Programmable Safety Controller SCR P
2.5 Internal Logic
The Safety Controller's internal logic is designed so that a Safety Output can turn On only if all the controlling safety input
device signals and the Safety Controller's self-check signals are in the Run state and report that there is no fault condition.
The BERNSTEIN Safety Controller Software uses both Logic and Safety Function blocks for simple and more advanced
applications.
Logic Blocks are based on Boolean (True or False) logic laws. The following Logic Blocks are available:
•
NOT
•
AND
•
OR
•
NAND
•
NOR
•
XOR
•
Flip Flop (Set priority and Reset priority)
See
Logic Blocks
on p. 66 for more information.
Function Blocks are pre-programmed blocks with built-in logic which provide various attribute selections to serve both
common and complex application needs. The following Function Blocks are available:
•
Bypass Block
•
Enabling Device Block
•
Latch Reset Block
•
Muting Block
•
THC (Two-Hand Control) Block
•
Delay Block
See
Function Blocks
on p. 68 for more information.
2.6 Password Overview
A password is required to confirm and write the configuration to the Safety Controller and to access the Password Manager
via the Software. See and
SCR P Password Manager
2.7 SCR P-PA Programming Tool
Use the SCR P-FPS drives to store a confirmed configuration.
Important: Verify that the configuration that is being imported to the Safety Controller is the correct
configuration (via the Software or writing on the white label on the SCR P-FPS drive).
Click
to access the programming tool options:
•
Read—reads the current Safety Controller configuration from the SCR P-FPS drive and loads it to the Software
•
Write—writes a confirmed configuration from the Software to the SCR P-FPS drive
•
Lock—locks the SCR P-FPS drive preventing any configurations from being written to it (an empty drive cannot
be locked)
Note: You will not be able to unlock the SCR P-FPS drive after it has been locked.
