A.3
Compiling a CDS does not set aside storage for the parameter values; it simply defines the
parameters to the system. The next required step is to build a point that uses the CDS
parameters. Once a data point is built, the parameters of the CDS are part of the data point
and are undifferentiated from other parameters of the data point.
At this point, you should back up the .SE and .SP files on &ASY and should also
checkpoint the CG.
A.3 ACIDP/CRDP POINT BUILDING
CG point data can be recorded on Form CG88-500 in preparation for the actual point-
configuration process. Explanation of the entries is found in the Computer Gateway
Parameter Reference Dictionary and the point-entry process is described in the Data Entity
Builder Manual.
A brief outline of ACIDP/CRDP building follows:
1. From the Engineering Personality Main Menu, select the
COMPUTING MODULE target
in the Point Building column. This calls up the CM BUILD AND CONFIGURATION
MENU.
2. Select the target appropriate to the point type to be built.
3. Enter the desired information into the CM ACIDP/CRDP POINT ASSIGNMENT display;
save the point data in an IDF and then load the point.
If the point is a CRDP, it should have at least one associated "package," i.e., a CDS. For
an ACIDP, any CDS is optional.
A.3.1 ACIDP Scheduling Recommendations
Set long RTPERIOD values for cyclic and periodic ACPs or set them to demand-only and
determine how long they actually run before selecting the normal running period.
If the RTPERIOD in an ACIDP is short (close to the time required for the associated ACP
to execute), it will be difficult or impossible to disconnect the ACIDP or to uninstall the
ACP. If this happens, change the parameter INH_STAT to INHIBIT from the point's
Detail Display at a Universal Station. Wait for the ACP to terminate as indicated by a
change of Execution State to DELAY, then disconnect the ACP from the ACIDP.
