added to the configuration up to the upper limit of five set points per input channel. 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 adding a new set point to input 2 is shown below:
TX4A::>ADDPT SET 2 H2 R 6.3
Setting Changed
Analog Input 1
1: G1 Trips on rising edge at 14.0mA
2: G2 Trips on rising edge at 15.1mA
3: G5 Trips on rising edge at 16.0mA
4: G8 Trips on rising edge at 17.3mA
5: !G3 Trips on rising edge at 18.0mA
Analog Input 2
1: H2 Trips on rising edge at 6.3mA
Analog Input 3
No Set Points
Analog Input 4
1: J1 Trips on falling edge at 16.5mA
2: J2 Trips on falling edge at 16.0mA
TX4A::>_
The above example shows the adding of a set point to analogue input 2. The keyword
“SET” is required to invoke an addition; the address of the SILBUS digital channel is next,
followed by the
keyword “R” for rising alarm and the value of the set point level in
milliamps. The exclamation mark should be used in front of the channel address if
inverted transmission is required i.e. fail safe operation. The set point value can be any
value between 4.0mA and 20.0mA in 0.1mA steps.
6.13 SET POINT DELETE COMMAND
This command is used to display or delete set points from the analogue inputs. The
current configuration of the set points can be displayed by simply entering the command
name as shown in the example below:
TX4A::>DELPT
Analog Input 1
1: G1 Trips on rising edge at 14.0mA
2: G2 Trips on rising edge at 15.1mA
3: G5 Trips on rising edge at 16.0mA
4: G8 Trips on rising edge at 17.3mA
5: !G3 Trips on rising edge at 18.0mA
Analog Input 2
1: H2 Trips on rising edge at 6.3mA
Analog Input 3
No Set Points
Analog Input 4
1: J1 Trips on falling edge at 16.5mA
2: J2 Trips on falling edge at 16.0mA
