IP21 Source System: Server Settings Tab

Prerequisites

In the Plant Connectivity Management Console and the IP21 database, you need a Windows user with the appropriate authorizations.
The IP21 agent uses the IP21 DBApi interface of the IP21 database. You therefore need to copy the following files of the IP21 installation to the PCo system directory, for example, c:\Program Files\SAP\Plant Connectivity\System:
- cimsrvapi.dll
- CimWin32Util.dll
- infoplus21_api.dll
- ip21admin_client.dll
- ip21ezrpcw32.dll
- ip21winrpc32.dll
- libc21.dll
The following fields must exist in the tag definition in the IP21 source system in order for the IP21 agent to function:
- IP_VALUE (value of tag)
- IP_VALUE_TIME (time of value change)
- IP_VALUE_QUALITY (quality of tag)
- IP_#_OF_TREND_VALUES (number of historic values)
- IP_TREND_VALUE (historic value)
- IP_TREND_QSTATUS (quality of historic value)
- IP_TREND_QLEVEL (expected value of quality)
- IP_DESCRIPTION (description)
- IP_GRAPH_MINIMUM (minimum value)
- IP_GRAPH_MAXIMUM (maximum value)

Procedure

You define the settings for the IP21 database here. (See also IP21 Source System.)

Field	Description
Server	Here you enter the server on which the IP21 database is installed.
Use Long Record Name, If Possible	By choosing this indicator, you define how you want the IP21 records to be read. If you set the indicator, the long record names are read. Until IP21 Version 7.3 the record names of the tags were maximum 24 characters long. As of IP21 Version 7.3 the record names can be up to 256 characters long. New methods have been introduced by IP21 for reading the new (long) record names. With the old methods, only records with 24 characters can be read. With the new methods, all records can now be read. To make sure that the new methods are used, you need to set the indicator.

By choosing this indicator, you define how you want the IP21 records to be read. If you set the indicator, the long record names are read.

Until IP21 Version 7.3 the record names of the tags were maximum 24 characters long. As of IP21 Version 7.3 the record names can be up to 256 characters long.

To make sure that the new methods are used, you need to set the indicator.

Result

You can now define an alias. The following fields of the IP21 source system can be read as metadata by PCo when an alias is created:

IP_DESCRIPTION
IP_GRAPH_MINIMUM
IP_GRAPH_MAXIMUM

All other fields of a selected tag are read as secondary elements.
