Abstract: A master unit for transmitting signals to devices connected to I/O units is divided into: a connector module having a first connector and a main module having a master processing circuit, a second connector, a branch terminal, and a power supply part. The second connector and the master processing circuit are connected by first connection terminals provided to the connector module and the main module.

Abstract: An I/O unit comprises: a plurality of first-stage-side terminals for connecting to a master unit or another I/O unit; a plurality of second-stage-side terminals that are provided in order to connect to the other I/O unit, and are connected to mutually distinct first-stage-side terminals; and a slave process circuit that performs signal processing and is connected to one of the plurality of first-stage-side terminals and to the second-stage-side terminal connected to that first-stage-side terminal.

Abstract: An I/O unit comprises: a preceding stage-side mainstream terminal and a preceding stage-side branch terminal that are connected to preceding-stage master units; a next stage-side branch terminal that is connected to the preceding-stage branch terminal and connected to another I/O unit; a slave processing circuit that is connected to the preceding stage-side branch terminal and the next stage-side branch terminal; and a next stage-side mainstream terminal connected to the preceding stage-side mainstream terminal and a master unit in the next stage.

Abstract: An I/O unit transmits signals between a master unit and instruments. The master unit has two redundant master processing circuits. The I/O unit includes: a first slave processing circuit that performs input and output of signals with respect to one of the two master processing circuits; and a second slave processing circuit that performs input and output of signals with respect to the other one of the two redundant master processing circuits.

Abstract: A master unit that transmits a signal with a device via an I/O unit comprises: a connector module having a first connector and a power source unit; and a signal processing module having a branch terminal and a master processing circuit. The connector module and the signal processing module further comprise connection terminal units that connect the first connector and the power source unit with the master processing circuit.

Abstract: The program generation apparatus includes a terminal detection unit for detecting position information including a position of a first terminal of an input/output apparatus to which an electrical wiring is connected. A display control unit displays, on a display part, a control program and position information of the first terminal detected by the terminal detection unit. The operation detection unit detects a symbol indicating the device specified by the operator. The setting unit allocates the position of the first terminal which is included in the position information of the first terminal to the symbol which is indicative of the device which has been detected by the operation detection unit.

Abstract: A plurality of modules are included by an electronic device, so as to be disposed adjacent to each other. Each of the modules includes a light emitting element configured to emit communication light toward an adjacent module disposed in one adjacent direction, and a light receiving element configured to receive communication light emitted by an adjacent module disposed in the other adjacent direction. Each of the modules disposed adjacent to each other is capable of emitting the communication light to the light receiving element of the adjacent module disposed in the one adjacent direction, and capable of receiving the communication light emitted by the light emitting element of the adjacent module disposed in the other adjacent direction.
