Development environment for a safety relay configuration system

A non-transitory computer-readable medium having stored thereon instructions that, in response to execution, cause a system comprising a processor to perform operations, the operations comprising:

• rendering, by a graphical interface component implemented by the processor, a safety logic editor display comprising four columns of blank function targets for placement of graphical function block elements, the graphical interface component enforcing association of designated types of graphical function block elements to respective columns of the four columns, the four columns comprising
• a first column designated for placement of safety monitoring function block elements corresponding to respective safety input devices,
• a second column designated for placement of AND, OR, or pass through logical operator function block elements,
• a third column designated for placement of AND, OR, or pass through logical operator function block elements, and
• a fourth column designated for placement of safety output function block elements corresponding to respective safety outputs of the safety relay;
• receiving, via the safety logic editor display, first configuration input that associates graphical function block elements with respective blank function targets of the four columns of blank function targets;
• programmatically associating, by a configuration component implemented by the processor, an output of a first function block element of the graphical function block elements with an input of a second function block element of the graphical function block elements in response to receipt of second configuration input that sets a reference parameter located on the second function block to an identifier of the first function block;
• and
• creating, by the configuration component, a configuration program for a safety relay based on the first configuration input and the second configuration input.

A method for configuring an industrial safety system, comprising:

• displaying, by a system comprising at least one processor, a safety logic editing window comprising an array of blank function targets for placement of graphical function block elements, wherein the safety logic editing window enforces association of designated types of graphical function block elements to respective columns of the four columns, the four columns comprising
• a first column designated for placement of safety monitoring function blocks elements corresponding to respective safety input devices,
• a second column designated for placement of AND, OR, or pass through logical operator function block elements,
• a third column designated for placement of AND, OR, or pass through logical operator function block elements, and
• a fourth column designated for placement of safety output function block elements corresponding to respective safety outputs of the safety relay;
• receiving, by the system via the safety logic editing window, first configuration input that associates graphical function block elements with respective blank function targets of the four columns of blank function targets;
• programmatically associating, by the system, an output of a first function block element of the graphical function block elements with an input of a second function block element of the graphical function block elements in response to receipt of second configuration input that sets a reference parameter located on the second function block element to an identifier of the first function block element;
• and
• creating, by the system, a configuration program for a safety relay based on the first configuration input and the second configuration input.
