Leading Zeros
This attribute adds leading zeros to the PLC Register Monitor when the Decimal, 4-Digit
BCD, or 8-Digit BCD format is used and the data read from the PLC register is shorter
than the number specified in the Number of Digits attribute (for example: 0024 would
display instead of 24 in 4-Digit BCD format).
To enable Leading Zeros in a PLC Register Monitor:
1. In the Register Monitor Editor dialog box, in the Special Effects group box, select the
Leading Zeros check box.
Hide Data Entry
This attribute displays asterisks in the PLC Register Monitor instead of the data read from
the PLC register or typed by the OIT operator. This allows the system programmer to
configure a process with restricted access. For example, a PLC register is configured in
the PLC ladder logic program so that whenever the data in the PLC register is equal to a
specific number, the PLC starts a control process. Then a PLC Register Monitor is
configured for that PLC register with the Hide Data Entry attribute enabled. Now the
control process can only be started by an OIT operator who knows the correct access
number. And data entry is secured since only asterisks are shown.
To enable Hide Data Entry in a PLC Register Monitor:
1. In the Register Monitor Editor dialog box, in the Special Effects group box, select the
Hide Data Entry check box.
Blink if Bit Set
(OIT3100 and OIT4100 Series only)
This attribute will blink the PLC Register Monitor field when the PLC coil is set. It will
display the ‘off’ state continuously when the PLC coil is clear. This attribute can be used
for I/O, On/Off, or ASCII String formats.
To enable Blink if Bit Set in a PLC Register Monitor:
1. In the Register Monitor Editor dialog box, in the Special Effects group box, select the
Blink if Bit Set check box.
ASCII Text
This attribute is used to configure the two ASCII strings used to represent the state of the
specified PLC coil when using the ASCII String - PLC Coil format. It is also used to
activate the 30 ASCII strings when using ASCII String - PLC 16-bit Register format. For
information on configuring the 30 user-definable ASCII strings, refer to the ASCII String
section in this chapter.
To specify the two ASCII Strings used in ASCII String-PLC Coil format:
1. In the Register Monitor Editor dialog box, in the ASCII Text group box, select the
ASCII String number (1 to 30) for the 0 and 1 PLC coil states.
NOTE:If you need to see the user-defined ASCII strings, choose the ASCII Table button. The
ASCII Table Editor dialog box appears.
To activate the ASCII Strings in ASCII String-PLC 16-bit Register format:
1. In the Register Monitor Editor dialog box, in the ASCII Text group box, select the By
Value check box.
