6.3 VIEWING AND CHANGING ACIDP AND CRDP POINTS
6.3.1 Viewing and Changing Parameter Values From the Universal Station
The current values of certain ACIDP and CRDP parameters can be viewed—and some
scheduling-related parameters can be changed—from the area Universal Station in the
Operator Personality, through the Group and Detail displays of these points. You can also
create custom Universal Station displays with similar capabilities (see the Picture Editor
Reference Manual for details).
Universal Station display and change access to ACIDP parameters is summarized in Table
6-1. US display access to CRDP parameters is summarized in Table 6-2. Brief
descriptions of these parameters—sorted by parameter name—follow at paragraph 6.4. A
more complete description of all CG parameters is found in the Computer Gateway
Parameter Reference Dictionary.
6.3.2 Viewing and Changing Parameter Values From the Host Processor
ACIDP parameter values can be obtained by the host processor through use of the "Get
ACIDP Status" request (paragraph 4.4.3). There is no equivalent access to the CRDP
parameters.
There is no mechanism for CRDP parameter change by the host processor, and ACIDP
parameter change is limited to the following:
EXECSTAT can be changed by using the "ACIDP Execution State Change" request
message (paragraph 4.4.6).
PROGSTAT can be changed by using the "ACIDP Program Mode Change" request
message (paragraph 4.4.1).
PPS can be changed by using a "Store Single Value" request message
addressed to the ACIDP (name.PPS) to store the enumeration ON (this is
used by one ACP to force another's execution).
TAKE_IP can be changed by using a "Store Single Value" request message
addressed to the ACIDP (name.TAKE_IP) to store the enumeration ON
(this is used by one ACP to tell another to take its initialization path the
next time it is turned on).
