Programmable Coprocessor Module
restrictions
PACSystems RX7i CPUs with firmware versions 1.50 or later support
IC697PCM711 modules with firmware versions 4.05 or later. You must
ensure that you are using the correct firmware version of the PCM
because the CPU cannot check the PCM’s firmware version. (The
module’s firmware version can be found on a label attached to the
EEPROM.)
PACSystems does not support the following for IC697PCM711:
Connecting Machine Edition to the CPU through the
IC697PCM711 module’s serial ports.
Access to Symbolic variables.
WAIT mode COMMREQs.
The following C functions are not supported:
chk_genius_bus
chk_genius_device
get_cpu_type_rev
get_memtype_sizes
get_one_rackfault
get_rack_slot_faults
The C function write_dev will not write to read only reference
tables (%S references, transition bits, and override bits). If this is
attempted, the call will fail at run time and return an error code.
The following restrictions apply when using the IC697PCM711 with
PACSystems:
%W memory partially supported. Only offsets 0-65535 of %W can be
accessed via the PCM.
The Program Name is currently always LDPROG1 for
PACSystems.
In case of ERROR NACK, the Control Program number, privilege
level and other piggyback status data will be set to 0.
If an application program running on the PCM accesses the VME
bus, the VME addresses being used by that program must be
updated to agree with the PACSystems RX7i VME addressing
assignments. PACSystems RX7i VME address assignments are
described in the PACSystems RX7i User’s Guide to Integration of
VME Modules, GFK-2235.
PACSystems CPUs return the major/minor type of the Series 90-
70 CPX935 (major type 12, minor type 35) to the PCM scratch
pad memory when communicating with a PCM.
If your RX7i application program needs to access the PCM’s dual
port memory, use the BUS READ and WRITE functions. When
accessing the PCM, set the Region parameter on the function
block to 1. (For the PCM, region 1 is predefined to be the
module's entire dual port memory.)
Note: For details on operation of the IC697PCM711, refer to the
Programmable Coprocessor Module and Support Software
User’s Manual, GFK-0255.
