The device list can be displayed in any of the following three formats.
Format
Description
Node address order
Devices are listed in ascending node-address order. The
device type (Master/Slave) isn’t a factor in the list.
Remote I/O
communication
The devices are listed in a Master-based tree format. The
Slaves participating in remote I/O communications with
the Master are listed in ascending node-address order.
Any Slaves that aren’t participating in remote I/O
communications with a Master are listed after the tree.
Message
communication
configuration
The devices are listed in a node-based tree format. Any
other nodes participating in FINS message
communications with the node are listed in the tree. The
nodes are listed in ascending node-address order.
Nodes involved in two-way FINS message communication
will each be listed in the other node’s tree configuration.
Any nodes that aren’t participating in message
communications are listed after the tree.
The information on devices read through the network can be saved and
retrieved as a “network configuration file.”
This function displays the status of the specified OMRON Master Unit. The sta-
tus of Slaves involved in remote I/O communications with the Master will also be
displayed.
This function displays the status of the specified MULTIPLE I/O TERMINAL
(DRT1-COM Communications Unit). The configuration of I/O Units connected to
the Communications Unit will also be displayed.
This function reads and displays the error history stored in the specified OMRON
Master Unit. The error history information in the specified Master can be cleared.
This function displays the communication cycle time of the specified OMRON
Master Unit. The current communication cycle time will be displayed along with
the maximum and minimum communication cycle times recorded since the
Master Unit was started or reset. The maximum and minimum times can be reset
to restart these measurements.
Operating Functions
This function can be used to start or stop remote I/O communications (I/O com-
munications with Slaves) for the specified OMRON Master Unit.
When there are two or more Masters in the network, each Master’s remote I/O
communications can be controlled separately.
