Design of Variables:
•
Design the data types of the variables (partic-
ularly the design of safety data types and
standard data types).
•
Define the variables that you will use in more
than one POU and variables that you will use
in only specific POUs.
•
Define the variable names for the device vari-
ables that you use to access Safety I/O Units.
•
Define the attributes of variables, such as the
Name attribute.
•
Design the variables to expose to the user
program for the standard controls.
•
Design the interface with the safety controls
of the user program for the standard controls.
Description
Determine the wiring for the communications
network, power supply, and safety I/O devices.
Description
Calculate the safety reaction times and use
them to find the safety distances.
Check to see if requirements are met. If require-
ments are not met, reconsider the designs again
starting with the system design.
Description
On the Sysmac Studio, configure the NX bus
master, Safety CPU Unit and Safety I/O Units.
Check the settings for the safety process data
communications and make any necessary
changes.
