Chapter 7 Parameter Overview
Sequence Step Interval
Sequencing in Matchcode operations can occur in steps from 1…32,768.
Sequencing performs like a mechanical counter by displaying positive integers
and a specific number of digits after rollovers. For example, 000-3 = 997 (not -3)
and 999+3 = 002 (not 1002). Useful in applications where it is desirable to count
by intervals other than 1.
Table 15 shows an example if your Sequence Step is set to 3 and sequential
Matching is set to Increment:
Match Replace
Outputs a user-defined data string whenever a match occurs and Matchcode is
enabled. Provides a convenient shortcut for applications that must output a
predefined text string whenever a symbol matches a master symbol.
