CJ-series CompoNet Master Unit Operation Manual for NJ-series CPU Unit (Cat. No. W493)
Description
FALSE: Normal
TRUE: Error
Note Remote I/O communications will start even if this
flag is TRUE.
FALSE: Normal
TRUE: Error
Note Remote I/O communications will start even if this
flag is TRUE.
This flag is enabled only when Registration Table Enable
Mode (i.e., when SW4 (REGS) was set to ON on the
Master Unit when the power supply to the Controller was
turned ON or the Controller was reset).
FALSE: There is a Slave Unit that is not participating in
the network. (Not all of the Slave Units in the
Registration Table are participating.)
TRUE: All of the Slave Units in the Registration Table
are participating in the network.
The Connect Flags for all of the Slave Units are used to
determine when the Slave Units are participating.
Note 1 This flag will be TRUE when all Slave Units in
the Registration Table are participating in the
network, even if an unregistered Slave Unit is
also participating.
2 When the Registered Slave Unit Participation
Standby Mode is enabled, remote I/O communi-
cations will stop while this flag is FALSE.
Remote I/O communications will start when this
flag changes to TRUE.
FALSE: Remote I/O communications are stopped.
TRUE: Remote I/O communications are operating.
FALSE: User program operations are not possible. (The
user program cannot use Slave Unit I/O data in
Registration Table Enable Mode.)
TRUE: User program operations are possible. (The
user program can use Slave Unit I/O data in
Registration Table Enable Mode.)
Note Flag status is determined by a logical AND of the
value of SlavCommErr
communications error) in *_UnitSta (Status), the
value of SlavAllCnctSta (All Registered Slave Units
Participating Flag),
*_IOCycleStartSta (Remote I/O Communications
Start Switch).
FALSE: Registration Table Disable Mode. (SW4 (REGS)
on the Master Unit was set to OFF when the
power supply to the Controller was turned ON
or the Controller was reset, or the Registration
Table data is not correct.)
TRUE: Registration Table Enable Mode. (SW4 (REGS)
on the Master Unit was set to ON when the
power supply to the Controller was turned ON
or the Controller was reset and the Registration
Table data is correct.)
The value of this variable is a logical OR of the Warning
Status Flags for all Slave Units.
The value of this variable is a logical OR of the Alarm Sta-
tus Flags for all Slave Units.
(FALSE = no
and the value of
