Multivariable
Multiplexer (MUX)
A PROVOX highway device that transfers information between the data
highway and field devices (both analog and discrete).
Multiplexer Analog Input (MUX AI)
A PROVOX point type, available from the multiplexer. A MUX AI point
consists of a single analog value that represents the voltage or current
signal of a multiplexer analog input channel.
Multiplexer Analog Output (MUX AO)
A PROVOX point type, available from the multiplexer. A MUX AO point
consists of a single analog value, provided by a console operator or a
system device, that appears as the voltage or current of a multiplexer
output.
Multiplexer Discrete Input (MUX DI)
A PROVOX point type, available from the multiplexer. A MUX DI point
consists of a single-bit digital value that represents the signal present at
a multiplexer discrete input channel.
Multiplexer Discrete Output (MUX DO)
A PROVOX point type, available from the multiplexer. A MUX DO point
consists of a single-bit digital set point, provided by a console operator or
a system device which appears at a multiplexer discrete output chanel.
Multiplexer Pulse Count Input (MUX PCI)
A PROVOX point type, available from the multiplexer. A MUX PCI point
is a single value, from 0 to 65535, representing the number of discrete
pulses received at a multiplexer pulse count input channel.
