YASKAWA VIPA SPEED7 - SFB 36 - NOTIFY - Messages Without Acknowledgement Display

14.2.16 SFB 36 - NOTIFY - Messages without acknowledgement display
Generating block-related messages without acknowledgement display.
n SFB 36 NOTIFY monitors a signal. It generates a message both on a rising edge
(event entering state) and on a falling edge (event leaving state) with associated
values.
n When the SFB is first called, a message with the current signal state is sent. The
message is sent to all stations logged on for this purpose.
n The associated values are queried when the edge is detected and assigned to the
message.
Parameter Declaration Data type Memory block Description
SIG INPUT BOOL I, Q, M, D, L The signal to be monitored.

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.
