Other characteristics


The two-wire variant of the modular telecontrol system MFW was especially engineered to transmit data on electrically isolated two-wire cables. By it the common, partly existing signal cables can be used, so there is no need of laying special cables in the ground. The two-wire line guarantees a very high noise immunity of the data transmission. Their cable routing can be done either in line, star or branch system. The telecontrol system consists of a central station and an outstation in its minimum configuration. Each station requires at least one basic module, which can be fitted up to a maximum of 15 expansion modules. These are connected via the system bus cable, which is in the scope of supply to the basic module. The master co-ordinates the data exchange in a pooling scheme. In the event of a fault, the system detects the defective communication and reports it optically and via relay contact both in the master (LED matrix) and in the respective outstation (OK LED). The accessibility of each connected station can additionally be indicated through a binary contact at any point of the two-wire system, if appropriate I/O modules are used. Additionally the information can be given on a serial interface to analyze this information likewise. After the cause of the fault has been recti-fied, normal operation is resumed automatically. The system configuration is easy and com-fortable. Each important settings like station address (1 – 31), the module number (0 ... 254), static value/counted value in the case of digital I/O and current voltage in the case of analog signals etc. can be made by DIP switches.
