SING A COUNTER
(
EXAMPLE
)
Using the counter will take three steps:
1. Preparing the instrument (setting correct values for mode, limit etc.)
2. Monitoring the alarm info byte (gives info which alarm has occurred)
3. Resetting the counter (will re-initialize the counter and set output to normal values again)
7.11.1 Using a batch counter
The measured signal will be integrated in time and there will be a check on a certain limit set by the user.
Example
Send following parameter values:
Action Parameter Value
The batch is reached at 1000 ln. send to Counter limit 1000.0
New setpoint when reaching the limit to 0%
(valve should be closed).
send to Counter setpoint mode 1
send to Counter new setpoint 0
Reset should be enabled via BUS/RS232 or by
means of keyboard/micro-switch.
send to Reset counter enable * 5
Set counter to batch counter. send to Counter mode 2
*) Default all reset inputs are enabled, so this command isn’t really necessary
Now the counter will be active.
Alarm / Counter status can be monitored by means of parameter alarm info.
Resetting the counter will need the following command reset = 0 and then reset = 3.
To inactivate the counter, put it in counter mode “off”. This will also reset your outputs.
This can be done sending command: counter mode = 0.
