retained from the invoking application. The corresponding Address field automatically detects
and contains the address associated with the Symbol.
♦ If a Symbol has not been selected, in an Address field, type in a direct word or bit address to
monitor.
Note: Address notation for CS/CJ/CP-series PLCs and CV-series PLCs is, for instance ‘D0’,
‘0’, ‘E0.0’ to monitor a word, ‘0.0’, ‘cf100’ to monitor bits.
When monitoring starts, data from the PLC is displayed in the Value field, in the format
specified in the Format field. The display format of the address or symbol to be monitored can
be changed by selecting an appropriate button from the toolbar: Binary, Binary Coded
Decimal, Decimal, Signed Decimal, Hexadecimal or Text.
Any special address information is shown in the Attribute field. The attribute of a bit can be forced. It is not
possible to force bit addresses that are read-only. Use the following procedure to apply a forced setting.

2. Select the Attributes setting for the bit.
3. Select the forced state of the bit. A bit can be forced on by selecting the Force On button
from the toolbar. A bit can be forced off by selecting the Force Off button from the toolbar.
Forced settings can be cancelled by selecting the Force Cancel button from the toolbar.
