Abstract
The present invention provides a mechanism for causing a safety controller to suitably display various pieces of information from a safety input device. A safety controller acquires a compatible port that connects at least one safety input device, and a safety input signal from the at least one safety input device connected via the compatible port and state information on the safety input device. Further, the safety controller 3 includes the MCU 23 that generates, in accordance with the safety program, a safety output signal based on the safety input signal acquired, and the display device 5a that displays, based on the state information acquired, a state of the safety input device from which the state information is acquired.
Claims19
A safety controller that executes a safety program, the safety controller comprising:
- a port connector including a communication line detachably connected to at least one first safety input device;
- an IO connector including an ON/OFF input terminal detachably connected to at least one second safety input device;
- an acquisition unit that acquires a first safety input signal and state information from the at least one first safety input device connected via the port connector, and acquires a second safety input signal from the at least one second safety input device connected via the ON/OFF input terminal;
- an execution engine that generates, in accordance with the safety program transmitted as a user created program from an external device, a safety output signal based on the first safety input signal and the second safety input signal acquired by the acquisition unit;
- and
- a display unit that displays, based on the state information acquired over the communication line by the acquisition unit, a state of the safety input device from which the state information is acquired.
