•
Time base (counters) – Use to set the period over which counting will take
place.
•
Low/High states (digital inputs) – Short text messages displayed on the
meter depending on the high or low state of the selected digital input.
•
Timeout (Modbus) – A feature of Modbus inputs is to change their value if
data updates have not occurred within a certain time. There is also a setting
for the value to use at power up before any data is written to the register.
There are 4 timeout actions:
1.
Set to fixed value: After the timeout, the process (or control process)
will use the specified fixed value.
2.
Fixed + error: Same as above but also the process (or control process)
will have its internal error flag set. A meter configured for this process
will display TIMEOUT.
3.
Keep last value: After the timeout, the process (or control process)
will continue to use the value in the register.
4.
Keep last + error: Same as above but also the process (or control
process) will have its internal error flag set. A meter configured for
this process will display TIMEOUT.
During the power up stage (before the first value is written to the register)
the process or control process will have its internal error flag set and, if
configured for a meter, it will display “NO DATA”.
5.
Press
OK.
When a process is created its name appears on its corresponding button on the Processes
menu screen. If a button displays the word “Disabled” then it will not acquire a signal
from its respective input and any meters assigned to it will not be displayed on the Meter
screen.
