Apparatus and associated methods relate to generating a wiring schema with more than one safety device sharing at least one test signal through one or more external terminal blocks when the number of terminals required by safety devices exceeds the number of available terminals of a safety controller. In an illustrative example, the method may include determining a total number of terminals A of safety devices to be connected to a safety evaluation device having a number of terminals B. If A is greater than B, the method may then include generating a wiring schema that one or more external terminal blocks may show indicia of electrical connections between an identified set of safety devices and a shared terminal of the safety evaluation device associated with that set. By using the method, the number of devices that can be connected to the safety evaluation device may be expanded.
