Safety relay configuration system with multiple test pulse schemes using graphical interface

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:

• receiving first configuration input that associates a safety monitoring function block element with a configuration program for a safety relay device, wherein the safety relay device monitors an industrial safety system and controls an ability of an industrial system to run based on a status of one or more safety devices of the safety system, and the safety monitoring function block element corresponds to a safety device, of the one or more safety devices, to be monitored via an input terminal of the safety relay device;
• in response to selection, via interaction with the safety monitoring function block element, of a graphical parameter setting element of the safety monitoring function block element that facilitates selection of a test source terminal to be used as a source of a first test pulse for the input terminal, displaying a terminal selection window graphic that renders graphical indicators representing available safety relay terminals of the safety relay device, wherein the first test pulse conforms to a first test pulse scheme, and the displaying the terminal selection window comprises,
• in response to determining that one of the available safety relay terminals of the safety relay device has been assigned to be used as a source of a second test pulse conforming to a second test pulse scheme, rendering one of the graphical indicators corresponding to the one of the available safety relay terminals non-selectable via the terminal selection window graphic;
• receiving, via interaction with the terminal selection widow graphic, second configuration input selecting a graphical indicator, of the graphical indicators, representing a safety relay terminal of the available safety relay terminals;
• setting the safety relay terminal as the test source terminal for the input terminal based on the second configuration input;
• configuring a configuration program for the safety relay device based on the first configuration input and the second configuration input;
• and
• sending the configuration program to the safety relay device to facilitate programming of the safety relay device, wherein the programming of the safety relay device causes the safety relay device to output the first test pulse via the safety relay terminal.

A method for configuring an industrial safety relay, comprising:

• rendering, by a system comprising at least one processor, a safety monitoring function block representing a safety device of an industrial safety system to be monitored via an input terminal of a safety relay, wherein the safety relay monitors the industrial safety system and controls an ability of an industrial automation system to run based on a status of the safety device, and the safety monitoring function block comprises a graphical parameter setting element that facilitates selection of a test source terminal to be used as a source of a first test pulse for the input terminal, and the first test pulse accords to a first test pulse scheme;
• in response to selecting the graphical parameter setting element, displaying, by the system, a terminal selection window graphic that renders graphical icons representing available safety relay terminals of the safety relay, wherein the displaying comprises,
• in response to determining that one of the available safety relay terminals of the safety relay has been assigned to be used as a source of a second test pulse according to a second test pulse scheme, rendering one of the graphical icons corresponding to the one of the available safety relay terminals non-selectable on the terminal selection window graphic;
• receiving, by the system via interaction with the terminal selection widow graphic, configuration input selecting a graphical icon, of the graphical icons, representing a safety relay terminal of the available safety relay terminals;
• assigning, by the system, the safety relay terminal to be the test source terminal based on the configuration input;
• generating, by the system, a configuration program for the safety relay based on the configuration input;
• and
• programming, by the system, the safety relay with the configuration program, wherein the programming of the safety relay causes the safety relay to output the first test pulse via the safety relay terminal.
