Standard Function Blocks
Modular Block System: Hydraulic Presses
It is possible to monitor whether contacts switch synchronously when
releasing an E-STOP button that has been operated. SB063 provides an
additional input parameter for this task.
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.
Safety gate monitoring
SB066 ST_K4
SB066 is used in applications up to category 4. This standard function
block has no parameter to evaluate the status of I/O-Groups
(SafetyBUS p).
INFORMATION
Do not use SB066 in applications with SafetyBUS p.
