Graphic Nodes
Two graphic nodes reside on the CAN Bus. Each graphic
node contains a display module and graphic controller. The
screen images themselves are contained in the code of the
graphic node. Data values to display within the screen
images, are passed to the graphic nodes over the CAN Bus.
Wind Speed Remote Input Node
A wind speed remote input node is used at the luffing jib. The
node provides power to the wind speed sensor and reads the
analog data output of the sensor. Wind speed RIN output
data connects to the luffing jib RIN and is a serial data
output. The data is passed from the luffing jib wind speed
RIN to the luffing jib RIN, then to the boom RIN, and finally
onto node 0.
Boom and Luffing Jib Remote Input Nodes
The boom RIN contains digital inputs to read the block-up
and jib angle limit switches. The boom RIN also provides
power to the boom angle sensor and reads the analog data
output of the sensor.
Boom RIN data connections connect to node 0. Boom RIN
data is not communicated over CAN Bus, but rather over a
serial data output that node 0 reads.
The luffing jib RIN contains digital inputs to read the block-up
limit switches. The boom RIN also provides power to the
upper and lower load pin sensors and the luffing jib angle
sensor and reads the analog data outputs of these sensors.
Luffing jib RIN output data connects to the boom RIN and is a
serial data output like the boom RIN. The boom RIN then
passes the luffing jib data to node 0.
