A terminal table unit is associated with an output apparatus such as valves and solenoids and an input apparatus such as switches and includes not only a main body with a control device and a memory device but also a cassette with a memory medium that is detachably attached to the main body. The control device receives input data from the input apparatus for controlling the output apparatus and drives the output apparatus according to the received input data. The received input data are temporarily stored in the memory device in specified units. When the input data are found to include abnormal data, the control device causes data stored in the memory device to be transferred to the memory medium of the cassette such that the memory cassette can be removed and the abnormal data stored on the memory medium can be analyzed elsewhere.

Terminal table unit

A programmable controller includes a terminal which receives input data from an input unit and outputs output data to be applied to an output unit. The programmable controller also includes a communication unit which executes a serial communication with the terminal to send the output data to the output unit and to receive the input data from the input unit. A control unit repeatedly executes an input process for reading the input data received by the communication unit, an output process for sending the output data to be transmitted by the communication unit, a program execution process for executing a user program and an other process. The program execution process is executed between the input process and a subsequent output process, and the other process is executed between the output process and a subsequent input process.

Controller

A controller in which a dead space for wiring is reduced, its input-and-output response time is shortened, and miniaturization and cost reduction is ensured. A RS-232 connector connection unit (,) and a peripheral connector connection unit (,) are lowered than a projection (,) provided with displays (,to,) so that a cable connector does not exceed the projection (,) when the connector is mounted on the connector connection units (,) and (,).
