Safety relay configuration system with safety monitoring and safety output function blocks

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 a graphical safety monitoring function block element corresponding to a safety device to be monitored via at least two input terminals of the safety relay;
• rendering at least two input reference container graphics in association with the safety monitoring function block element, the at least two input reference container graphics corresponding to respective channels of a multi-channel safety monitoring system;
• receiving configuration input via interaction with the safety monitoring function block element, wherein the receiving comprises:
• receiving, as at least a first portion of the configuration input via first and second interactions with respective two of the at least two input reference container graphics, terminal identification data identifying a first selected input terminal of the at least two input terminals and a second selected input terminal of the at least two input terminals, wherein at least one of the first selected input terminal or the second selected input terminal is a multi-purpose terminal of the safety relay;
• and
• generating a configuration program for the safety relay based on the configuration input, wherein the generating the configuration program comprises configuring the configuration program to
• associate the first selected input terminal and the second selected input terminal with the safety monitoring function block element,
• in response to determining that the safety monitoring function block element is a single-wire safety function block, configure the multi-purpose terminal as a single-wire safety input, and
• in response to determining that the safety monitoring function block element is associated with a safety input device, configure the multi-purpose terminal as a normally closed safety-rated input.

A method for configuring a safety relay program, comprising:

• rendering, by a system comprising at least one processor, a graphical safety input function block element;
• rendering, by the system, at least two input reference container graphics in association with the safety monitoring function block element, the at least two input reference container graphics corresponding to respective channels of a multi-channel safety monitoring system;
• receiving, by the system, configuration input via interaction with the safety monitoring function block element, wherein the receiving comprises
• receiving, as at least a first portion of the configuration input via first and second interactions with respective two of the at least two input reference container graphics, terminal identification data identifying a first selected input terminal of the at least two input terminals and a second selected input terminal of the at least two input terminals, wherein at least one of the first selected input terminal and the second selected input terminal is a multi-purpose terminal of the safety relay;
• and
• generating, by the system, a configuration program for a safety relay based on the configuration input, wherein the generating the configuration program comprises configuring the configuration program to
• associate the first selected input terminal and the second selected input terminal with the safety monitoring function block element,
• in response to determining that the safety monitoring function block element is a single-wire safety function block, configure the multi-purpose terminal as a single-wire safety input, and
• in response to determining that the safety monitoring function block element is associated with a safety input device, configure the multi-purpose terminal as a normally closed safety-rated input.
