ASCII String - PLC Coil
This format is used to represent a single coil in the PLC as a binary value with
user-definable strings that indicate whether the coil is on or off. Two ASCII strings can
be created to represent the PLC coil. For example, RUNNING to represent the ‘on’ state
and STOPPED to represent the ‘off’ state. In OITware, enter the strings to be displayed
using the ASCII Table Editor. Up to 30 strings may be entered, each up to 16 characters
in length. Then, in the ASCII Text box of the Register Monitor Editor in OITware,
assign a string number to the off or ‘0’ state and to the on or ‘1’ state.
This format can also be used to represent a data register in the PLC. Select the ASCII
String format, then check the ‘By Value’ box in the ASCII Text box of the Register
Monitor Editor in OITware. String #1 in the ASCII Table Editor will correspond to data
value ‘0’, string #2 to data value ‘1’, etc. If the data value is larger than 29, then string
#30 will be displayed.

To configure the 30 ASCII strings:
1. From the Configuration menu, choose ASCII Table Editor or in the Register Monitor
Editor, choose the ASCII Table button. The ASCII Table Editor dialog box appears.
2. Enter the text for each string you want to configure.
NOTE:To delete all existing strings, choose the garbage can button. To insert characters from
the extended character set, from the Insert menu, choose Special Character. The Insert
Special Characters dialog box appears. For instructions on using this dialog box, refer to
the Special Characters section in CHAPTER 3: Stored Screens.
3. Choose the Done button to return to the OITware-200 main screen or the Register
Monitor Editor.
ASCII String - PLC 16-bit Register
(OIT3100 and OIT4100 Series only)
This format is used to represent 16-bit data registers in the PLC with user-definable strings.
A maximum of 30 ASCII strings, each up to 16 characters in length, can be programmed
into the OIT. When the value in the PLC data register is from 0 to 29 the corresponding
ASCII string is displayed (PLC value 0 = ASCII string 1; PLC value 1 = ASCII string 2,
etc.). If the value in the PLC data register does not have a corresponding ASCII string, then
the OIT displays a blank string. Each PLC Register Monitor using the ASCII String format
can use any of the 30 strings. The length (Number of Digits) of the PLC Register Monitor
should be set to match the longest of the selected ASCII strings.
