(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 QJ61BT11, 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 two types of modes: remote net mode and remote I/O
net mode. (See sections 4.4.4 and 4.4.5.)
The differences between the two modes are listed in the table below.
