8. Select "YES".
– Press "YES" if the display corresponds to the current mounted
status of the I/O modules. The I/O module setting is updated, and
the IO MODULE window changes to the EXTERNAL IO SETUP
window.
If the display does not indicate the actual mounted status,
recheck the cable connection and the switch setting. The
following causes are suspected.
• Improper setting of I/O communications
Setting of TM4 on the XFB01B board may be improper.
XFB01B board would not be recognized properly if this
condition is applied.
• Improper setting of switching boards.
Setting of TM5 on the XFB01B board may be improper.
XFB01B board would not be recognized properly if this
condition is applied.
• Improper or overlapped station settings
SW4 might be set to 0, E, or F (impossible setting value).
Additionally, only one optional board can be set for each
station. Change the SW4 setting, and make sure that no
NOTE
stations overlap.
• Improper connection of the 24VDC power cable and the I/
O communication cable
The 24VDC cable and the I/O communication cable may
not be connected properly. Incorrect connection of the
24VDC power cable to the right position of CN1 may lead to
improper power supply to the board. Recheck the cable
connection referring to the Section 4 "Mounting XFB01B
Board" on page 4-1.
• I/O module failure
When the above causes do not apply, and the display still
does not correspond to the actual mounted status, failure of
an I/O module is suspected. Contact your YASKAWA
representative.
• The number of XFB01B(MASTER) which can be mounted
is two boards at the maximum.
