Omron NSJ CONTROLLERS - 03-2008 Operation Manual page 55

Application Precautions
24
• Serial port C (on the Controller Section) has the same functionality as the
RS-232C port on a CJ1-H CPU Unit with unit version 3.0 except that a
Programming Device cannot be connected to serial port C. Connect the
Programming Device to the USB port or one of the serial ports (port A or
B).
• There is no peripheral port and a Programming Console thus cannot be
connected. Use the device monitoring function on the System Menu of the
Display Section for simple present value monitoring, present value set-
ting, and similar operations.
• Set the same network address for the built-in Ethernet on the System
Menu of the Display Section and in the routing tables of the Controller
Section.
• When routing tables are transferred to the NSJ Controller from a Pro-
gramming Device, the built-in DeviceNet Section, Expansion Unit, and
Display Section of the NSJ Controller will be reset to enable using the new
routing tables. Always confirm that resetting these parts of the NSJ Con-
troller will not adversely affect the system before transferring the routing
tables.
• A communications error will occur when a Programming Device is con-
nected to the NSJ Controller and the Display Section is reset as a result
of transferring the routing tables. After the Display Section is restarted, it
may be necessary to connect/disconnect the Programming Device's
online connection.
• An NS-AL002 RS-232C/RS-422A Conversion Unit cannot be connected
to serial port C. If the NS-AL002 is connected to serial port A on the
NSJ5-@@@@-@@@, it will not be physically possible to connect serial port
C. If the NS-AL002 is connected to serial port A or B on the NSJ8/10/12-
@@@@-@@@, serial port C cannot be used.
• Memory Cards are formatted before they are shipped. The user does not
have to format them before use. To reformat a Memory Card after use,
always use the CX-Programmer and format it in the Memory Card slot of
the Controller Section (MC (CONTROLLER) slot). The NSJ Controller
may not recognize a Memory Card that was formatted on a personal com-
puter. A Memory Card formatted on a personal computer may not be
usable with the NSJ Controller even after reformatting the Memory Card
in the NSJ Controller.
• Applications started with the external application startup function of the
Display Section of the NSJ Controller cannot use the Programming Con-
sole function for the Controller Section. These can be used only for PLCs
connected to serial port A or B of the NSJ Controller.
• Always use RecoverUpdata_6_5 NSJ_HSH or a higher version ("6_5" is
shown as version V6.5) when using the recovery/update function for the
Display Section of the NSJ Controller. Data older than version 6.5 cannot
be used with the Display Section of the NSJ Controller.
• A DeviceNet multidrop connector cannot be connected to serial port B on
the NSJ5-@@@@-@@@. Do not use it. DeviceNet multidrop connectors
cannot be used with the NSJ8/10/12-@@@@-@@@.
