Limitations
• When the parameter settings have been made with Windows fonts, parameter symbols (%PxS)
are shown as they are in the alarm messages to be displayed.
• For parameter Nos. 0 to 8 specified in the [Parameter Table] dialog, the maximum allowable
number of words is 128 (automatically calculated*). Be sure to use 128 or fewer words in total.
* To see the number of words used, check "Record Parameters" in "Buffering Area Setting" page
9-3.
• In the event of a failure to read parameter memory, "****" is displayed in place of the parameter in
the message.
• If [Message No.] is selected for [Display Type] in the [Parameter Table] dialog and if the
corresponding message includes parameter symbols, the symbols "%PxS" appear as they are
when the message is displayed.
• If [Total Frequency of Occurrence Display] or [Total Time of Occurrence Display] is selected for
alarm history display, the parameter symbols in alarm messages are displayed as "****".
• If changes are made to the data in the [Parameter Table] dialog, such as the number of
parameters, the order of parameters, or the assigned memory addresses, after the execution of
data sampling and then if screen data transfer is performed in this condition, the data previously
sampled may not be displayed correctly on the screen. Whenever any changes as mentioned
above have been made, formatting is required before sampling start.
• Real-time printing of alarm logging data will show parameters as "****".
• In the case of alarm logging, the parameters will be displayed to indicate alarm bit set (ON) and
reset (OFF) conditions.
• When [Occurrence/Cancellation Time] is selected for the history display associated with alarm
tracking, the parameters will not be displayed for alarm bit reset (OFF) conditions.
