Monitoring
Use the Programming Console to write the initial parameters to the output word
of the Unit.
1. Execute the operation mode A set command or operation mode B set com-
mand to determine the operation mode.
2. Determine the scaling values.
3. Determine the set values if the Unit is used in comparison mode.
4. Execute the operation mode A set command to determine the hysteresis if
the timing hold type is set to normal.
Use a ladder program to retrieve the input word data for monitoring. The input
word data is the scaled conversion data if the Unit is in measurement mode. The
input word data is a comparison result if the Unit is in comparison mode.
Note The scaling values and zero shift value will be reset to the factory-set values. if
the input type is changed with the operation mode A set command. Be sure to set
the scaling values and zero shift value properly after the input type is changed
with the operation mode A set command.
The command operation examples in the following section are described on the
condition that the output word state before and after command operation be set
to "0000."
It must be noted that, if the Unit is used in the set data D/A output mode, the out-
put is specified to be 0 V. Therefore, set a desired output value instead of "0000"
in actual operation.
