摘要： PROBLEM TO BE SOLVED: To easily prepare a safety program, and to attain authentication procedures to the safety program.
SOLUTION: In a step 435, the slot selection lamp of an I/O module connected to the next slot is turned on, and a user is informed that the ID number of the module should be input, and the ID number of the I/O module is input. In a step 440, the confirming operation of the I/O module is accepted. In the next step 445, when the ID number input from the user is matched with the ID number owned by the actual I/O module, the slot selection lamp of the module is turned off, and the processing is shifted to a step 450, and in the other case, the error lamp of the module is turned on, and the processing is shifted to a step 490. In the step 450, the ID number of the I/O module whose matching has been confirmed is stored.

摘要： PROBLEM TO BE SOLVED: To shorten the detection time and the interrupting time as compared with a conventional monitor by performing the monitoring through analysis or comparison of motor current or voltage of a driver. SOLUTION: An AC voltage obtained from a transformer 10, 12, 14 is rectified through a rectifier 16, 18, 20 and fed through a preresistor to each IGBT transistor constituting an electronic load relay where the AC voltage is applied between the gate and the emitter. When an external interruption signal is applied to an optical coupler 34, 36, 38, the gate-emitter of the output transistor is short-circuited and the IGBT transistor is interrupted. When a semiconductor channel is interrupted or short-circuited during operation, the failure is analyzed and recognized by an electronic monitor and a motor M is interrupted instantaneously.

摘要： PROBLEM TO BE SOLVED: To raise the frequency of a digital signal to be transmitted on a signal transfer path in a safety PLC higher than that in a conventional way concerning the safety PLC having duplexed power supply circuits. SOLUTION: A system A (a circuit 201) and a system B (a circuit 202) are connected with a signal transfer path L having an MELF resistor R 1 and perform communication via the signal transfer path L. A DC output voltage B_Vcc is normally applied to a point p B . By the above configuration, even when a fault such as short-circuiting occurs in a DC power supply device for supplying the DC output voltage B_Vcc, the DC output voltage B_Vcc of the DC power supply device is not more than 4.0V. Consequently, the resistor value of the MELF resistor R 1 is set down to 2 kΩ even when the rated current of an operation circuit arranged in the system A is 2 mA. Thus, a parasitic capacity constituting a low-pass filter is effectively eliminated from the signal transfer path L. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提高在安全PLC中的信号传递路径上传输的数字信号的频率高于关于具有双工电源电路的安全PLC的传统方式的频率。解决方案：系统A（电路201）和系统B（电路202）与具有MELF电阻器R 1 的信号传输路径L连接，并通过信号传输进行通信路径L.通常将直流输出电压B_Vcc施加到点p B 。通过上述结构，即使在用于提供直流输出电压B_Vcc的直流电源装置中发生短路等故障时，直流电源装置的直流输出电压B_Vcc也不大于4.0V。因此，即使在系统A中配置的运算电路的额定电流为2mA，也将MELF电阻器R 1 的电阻值设定为2kΩ。因此，构成低通滤波器的寄生电容被有效地从信号传送路径L消除。版权所有：（C）2007，JPO＆INPIT

Specially, a status message that is data in a digital form reaches bus subscribers 18 and 20 and is compared with status information that is preliminarily set. Specially, the bus subscribers 18, 20 and 16 check whether a status message is transmitted and received within failure allowable time that is preliminarily set or not. When an error is detected, a system, a device or a facility is shifted to a safe state.
