Standard Function Blocks
Modular Block System: Emergency Stop Circuits
SB062 E-STOP
SB062 is used in applications up to category 4. This standard function
block is suitable for applications with SafetyBUS p. It has an input
parameter to evaluate the status of the I/O-Group (SafetyBUS p), for which
parameters are set on the E-STOP button contacts.
The run time for SB062 in comparison with SB061 has been optimised so
that SB062 is suitable for use in time-critical or very extensive applications
(even without SafetyBUS p).
It is possible to monitor whether contacts switch synchronously when
releasing an E-STOP button that has been operated. SB062 provides an
additional input parameter for this task.
The additional commands for monitoring the SSNR are not required.
SB063 E-STOP
SB063 is used in applications up to category 4. The function range of
SB063 corresponds largely to that of SB062. However, the value range for
the safety subroutine number SSNR has been expanded to 1...600 (see
Chapter 5, section entitled “Input parameter SSNR”).
The use of SB063 is preferred in very extensive applications (> 200
standard function blocks). In this case, a fast PSS-CPU (e.g. CPU 3) is
also preferable.
The additional commands for monitoring the SSNR are not required.
