You are ready to start receiving and transmitting remote I/O information.
An LED is provided on the 9/440 resolver–based CNC processor board
and is visible from the bottom of the system module. As remote I/O
responds to commands, you should see this LED pattern:
LED Status Description
Green
R–I/O LED ON Active Link to PLC. This is the normal state when the
RIO link is active.
FLASHING The remote I/O link is active but the PLC is currently in
program mode.
OFF Remote I/O link is offline. The port is not being used,
not configured in AMP correctly, not turned on with
$RMON, or not attached to a 1771 device.
Two auxiliary analog outputs are provided through the connectors labeled
TB2 and TB3 of the 9/440 resolver–based wiring board. These connectors
are typically used to command external analog spindle drive systems but
can also be configured in AMP to control additional analog servo systems.
Figure 5A.23 shows the location of ANALOG OUT connector and lists
terminal assignments of this connector.
Important: If positioning feedback is required for the spindle or analog
servo system, its corresponding encoder feedback should be wired through
one of the encoder feedback connectors and indicated as such in AMP.
