6.3.6 COMMREQ Differences: Genius Bus Controllers and Genius Gateway
COMMREQs supported by the Genius Gateway (GCG) are intended to perform the same
functions as their Genius Bus Controller (GBC) counterparts. However there are four significant
differences that break compatibility with the GBC COMMREQ Command Blocks:
1.
GCG COMMREQs require a PROFINET Device Number at Address +7. This value is
required to identify which PROFINET /GCG combination is expected to process the
COMMREQ.
2.
As a result of (1) above, any COMMREQ command parameters above Address +7 are
shifted with respect to the comparable GBC COMMREQ.
3.
SYSID consists of the Rack/Slot location of the PROFINET Controller networked to the
targeted GCG rather than the Rack/Slot location of the GBC.
4.
For COMMREQs that return data to CPU memory, e.g., Read Configuration, the Memory
Offset field has been expanded from one to two words. This allows the use of bulk
memory (%W) addresses greater than 65,535. When using offsets less than or equal to
65,535, the more significant offset word must be zero.
The following table shows all Genius COMMREQs and where they are supported.
