Abstract
A portable programming device is used in a supervisory remote control system comprising a signal transmission unit for supplying a signal according to a TDM (Time Division Multiplexing) manner, first and second terminals having individual addresses, and a signal line connecting therebetween. According to a set of relation data including an address correspondence between one of the second terminals and one of the first terminals and control data including control parameters of a load, the load connected to the one of the second terminals can be controlled according to a supervisory input provided to the one of the first terminals. The programming device has a hand-held type housing for accommodating a display, operation unit for programming an address, the relation data and the control data, data memory, and a signal processor for transferring the address to a required one of the first and second terminals, and transferring the relation data and the control data stored in the data memory to the transmission unit. The signal processor further comprises a data retrieving unit for retrieving at least one set of the relation data and the control data corresponding to an address designat…
