7.2.3 Interface Between CNC and PMC
The PMC to control the interface between the CNC and PMC and
PMC addresses (F/G addresses) can be set with CNC parameters.
With these parameter settings, a desired interface control system can
be built, in which the entire CNC-PMC interface of the CNC may be
controlled by a single PMC or the CNC-PMC interface may be
controlled by multiple PMCs.
For the CNC-PMC interface, a memory area consisting of 10 blocks,
each of which is an addressable, 768-byte DI/DO area, is provided.
When viewed from the ladder program in each PMC, these addresses
begin with 0.
If these parameters are not set (0 is set), the initial settings are
assumed, where the F/G addresses of the CNC equals the F/G
addresses of the first PMC as follows:
