摘要： In a system for performing signal transmission, through a field bus, between field devices and higher-rank apparatuses connected on a transmission line, the field devices are of the analog signal type. A substitution device is provided between the analog type field devices and the field bus. The substitution device acts to perform communication on the field bus as a substitute for the field devices. By the substitution device, the field devices can be gradually changed to those adapted to the field bus as occasion demands, so that an existing system can be transformed step by step into a field bus system.

摘要： A field sensor communication system is arranged in such a manner that, when an electric current, the level of which can be changed to a predetermined level, is, transmitted to a signal transmission line having at least one load resistor connected in series and the voltage change across the load resistor due to the change in the electric current is detected as a reception signal, the predetermined level is cyclically changed to a plurality of levels so that the level at which a good signal reception condition can be realized is determined to perform a communication at the thus determined level. As a result, even if the value of the load resistor in the signal transmission line is changed, the communication can be performed normally, since an undesirable change of the level of the reception signal can be prevented.

摘要： A Manchester code signal is used as a communication signal to be superimposed onto an operating current. The amplitude value in the plus direction with respect to an average current value is made larger than that in the minus direction, and the time width of an "H" level in one bit time is made smaller than that of an "L" level so as to establish the average current value into a low level. Accordingly, it is possible to make the average current value at the time of not-communication equal to that at the time of communication, and it is also possible to establish the average current value to a low level.

摘要： A field bus system may be used in which transmission ability of the system can be maintained even if communication error occurs due to noises or failure of a transmission line. The system can be easily shifted at a lower cost from a conventional system to the field bus system without degrading the high reliability thereof. The transmission line is constituted by a multiple-cable transmission line having at least three transmission cables. An external power supply supplies power to field devices through a pair of transmission cables of the multiple-cable transmission line. The field devices are connected to the transmission cables through a transmission line switching unit constituted by a plurality of rectifier elements, so that the field devices are supplied with current flowing in one predetermined direction when any of the pairs of transmission cables is selected. The external power supply monitors a failure of a currently used pair of transmission cables and, upon detection of failure of the currently used pair of transmission cables, the failed pair is replaced by a normal pair of transmission cables such that the field devices are continuously supplied with power.
