Output Data

The process images of the module provided in the following chapters de‐
scribe the data position on the S-BUS. For information on how S-BUS proc‐
ess images are realized on the respective field bus process images, refer to
the application descriptions of the field bus couplers.
The process image is divided into two sections: One section for output data
and one section for input data. The process image can include process data
with or without diagnostic information depending on whether the transmission
of the synchronous 1) diagnostic information is enabled. This is only possible
with a field bus coupler supporting the synchronous diagnostic function (e.g.
S67-PB-BK-DI8-M8). For detailed information on the activation of diagnostic
information transfer, refer to the chapter "Device Description File" in the appli‐
cation description of the field bus couplers.
Synchronous diagnostics is disabled in the module in its delivery
state.
For detailed information, refer to
The diagnostics of the outputs "Short-circuit/overload actuator"
and "disconnection" (wire breakage) depend on the switching
state of the outputs. If the output is active, short-circuit or over‐
load can be diagnosed, but no disconnection. If the output is inac‐
tive, only a disconnection can be diagnosed.
Output data is sent from the field bus coupler to the S67-DO8-M12-2A mod‐
ule. The process image of the S67-DO8-M12-2A module can include process
data with or without diagnostic acknowledgement. If a synchronous diagnos‐
tic acknowledgement is parameterized, the process image size is 5 bytes.
Otherwise, only process data of 1 byte exists.
Process data and diagnostic acknowledgement are structured as follows:
Synchronous diagnostic information specifies the cyclic diagnostic information
1)
transfer in the process image. By default, the cyclic diagnostic information transfer
is disabled in the module.
