7. Press {ENTER}.
– A confirmation dialog box appears.
8. Select {YES}.
– When the mounted status of an I/O module is correct, select "YES."
The I/O module setting is updated, and the IO MODULE window
changes to the EXTERNAL IO SETUP window.
If the displayed details of each station (ST#) and the
installation status of I/O modules are different, check the
settings of cables and switches again. The following
causes are possible:
(1) Wrong I/O communication setting
The setting of SW1 or SW2 of the
JANCD-YEW01-E board may be wrong. If so, the
board cannot be determined correctly.
(2) Wrong station setting
S1 may be set to 0, E, or F (not available).
Also, only one optional board can be set to one
station. Change the setting of S1 so that two or
more boards are not set to one station.
NOTE
(3) Wrong connection of the 24 VDC power cable or the
I/O communication cable
The 24 VDC power cable or the I/O communication
cable may not be connected correctly. If the 24
VDC power cable is not connected to CN324
correctly, the power cannot be supplied properly.
Check the connection of cables according to
chapter 4 "Board Installation".
(4) Failure of I/O module
If the displayed details and the installation status are
still different even after the correction above, failure
of the
I/O module is possible. Contact your Yaskawa
representative.
