cannot manually be put in
the OFFLINE mode.
If a FANUC master station is in the OFFLINE mode
immediately after power-on, an error may occur.
See Table 1-1, "Setting Error Message."
A message may be displayed at the lower left of Screen 1-8. In this
case, take appropriate action, referencing the table below.
Table 1-6 Mode screen message
