CompoNet Networks Section 1-1
• Editing and transferring registration tables
• Setting Input Data Zero Clear Mode for when communications error occur
• Setting I/O Communications Manual Startup Mode
• Monitoring Master Unit status
• Monitoring the Master Unit error history
• Monitoring Slave Unit network participation status
• Setting and transferring Slave Unit parameters
• Monitoring Slave Unit information
• Managing files
• Managing hardware (EDS files)
■ Smart Slave Unit Functions
The Slave Units provide Smart Functions that can record various added-value
information in addition to the ON/OFF signals (I/O data). This enables preven-
tive system maintenance (including operation time monitoring and contact
operation counter monitoring) and aids in faster system introduction (including
communications power voltage monitoring and I/O power status monitoring).
Settings are possible from either the CX-Integrator or through message com-
munications.
■ Master Unit Detection of Network Participation, Errors, and Status
When a Slave Unit joins the network, a bit corresponding to the node address
called a Participation Flag will turn ON. If a Slave Unit that has been partici-
pating in the network leaves the network, a bit corresponding to the node
address called an Error Flag will turn ON.
Network status, such as communications errors and redundant Slave Unit
node address, and Slave Unit diagnostic results are detected by the Master
Unit and display on the seven-segment display on the front panel and
reflected in the Status Flags.
■ Registration Tables
Tables of the Slave Unit that should be participating at each node (i.e., the
node address and corresponding Slave Unit model number) can be registered
from the CX-Integrator to verify the Slave Units actually participating in the
network and prevent unregistered Slave Units from participating in the net-
work. A monitoring time for registered Slave Unit participation after power is
turned ON can also be set.
Remote I/O communications can be stopped until all registered Slave Units
are participating and remote I/O communications can be started as soon as
all registered Slave Units are participating (called Registered Slave Unit Par-
ticipation Standby Mode).
■ Stopping Communications at Communications Errors
A DIP switch on the front of the Master Unit can be set to stop remote I/O
communications when a communications error has occurred in any of the
Slave Units.
■ I/O Communications Manual Startup Mode
I/O Communications Manual Startup Mode can be set from the CX-Integrator
so that remote I/O communications are not started when the power is turned
ON. Remote I/O communications will not start until the Remote I/O Communi-
cations Start Switch is turned ON in memory.
