Similarly:
REMOTEOUT.1.2 = 255
will set the state of all of the outputs on node 2 to 255 decimal.
The second method uses the
REMOTEINX
and
REMOTEOUTX
keywords and accesses individual inputs
or outputs. Each input/output can either be ON (1), or OFF (0).
For example:
? REMOTEINX.1.2.0
will read the state of input 0 on node 2.
The command:
? REMOTEOUTX.1.2.0
will read the state of output 0 on node 2.
Similarly,
REMOTEOUTX.1.2.0 = 1
will set the state of output 0 on node 2 to ON (‘1’).
B.2.9.2 Analog I/O Access
Analog inputs and outputs can have any value between 0 and 100. This value will represent a voltage
equal to the specified percentage of the full-scale voltage; please see the manufacturer’s instructions.
For example:
? REMOTEADC.1.2.0
will read the value of analog input channel 0, on node 2.
The command:
? REMOTEDAC.1.2.3
will read the value of analog output channel 3, on node 2.
Similarly,
REMOTEDAC.1.2.3 = 100
will set the value of analog output channel 3, on node 2, to 100.
B.2.9.3 Extra Analog I/O Functionality
Mint provides some extra functionality with analog input nodes. The value of an analog input will often
change constantly. This can cause a lot of CAN ‘traffic’ to be generated if the node is event driven
because the node will generate a CAN message every time the input changes. The
REMOTEMODE
keyword is provided in Mint to allow the user to set the analog node to either Event (0) or Cyclic (1)
mode. Setting it to Cyclic mode will force the node into generating CAN messages on a cyclic basis, in
synchronization with a SYNC message that is generated by the network manager. This will help reduce
CAN traffic and also allow the user to predict the level of activity on the CAN bus more easily.
The following example will set the analog input channels of node 2 to Cyclic mode:
REMOTEMODE.1.2 = 1
Running in Event mode will cause a CAN message to be generated every time the input changes.
