Procedure for supplying, storing and displaying elevator control data

Procedure for supplying and modifying data required in a control system of an elevator of an elevator group and for producing instructions needed for at least one of installation, maintenance, repair and modification on a display in the control system, comprising the steps of:

• storing parameter data of the control system and preselected instruction data for each operator carrying out work in a separate individualized storage unit;
• when modification, repair or maintenance work is being carried out on the elevator, establishing a communication link between said separate storage unit and a data storage of a control unit in the control system;
• supplying said data stored in said separate individualized storage unit to said control unit;
• saving the supplied data in the control unit;
• producing instructions to the operator in accordance with the parameter data and preselected instruction data supplied from the separate individualized storage unit and saved in the control unit;
• carrying out at least one of installation, maintenance, repair, and modification in accordance with said instructions;
• storing parameters concerning elevator-specific configuration of a decentralized elevator control in a non-volatile memory in said separate storage unit;
• and
• during a start-up drive and after changing the configuration, checking the configuration data of all the elevators of the elevator group.

An elevator control apparatus comprising:

• a control unit which controls the operation of the elevator;
• an operator interface unit which tests, monitors and alters the operation of the elevator, said operator interface unit comprising a connection which connects a separate, individualized storage to said operation interface unit;
• means for determining, from the separate individualized storage unit, parameter data specific to an operation and preselected instruction data specific to an operator and said operation;
• an internal storage unit in said control unit which stores said parameter and preselected instruction data from said separate individualized storage unit;
• means, in said control unit, for producing instructions in accordance with said data stored in said internal storage unit and for outputting said instructions to said operating interface unit;
• a non-volatile memory in said separate storage unit storing parameters concerning elevator-specific configuration of a decentralized elevator control;
• and
• means for checking, during a start-up drive and after changing the configuration, the configuration data of all the elevators of the elevator group.
