Parameter settings in the follower FSOs
Index Name/Value Description
SAFEIO.11 M/F mode for
cascade
Sets the master/follower mode of the FSO module for both
cascade connection A and B separately. In this example, only
cascade connection A is used.
A = follower,
B = follower
This module is a follower on cascade connection A.
SAFEIO.12 Cascade A Sets the cascade connection A for the FSO module. For each
FSO module in cascade A, the digital input connected to the
safety function is also internally connected to the corresponding
digital output of the module (digital input -> digital output).
X113:2 ->
X113:8
Single cascade X113:2 -> X113:8
STO.02 STO
acknowledge
ment
Sets the acknowledgement method used in the STO, SSE and
SS1 functions.
Automatic The FSO module generates the STO acknowledgement signal
automatically after the STO, SSE or SS1 request has been
removed and the stop function is completed (output defined by
parameter FSOGEN.11 Stop completed output is active).
SSE.11 SSE input A Sets the digital input that is connected to the primary input of the
SSE function.
In this example, the activation of the SSE function in the follower
FSOs comes from the master FSO through the cascade loop
(Cascade A), and this parameter must be set to None.
None No input connected
SSE.12 SSE input B Sets the digital input that is connected to the secondary input of
the SSE function.
In this example, this parameter sets the digital input that is used
in the cascade loop (Cascade A) to cascade the SSE function to
the follower FSOs.
DI X113:2 Single input X113:2
SSE.21 SSE output Sets the digital output that indicates the activity of the SSE
function. Active from the SSE request until the function has been
acknowledged.
In this example, this parameter sets the digital output that is used
in the cascade loop (Cascade A) to cascade the SSE function to
the follower FSOs.
DO X113:8 Single output X113:8
SSE.22 SSE
completed
output
Sets the digital output that indicates the completion of the SSE
function.
None No output connected
