ALARM_S Messages

The STEP 7 option packages S7–PDIAG and S7–GRAPH only issue

ALARM_S messages. For that reason, the message number procedure

ALARM_S must be used for configuring process diagnosis in ProTool as well.

ALARM_S messages are not configured in ProTool but in STEP 7.

When configuring messages in STEP 7 the message text and attributes entered

are stored in the database shared with ProTool. During the process of compil-

ing the project, ProTool automatically imports the necessary data and subse-

quently downloads it to the operating unit.

Shared Database

Figure 6-5 Configuring and Downloading ALARM_S Messages

It is therefore important that the shared database is always up to date during the

compilation process and that data synchronization is active.

ALARM_S messages are configured in STEP 7. The data is then stored in a

shared database, imported during the process of compiling the ProTool project

and finally downloaded to the operating unit.

That means that ALARM_S messages use up resources on the operating unit.

The shorter the messages are, the less storage space they will require.

A maximum of 2000 event messages and 2000 alarm messages can be created.

It is of no consequence in this regard which message procedure is used.

Note

In STEP 7 there are restrictions regarding the number and size of tags that can

be used within a message. For more precise details, please consult your STEP

7 documentation.
