To create a ASCII Input Extend Object
1. From the
Parts
menu, click
ASCII Input Extend
. Or click the
ASCII Input Extend
icon
in the Part1 toolbar. The Create ASCII Input Extend Object dialog box appears.
2. Use the Description: box to enter a title for the ASCII Input part. A description is not
necessary but does help you identify the purpose of the part.
3. In the Read address frame, select the PLC register or OIT internal memory address that the
part continuously reads. Select No. of words: that the part should read, (ex.1= 2 characters,
Range: 1 to 16).
4. In the Trigger address frame, select the PLC coil or OIT internal memory address that is
used to trigger write access to the register. If the coil is set, then write access is enabled. If
the coil is clear, then write access is disabled. Note: If you want the register to always have
write access, use one of the ‘always on’ internal coils of the OIT, (LB9000-9009).
5. Enter how you want the digits to be positioned in the Adjust: box. The choices are:
• Left - the OIT enters the characters into the PLC registers so that when the OIT reads the contents,
the characters are left aligned.
• Right - the OIT enters the characters into the PLC registers so that when the OIT reads the contents,
the characters are right aligned.
6. Click the Shape tab to configure a shape or bitmap that is displayed behind the number.
