Output Enable
Signals module that communications has been
interrupted to the network. Output modules should
execute their fault routine or go to safe state.
On power-up, the module remains OFF, 0mA out.
After normal power-up, this bit must be set to a “1”
by user program to begin normal module functioning.
If the bit is reset to “0” by a communication fault, the
module should use the information contained in the
Module Safe State data until the value is set to “1”,
when normal function continues.
Analog Fault State
Determines how module reacts to faults when
channel is used in analog normal mode.
Range: 0 = go to minimum value of data range, 1 = go
to maximum value of data range, 2 = hold last state, 3
= 50% of data range.
Digital Fault State
Determines how module reacts to faults when
channel is used in digital mode.
Range: 0 = reset, 1 = hold last state.
Fault Mode
Selects whether the channel pair fault detection is
enabled or disabled. There is a 100Hz (10ms) filter for
wire-off/lead-break detection.
Range: 0 = disable, 1 = wire-off fault detection
enabled.
