Note
1.
The DCP address is a three-byte address containing a drum number in the
most significant 20 bits and a step number in the least significant 4 bits.
Note 2.
These flags have a “control” part and a “status” part. When written, only
the control part is written. When read, the status part is returned with the control
part set to zero.
Note 3.
This data element is an Analog Alarm type.
Note 4.
VMS corresponds to VME address modifier 29 (short non-privileged access).
VMM corresponds to VME address modifier 39 (standard non-privileged data
access.) The access size is always 16 bits. The offset field contains the relative word
of the specified address space.
Note 5.
Each PLC in a 575 system may contain one or more application process.
These applications are identified by a single letter ranging from Application A
through Application Z. Associated with each application is a G Memory partition.
Access to the G memory partitions (in the 575 PLC) associated with a PLC
application is provided through plcTT D5 through EE (hex). Addressing (plcTT
offset) of these partitions is 24-bit zero relative.
Note 6.
The G memory partitions (in the 575 PLC) are global memories accessible
by the local PLC as well as by other bus masters. Access to the G memory partition
associated with the local PLC is provided through plcTT EF (hex). The addressing of
this partition is 24-bit zero relative; (that is, the first element of G memory is G1,
which has an offset of 0).
