analogue input falls below a preconfigured fault level. The current SILBUS channels of the
fault signals can be displayed by simply entering the command name as shown in the
example below:
TX4A::>SBFALT
Under Level Fault Silbus Addresses are:
Input [1] Fault Address = J2
Input [2] Fault Address = A6
Input [3] Fault Address = A7
Input [4] Fault Address = B3
TX4A::>_
If the command name is entered with additional attributes the channel addresses can be
configured to any valid SILBUS address. There is no restriction on the SILBUS addresses;
they do not have to be in numerical order or from the same group. An example of
configuring input 2 is shown below:
TX4A::>SBFALT SET 2 K7
Setting Changed
Input [1] Fault Address = J2
Input [2] Fault Address = K7
Input [3] Fault Address = A7
Input [4] Fault Address = B3
TX4A::>_
The above example shows the format of the command when the address is configured.
The keyword “SET” is required to invoke a change; the number of the TX4A input is next,
followed by the SILBUS channel address. If a TX4A input is not to be used then it should
not be assigned a SILBUS channel address. The keyword “DISABLE” is used when a
SILBUS channel is not required.
TX4A::>SBFALT SET 2 DISABLE
Setting Changed
Input [1] Fault Address = J2
Input [2] Fault Address = DISABLE
Input [3] Fault Address = A7
Input [4] Fault Address = B3
TX4A::>_
6.11 FAULT LEVEL COMMAND
This command is used to display and configure the under level fault trigger point for each
of the analogue inputs. The fault trigger point allows the analogue transmitter to detect
input signals that are out of range (less than 4mA) or open circuit. The fault level is
entered as a mA level for example 3.80. This would cause a fault to be generated
whenever the input signal fell below 380mV for a 0.4 to 2.0V input signal or 3.80mA for a
