PCT No. PCT/CH86/00022 Sec. 371 Date Dec. 1, 1986 Sec. 102(e) Date Dec. 1, 1986 PCT Filed Feb. 18, 1986.Hoistway data which are indicative of predetermined elevator car positions at respective predeterminate hoistway locations, are generated without installations of actuating members in the elevator hoistway and transmitters at the elevator car. For this purpose, a memory is provided and has stored predeterminate positional numbers representative of the predeterminate hoistway locations. The predeterminated positional numbers are transmitted to a register in a travel direction dependent sequence during travel of the associated elevator car. A pulse transmitter is driven by the elevator car and the thus generated pulses are summed-up in a counter to positional numbers which correspond to respective car positions. The positional numbers of the counter and the predeterminate positional numbers transmitted to the register are compared with one another during travel in a comparator during elevator car travel. In case of identity, a signal representing a hoistway datum is generated and a switching member associated with the respective hoistway location is activated.
