NOTE
1 Compatibility is not maintained for the interface unique to
the Series 15i.
2 The PMC–NB6 of the Series 15i is highly compatible with
the PMC–NB2 of the Series 15–B. The PMC–NB2 and
PMC–NB6 differ from each other in:
(1)Execution time–dependent ladder
As instruction execution becomes faster, the following
changes may occur in the execution timing:
S Change in the execution cycle of the second ladder
level
S Change in timing for the second–level split and
first–level execution
S Change in timing for ladder execution and I/O transfer
(2)Window functions
The functional instructions that can be used vary
between the PMC–NB2 and PMC–NB6. See Chapter 5,
”PMC Functional Instructions” in Part I, ”PMC Sequence
Program.”
(3)Screen manipulation
The operating procedure for the PMC screen for the
PMC–NB6 of the 15i varies slightly from that for the
PMC–NB2 of the 15–B.
See Chapter 7, ”PMC–NB6 Screen Manipulation,” in
Part II, ”PMC Manipulation.”
(4)Step sequence
For the PMC–NB6, the step sequence is optional.
3 The C option is necessary.
