Configuration notes:
In contrast to the bit alarm procedure, Alarm_S messages are based on the alarm-numbering procedure. As a general rule, Alarm_S messages are not configured in WinCC flexible. They are only ever configured or programmed in STEP 7 or in SIMOTION Scout. The advantage of this is that the alarm texts can be used on a variety of display devices, but only need to be entered once.

When messages are configured in STEP 7 or SIMOTION, you can either enter simple alarm texts without any further formatting or also make use of the possibilities of device-specific message configuration. Depending on the type of display device being used, you can also display flashing text, for instance, and configure additional info text.

Requirements:

• SIMOTION Scout Project
• WinCC flexible ES + RT (from WinCC flexible 2005)
• STEP 7 project with an integrated HMI and SIMOTION station

Note:
There are only some versions of SIMOTION Scout software which are compatible with or released for use with WinCC flexible 2005. These versions are specified in Entry ID 22055368.

Configuring Alarm_S messages in SIMOTION SCOUT
 

No.	Procedure
1	Adding Alarm_S messages Open the alarm-configuration editor in SIMOTION Scout via "Target system > Configure messages". Mark "Alarm_S" in the top left of the dialog box. Click the "New" button to insert an Alarm_S message. Fig. 01
2	Inserting the symbol, alarm text and format string Assign a symbol to the Alarm_S message. The symbolic name is required in order to trigger the Alarm_S message via the ST program. Insert your alarm text. If you enter the following format string into the alarm text, you can also assign a process value to the message as an associated value. Composition of the format string: @[Pvn][Type]%width[.precision]format@ Symbol Meaning Value range Default @ Start of the format string - - Pvn Process value number (optional) 1-4 1 Type Type of process value (optional) See Table 02 I %width Width of the display field on the HMI device - - .precision Number of places after the decimal point (optional in format = "f" ) - - format Process value display mode See Table 03 - @ End of the format string - - Table 01 - Composition of the associated values Permissible values for "type":   Type Meaning "b" or "B"  BOOL "y" or "Y" BYTE "c" or "C" CHARACTER "w" or "W" WORD "i" or "I" INTEGER "x" or "X" DWORD "d" or "D" DINT "r" or "R" REAL Table 02 - Type Permissible values for "format":   format Display "d" decimal with a sign "u" decimal without a sign "X" hexadecimal "f" fixed point number with a sign "b" binary "s" ANSI string Table 03 - Format
3	Configuring Alarm_S messages Select the type of message, i.e. "Fault messages" or "Operating messages". Assign as Alarm_S display class to the message. Fig. 02 Note: The "Printout (at HMI)" selection field allows you to log the messages in WinCC flexible Runtime.

Triggering the Alarm_S message by calling the _alarmS (message not requiring acknowledgment) and _alarmSq (message requiring acknowledgment) system functions
 

No.	Procedure
1	Adding system functions Add an ST program unit. Declare global variables and a program structure in the interface part. Add the call for the "_alarmS" or "_alarmSq" system function in the part of the program. Parameters for the "_alarmS" and "_alarmSq" system function: Return value (DWORD):= _alarmS (alarm signal (BOOL), Alarm_S symbol, associated value); Fig. 03
2	Inserting a program in the runtime system Insert the program into the background task in the CPU's runtime system.

Displaying Alarm_S messages and TO alarms in WinCC flexible Runtime
 

No.	Procedure
1	Activating Alarm_S messages Open the "Alarm Management > Settings > Alarm Settings" dialog box. Select the display classes in the "ALARM_S" column under "Alarm procedures" and enable the display of TO alarms in the "SIMOTION TO" column. Fig. 04   Alarm procedure Application Alarm_S User-definable messages SIMOTION TO (technological alarm) System messages from the SIMOTION controller Table 04
2	Activating the alarm class in the alarm display Open a picture in WinCC flexible ES. Insert an alarm display. The alarm classes "S7 message" and "S7 warning" are available in the alarm display for the purposes of displaying Alarm_S messages and TO alarms. With "S7 message"-class alarms, Alarm_S messages and TO alarms which need to be acknowledged are displayed. With "S7 warning"-class alarms, Alarm_S messages and TO alarms which do not need to be acknowledged are displayed. Fig. 05
