A Programming Device connected to the USB port, a Toolbus port (serial port
A or B), or the built-in Ethernet port of the NSJ Controller can access and per-
form operations for a CS/CJ-series PLC on the same network.
A Programming Device connected to the peripheral port or Host Link port of
the NSJ Controller can perform operations, set up DeviceNet, and set up Con-
troller Link data links for the Controller Sections of the NSJ Controllers, but it
cannot transfer screen data to the Display Sections of the NSJ Controllers.
To transfer screen data to the Display Section of an NSJ Controller, connect
the Programming Device to the USB port, a Toolbus port (serial port A or B),
or the built-in Ethernet port of the NSJ Controller.
Routing tables must also be set in all of the NSJ Controllers. Refer to Routing
Table Setting Example on page 16 for a setting example.
When a CS/CJ-series PLC is operated via the network from Support Software
connected to the built-in Ethernet port of an NSJ Controller, the Frame Length
under the Network Settings in the Change PLC Type Dialog Box must be
changed from the default setting of 2000 to 1004 or less. Communications
cannot be executed normally if the frame length is set to 1005 or greater
because the maximum frame length of the inner bus in the NSJ Controller is
1004.
