摘要： Safety units 1d to 1f for executing a safety function processing are connected to a non-safety controller constituted by connecting a plurality of units 1b, 1c including CPU units 1a. A CPU bus 10 to be connected with the CPU units and a safety dedicated bus 11 for mutually connecting the safety units are provided to the safety units. Since the safety dedicated bus is isolated from the non-safety system, reliability of the safety function can be secured. The CPU unit can read out data through the CPU bus irrespective of the safety unit and the non-safety unit.

摘要： A network system is constructed by connecting a safety PLC constituting a master unit and safety slaves 2 to each other through a safety network 3. The safety slaves each have a device information storage unit 25 for storing individual information and status information of the safety devices connected. The individual information is acquired and stored in advance, while the stored contents of the status information are updated based on the result of monitoring the status of the safety devices in operation. These processes are executed by a MPU 23. In response to a request from the safety PLC, the device information stored are transmitted, so that the safety PLC can collect and manage the device state as well as the normal state of the slave units.

摘要： Disclosed is a proximity switch provided with an actuator unit and a sensor unit. The sensor unit is provided with an antenna coil, a transmitting circuit which transmits electromagnetic waves at a constant frequency to the antenna coil, a receiving circuit which detects external signals received by means of the antenna coil, and control circuits. The actuator unit is provided with an antenna coil, a power supply circuit which rectifies an electromotive force generated in the antenna coil, and a signal processing circuit which receives power supply from the power supply circuit, performs frequency-dividing to the signals received by means of the antenna coil, and transmits the signals from the antenna coil after the frequency-dividing. The control circuit of the sensor unit has memory for registering the frequency of the signals transmitted from the actuator unit. The control circuit determines whether the actuator unit is in proximity to the sensor unit or not by checking the received signals detected by means of the receiving circuit with the operations of the transmitting circuit and the frequency registered in the memory.

摘要： A safety controller provides a safety output to a target controlled system such as a magnet contactor based on an input from an input device such as a safety door switch to thereby control operation of machine equipment. Safety output parts serve to transmit a solid-state output as the safety output and a connection output part transmits a connection output to another safety controller. A control part having two CPUs controls the safety output and the connection output according to a program based on the input from the input device. Two or more of such safety controllers are connected through their connecting output parts and the connecting input parts to together form a safety system.
