NOTE
1 When 24,000 optional PMC–SB2 and PMC–SB3 ladder
steps are available, 256K bytes of the ROM module can be
used. In this case, connect the ROM module to portion 3
shown in Fig. 2.1 (a).
2 Either a RAM module, editing module, or ROM module can
be connected to each board of PMC–SA1, –SA2, –SA3,
–SB, –SB2 and –SB3.
3 Either a RAM module or ROM module can be connected to
each board of PMC–SC and PMC–SC3.
(4) Connecting the off–line programmer
Connect the off–line programmer to the reader/punch interface on the
CNC. There are several connectors for the reader/punch interface on
the CNC. The connector to be used is specified during I/O processing
