Configuring Alarm/Control Setpoints
The PM135 has an embedded logical controller that can perform different
actions in response to user-defined internal and external events. Unlike a
PLC, the meter uses a simplified programming technique based on
setpoints that allows the user to define a logical expression based on
measured analog and digital values that produce a required action.
The meter provides 16 control setpoints with programmable operate and
release delays. Each setpoint evaluates a logical expression with one
trigger argument. Whenever an expression is evaluated as “true”, the
setpoint performs a programmable action that can send a command to the
output relay, or increment a counter.
The logical controller provides very fast response to events. The scan time
for all setpoints is 1 cycle time (16.6 ms at 60Hz and 20 ms at 50/400
Hz).
