Figure A-2 Case: Necessary for additional setting by nV-Tool (Byte-swap mode)
Note
• Scope of byte-swap mode is word-type.
• To enable Byte-swap mode, it is necessary to set the Operation mode switch 3 ON. Confirm
the PA912 Firmware version V2.2x or later and nV-Tool V4.8.3 later, before you enable the
switch No.3 ON.(more information about how to use the byte-swap mode, refer 3.3.2)
• After you set the switch No.3 ON for enabling the Byte-swap mode, Do not forget the restart
PA912 with the Maintenance switch.
• While Byte-swap mode ON, the performance of exchanging Input data and output data
between TC-net I/O Loop and PROFIBUS Slave I/Os will get worsen about 20persent at
worst case, compared Byte-swap mode OFF.
• If the Byte-swap mode OFF with switch No.3 OFF, factory default settings, PA912 ignore the
Byte-swap command from nV-tool.
