Parameter Declaration Data type Memory block Description
STATUS OUTPUT WORD I, Q, M, D, L STATUS parameter:
Display of an error information
ACK_DN OUTPUT BOOL I, Q, M, D, L Outgoing event was acknowledged
ACK_UP OUTPUT BOOL I, Q, M, D, L Incoming event was acknowledged.
SD_i IN_OUT ANY I, Q, M, D, T, C i-th associated value
Control parameter (enabled to receive) that decides whether the outputs ACK_UP and
ACK_DN are updated at the first block call (EN_R = 1) or not (EN_R = 0). If EN_R = 0 the
output parameters ACK_UP and ACK_DN remain unchanged.
The signal to be monitored.
Data channel for messages: EEEEh. ID is only evaluated at the first call.
EV_ID is only evaluated at the first call. Subsequently, the message number used for the
first call applies to every call of SFB with the corresponding instance DB. The message
number is automatically assigned by the Siemens STEP
®
7 programming tool. So the con-
sistency of the message numbers is guaranteed. The message numbers within a user
program must be unique.
Weighting of the event Here the value 0 is the highest weighting. This parameter is irrele-
vant for processing the message. Possible values: 0 ... 127 (default value: 64)
Status parameter DONE, Message generation completed.
Outgoing event has been acknowledged on a display device. Initialization status: 1. The
ACK_DN output is reset at the negative edge. It is set when your acknowledgement of
the event leaving the state is received from a logged on display device.
Incoming event has been acknowledged on a display device. Initialization status: 1 The
ACK_UP output is reset at the rising edge. It is set when your acknowledgement of the
event entering the state has arrived from a logged on display device.
i-th associated value It is valid 1 ≤ i ≤ maxNumber. The max. number of associated values
may be found in the technical data of your CPU. Permitted are only data of the type
BOOL, (not permitted: bit field), BYTE, CHAR, WORD, INT, DWORD, DINT, REAL,
DATE, TOD, TIME, S5TIME, DATE_AND _TIME.
When the ANY pointer accesses a DB, the DB always must be specified.
(e.g.: P# DB10.DBX5.0 Byte 10).
