(11) Remote device station initialization procedure registration function
This function performs the initial setting for the remote device station using the
GX Developer, without creating a sequence program (see Section 4.4.1).
(12) Event issuance for the interrupt program
This function issues an event when the conditions set by the GX Developer are
established in order to make the PLC CPU execute the interrupt program (see
Section 4.4.2).
(13) Automatic CC-Link startup
By installing the QJ61BT11N, the CC-Link is started up and all data are refreshed
by simply turning on the power, without creating a sequence program. However,
when the number of connected modules is less than 64, it is necessary to set the
network parameters in order to optimize the link scan time (see Section 4.4.3.).
(14) Selecting a mode according to the system
The CC-Link system has four types of modes according to various systems. (See
sections 4.4.4, 4.4.5 and 4.4.14.)
The overview of the modes is described in the following table.
Connectable
Remote I/O station
Remote device station
Intelligent device station
Local station
Standby master station
Remote I/O station
(15) Reserved station function
Stations that are not actually connected (stations to be connected in the future)
will not be treated as faulty stations if they are specified as reserved stations.
The reserved stations can also be set as 0 points. (see Section 4.4.6).
Station number 3
Remote station
(occupies 1 station)
Mode in which complete compatibility with the
conventional module (QJ61BT11) is achieved.
Select this mode when the number of cyclic points need
not be increased or when the QJ61BT11N is used to
replace the conventional module as a maintenance
product.
Select this mode when increasing the number of cyclic
points and configuring a new system.
Select this mode when adding a ver.2 compatible slave
station to the existing system to increase the number of
cyclic points.
Select this mode when the system consists of only the
master station and remote I/O stations.
Since cyclic transmission is made at high speed, the link
scan time can be reduced.
