16.2.2.3 How to Configure PCS 7 Messages (Project-Oriented)
For editing message types and messages to be output on WinCC display devices, the PCS7
message configuration function in STEP 7 provides a user-friendly method of:
• Simplifying the configuration of display devices (created automatically)
• Simplifying the entry of attributes and texts for messages
• Ensuring that messages are standardized.
Opening the PCS7 Message Configuration Function
1. In the SIMATIC Manager, select the block (FB or DB) whose message texts you want to edit.
Select the menu command Edit > Object Properties to open the dialog box for entering
system attributes.
2. In the table shown, enter the system attribute "S7_alarm_ui" and the value: "1" (the value 0
disables the PCS7 message configuration tool). Property parameters can be set in
LAD/STL/FBD. DBs generated afterwards and assigned to the corresponding FBs take on
these attributes and can be switched independently of their message type (FB).
Note: A syntax check is performed when you enter the system attributes. Faulty entries are
highlighted in red.
3. Exit the dialog box with "OK."
4. Select the menu command Edit > Special Object Properties > Message
Result: The "PCS7 Message Configuration" dialog box is opened.
Editing Message Types
1. In the SIMATIC Manager, select the FB whose message texts you want to edit, and open the
PCS7 message configuration dialog box.
Result: The dialog box displays a tab for each message block for which you declared a
variable in the FB.
2. Fill out the text boxes for the message components "Origin," "OS area," and "Batch ID."
3. Enter the message class and the event text for all events of the message blocks used and
specify whether every event must be acknowledged individually.
4. For the message parts that apply for all instances and should not be changed, select the
"Locked" check box.
Editing Messages
1. Open SIMATIC Manager. Select the instance DB whose message texts you want to edit and
open PCS7 message configuration function.
2. Do not edit instance-specific message parts that are not locked.
