Response of an already activated
monitoring function using local
disconnection for acceleration
processing
• Observe the note at the end of this
table
84 For a monitoring function that has already been
activated via PROFIsafe, the DCS21B option
needs two cycles to calculate the current
acceleration value. During the next cycle, the result
is entered in the system image once the monitoring
function was calculated. If local disconnection
has been activated (available in the DCS21B
option), a programmed output is operated within
the same cycle, if required.
Note: When using local disconnection and
ENABLE via the bus system, the specified time
is the relevant response time.
Response of an already activated
monitoring function including
transmission to PROFIsafe for position
and speed processing
112 For a monitoring function that has already been
activated via PROFIsafe, the DCS21B option
needs one cycle to calculate the current speed
value. During the next cycle, the result is entered in
the system image once the monitoring function was
calculated. Two more cycles are required for
sending the result to the safety controller via
PROFIsafe.
Response of an already activated
monitoring function including
transmission to PROFIsafe for
acceleration processing
140 For a monitoring function that has already been
activated via PROFIsafe, the DCS21B option
needs two cycles to calculate the current
acceleration value. During the next cycle, the result
is entered in the system image once the monitoring
function was calculated. Two more cycles are
required for sending the result to the safety
controller via PROFIsafe.
Activation of an ENABLE input of a
monitoring function for transmission
via PROFIsafe
56 Two cycles are required to transfer information from
the PROFIsafe input telegram and to enter it in the
process image.
Activation of an output for transfer via
PROFIsafe
56 Two cycles are required for reading off output
information from the PROFIsafe input telegram and
for entry in the process image. After the information
has been entered in the process image, the output
is enabled/disabled within the same cycle.

Explanation
INFORMATION
If local switch-off is used with SS1 deceleration time, the outputs remain switched until
the time has elapsed. Take this fact into account in the risk assessment.
