CJ-series CompoNet Master Unit Operation Manual for NJ-series CPU Unit (Cat. No. W493)
The Slave Unit that can participate for each node address is registered in
a table so that only the registered Slave Units can participate. If the par-
ticipating network Slave Units do not agree with the table, *_RegTblErr
(Registration Table Verification Error Flag) will change to TRUE. The
Registration Table is created automatically or manually edited from the
CX-Integrator.
Connect Flag and Communication Error Flag for each Slave Unit
• Connect Flag: Changes to TRUE and remains TRUE if the Slave Unit
joins the network even one time after system power is turned ON.
• Communication Error Flag: Changes to TRUE if the Slave Unit cannot
communicate with the Master Unit for any reason after the Slave Unit
has joined the network (i.e., when the Connect Flag is TRUE). (This
Flag changes to FALSE when the error is reset.)
*_SlavDupErr (Slave Unit Duplicated Address Error Flag) and
*_SlavAllAlmSta (Representative Alarm Status Flag)
• Connect Flag and Communication Error Flag for each node address for
which a Slave Unit is registered in the Registration Table
• *_RegTblErr (Registration Table Verification Error Flag)
• *_SlavAllCnctSta (All Registered Slave Units Participating Flag)
Note The Registered Slave Unit Participation Monitoring Time can be set
(verification error check timing). Registered Slave Unit Participation
Standby Mode can be set. (Remote I/O communications will not
start until all registered Slave Units are participating.)
