4.2.17 Trip Analog Monitor (setpoint and line monitor)
An input signal op2 (op1 = live or dead zero) in converted into engineering units using
op3 = beginning o.r. and op4 = full scale.
The result is stored in op12. The signal will then be monitored for line interrupts and
overrange (Fault) plus a setpoint (op5) depending on op6 = low limit or high limit.
Example
ANA,Z01,AE1,K01,K02,K03,Z00,X01,K04,X03,X04,X05,X06
Comment
Line monitor trips at
op1 = input mode 0 = dead zero (21 mA)
1 = live zero
(3.6 mA and 21 mA)
2 = live zero (0.5 mA and 21.5 mA)
The reset variable op7 is used to clear alarm or fault conditions. This allows you to HOLD
the Alarm and RESET it via a variable value (op7) under software control. The variable
may be governed by an analog input or the front push buttons.
The alarm will be delayed by op8. The delay will reach 1 second, if op8 = 25 and the
average program execution time is estimated to be 40 ms.
If an alarm or fault are detected this information will be stored. If both fault and alarm are
detected, fault will be predominant.
Memory cells op9 to op11 may only be read during the remaining program. They must
not be overwritten.
Call ANA,op1,op2,op3,op4,op5,op6,op7,op8,op9,op10,op11,op12
ANA = analog input monitor
op1 = input mode
op2 = input
op3 = beginning of range
op4 = full scale
op5 = trip point
op6 = trip mode (0=low limit; 1=high limit)
op7 = Reset (> 0 then reset)
op8 = delay (delay = op8 x program cycle)
op9 = delay counter
op10 = alarm memory
op11 = line interrupt/overrange (fault)
op12 = analog output
Formula op10 = 1 for alarms or if op10 was 1 before
op10 = -1 while inside deadband
op11 = 1 for fault or if op11 was 1 before
op11 = -1 while inside deadband
