Abstract: The present invention provides a mechanism for adding a disabling function that satisfies a safety standard to a safety program in a simplified procedure. A program creation assistance device that assists in creation of a safety program to be executed by a safety controller creates a safety program including an input block to which a safety input signal from an input device is assigned, a functional block that implements a safety function, and an output block that outputs a safety output signal, and adds, to the safety program created, a plurality blocks and connections between the plurality of blocks in accordance with an instruction from a user, the plurality of blocks and the connections between the plurality of blocks being configured to implement a disabling function that disables the safety input signal when a predetermined condition is satisfied in the safety program.

Abstract: To monitor individual safety components or to supply individual operation instructions to corresponding safety components. A connector includes a component-side terminal group used for connection to a corresponding safety component, a downstream-side terminal group used for connection to the downstream side and an upstream-side terminal group used for connection to the upstream side. The downstream-side terminal group includes a downstream-side main information terminal connected to the component-side main information terminal and a downstream-side other terminal different from the downstream-side main information terminal. The upstream-side terminal group includes an upstream-side information terminal capable of being connected to a downstream-side main information terminal of a connector member on the upstream side.
