Parameter Declaration Data type Memory block Description
EN_R INPUT BOOL I, Q, M, D, L
Constant
Control parameter
SIG_i INPUT BOOL I, Q, M, D, L i-th signal to be monitored
ID INPUT WORD Constant
(I, Q, M, D, L)
Data channel for messages: EEEEh.
ID is only evaluated at the first call.
EV_ID INPUT DWORD Constant
(I, Q, M, D, L)
Message number (not allowed: 0)
SEVERITY INPUT WORD Constant
(I, Q, M, D, L)
Weighting of the event
DONE OUTPUT BOOL I, Q, M, D, L Status parameter DONE: Message
generation completed.
ERROR OUTPUT BOOL I, Q, M, D, L Status parameter ERROR
STATUS OUTPUT WORD I, Q, M, D, L Status parameter STATUS: Display of
an error information
ACK_STATE OUTPUT WORD I, Q, M, D, L Bit field acknowledgement status of all
8 messages
Control parameter (enabled to receive) that decides whether the output ACK_STATE is
updated (EN_R = 1) when the block is called or not (EN_R = 0).
i-th signal to be monitored It is valid 1 ≤ i ≤ 8.
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.
Bit field with the current acknowledgement status of all 8 messages.
n Bit 7 ... 0: incoming event of SIG_1 ... SIG_8
n Bit 15 ... 8: outgoing event of SIG_1 ... SIG_8
(1: Event acknowledged, 0: Event not acknowledged):
Initialization status: FFFFh, this means, all incoming and outgoing events have been
acknowledged.
