Remote Control Inputs
net_remote_in
is a network remote load or process control reference input. The
DSLC control hardware remote input must be at 0.0 mA for the network remote
input to operate. The remote input has a times-1000 scaling (that is, 20000 would
represent 20.0 mA, and 4000 would represent 4.0 mA).
net_process_in
is a network input from a LonWorks-compatible process
transmitter. The DSLC control hardware process input must be at 0.0 mA for the
network process input to operate. The process input has a times-1000 scaling
(that is, 20000 would represent 20.0 mA, and 4000 would represent 4.0 ma).
net_discrete_in
is a network input from a remote sequencer. The input must be
in the same format as hw_discrete_in described above. All inputs must be written
each time the network discrete input value is updated. The hardware discrete
inputs must not be used when the network input is used.
