Notes: Double clicking on a current Register Monitor (or pressing the Register Monitor Editor
button with the monitor highlighted) enables you to edit an existing Register Monitor.
Example Group Box
This box contains a sample of what the data on the message will look like. Refer back to this
box when making changes to examine how the register monitor will look on the message
when you are finished. The register monitor will occupy the same number of characters on
the message when you click on the Add button. Nothing within the Example box may be
changed; it is for reference only.
Data Group Box
This is the box where you specify the actual PLC register information, the PLC register type,
the address, the sub-element and the format. Depending on the type of PLC selected,
additional information may appear in this box. In the example above, the Allen-Bradley PLC
has been selected. In this particular case, the PLC register type, address, and sub-element are
used to specify a coil within the PLC.
Format
The following formats can be selected in the Format box:
• Signed—This format is used to represent a 16-bit register in the PLC as a signed integer
value with a range of -32,768 to +32,767.
• Decimal—This format is used to represent a 16-bit register in the PLC as an unsigned
integer value with a range of 0 to 65,535.
• Long—This format is used to represent a 32-bit register in the PLC as a signed long
integer value with a range of -2,147,483,648 to +2,147,483,647.
• 4-Digit BCD—This format is used to represent a 16-bit register in the PLC as a BCD
value with a range of 0 to 9,999. If the value in the PLC register is not in BCD format, then
the OIT will display the value as hexadecimal.
• 8-Digit BCD—This format is used to represent a 32-bit register in the PLC as a BCD
value with a range of 0 to 99,999,999. If the value in the PLC register is not in BCD format,
then the OIT will display the value as hexadecimal.
• 1/0 Coil—This format is used to represent a single coil in the PLC as a binary value with
‘0’ indicating the coil is off and ‘1’ indicating that the coil is on.
• On/Off Coil—This format is used to represent a single coil in the PLC as a binary value
with ‘Off’ indicating the coil is off and ‘On’ indicating that the coil is on.
• Bank 8—This format is used to represent eight consecutive coils in the PLC as binary
values with ‘0’ indicating that the coil is off and ‘1’ indicating that the coil is on. The
highest addressed coil is always displayed in the left-most position.
• Bank 16—This format is used to represent 16 consecutive coils in the PLC as binary
values with ‘0’ indicating that the coil is off and ‘1’ indicating that the coil is on. The
highest addressed coil is always displayed in the left-most position.
• ASCII Char—This format is used to represent a 16-bit register in the PLC as a
corresponding ASCII character. If the Number of Digits Attribute is set to 2, then the OIT
will read the 16-bit register as two 8-bit ASCII characters and display them. If the Number
of Digits Attribute is set to 1, then the OIT will read the lowest eight bits of the 16-bit
register and display one ASCII character. If the value in the PLC register does not
