5 Remote I/O Communications
The Registration Table is then enabled by turning ON the power supply with SW4 (REGS) on the
Master Unit set to ON. (The Registration Table is read when the power supply is turned ON.)
*_RegTblSta (Registration Table Mode Flag) in *_UnitSta (Status) will change to TRUE (Registration
Table Enable Mode).
(1) Editing and Transferring the Registration Tables
Edit the Registration Table in the Master Parameter Editing Window of the CX-Integrator.
The table shows the correspondence between the node addresses and the Slave Unit mod-
els. Download the Table to the CompoNet Master Unit.
Additional Information
Registration Tables that are either generated automatically from the CX-Integrator or edited and
downloaded are stored in EEPROM in the CompoNet Master Unit. Therefore, the Registration
Table data in the CompoNet Master Unit is saved even if the power supply to the Controller is
turned OFF or if the Master Unit is mounted to another Controller.
Registered Slave Unit Participation Monitoring Time
The Registered Slave Unit Participation Monitoring Time is the time from when the power supply to
the Controller is turned ON, from when *_IOCycleStartCmd (Remote I/O Communications Start
Switch) is changed to TRUE in the I/O Communications Manual Startup Mode, or from when the
Controller is reset, until the participation of all registered Slave Units has been detected.
The Registered Slave Unit Participation Monitoring Time can be set to a time other than the default
(10 s for any baud rate other than 93.75 kbps, and 30 s for 93.75 kbps).
Using the CX-Integrator, set the Registered Slave Unit Participation Monitoring Time (1 to 600 s;
default: 10 s at baud rate of other than 93.75 kbps and 30 s at baud rate of 93.75 kbps) under
Detailed Settings in the Master General Tab Page, and then download the parameters to the Com-
poNet Master Unit. This setting is disabled when the Registered Slave Unit Participation Standby
Mode is enabled.
Registered Slave Unit Participation Standby Mode
Registered Slave Unit Participation Standby Mode can be used not to start remote I/O communica-
tions until all registered Slave Units are participating in the network (i.e., until *_SlavAllCnctSta (All
Registered Slaves Participating Flag) changes to TRUE). Using this mode will make it faster for all
Slave Units to participate in the network.
Remote I/O communications will not start, however, unless all registered Slave Units are participat-
ing.
When this mode is used, Registered Slave Unit Participation Monitoring Time setting (including the
default value of 10 s) is disabled.
On the CX-Integrator, go to the Detailed Settings on the Master General Tab Page, and enable the
Registered Slave Unit Participation Standby Mode. Download the parameters to the CompoNet
Master Unit to enable the setting.
The Registered Slave Unit Participation Standby Mode is enabled only when Registration Table
Enable Mode (i.e., when SW4 (REGS) is set to ON on the Master Unit when the power supply to the
Controller is turned ON or the Controller is reset and the Registration Table data is normal). It can be
used with any communications mode number.
