The signals boxed in thick lines in the above figure are used in the FS0
operators panel.
+24V is used as the common of such signals and the power source of the
inside of the operators panel. Therefore, 0V and +24V of upper figure
must be connected.
For +24V, this operators panel requires 0.5A. In the above figure, each
of +24V and 0V uses one pin only. For securer connection, however, it
is recommended to use as many pins as possible in addition to the above.
The CNC directly monitors this signal at fixed address.
For the connection, refer to the Function volume (B–62753EN–1) of the
connection manual.
Since these signals are directly input to the PMC, process them directly
by the PMC ladder program.
For the connection, refer to the Function volume (B–62753EN–1) of the
connection manual.
The key switch signal is decoded into the bit image at the PMC address
R by the management software of the PMC. Whether the necessary key
is depressed or not can be known by checking the bit image of the key
switch by the PMC ladder program of the user. (Refer to Table 6.7(a), (b),
(c))
The key switch signal address (Xn Xn+2 on Table 6.7(a)) and its bit
image address (Rk Rk+7 on Table 6.7(b), (c)) are optionally assigned
to the proper and unused address. (On FS0, each address is fixed to X20
, F292.)
