PROGRAMMABLE CONTROLLER
First Claim
1. A programmable controller that controls an industrial controlled device, comprising:
- a storage unit that stores therein a control file for controlling the controlled device, to which a name described in character code relating to a first encoding method is assigned;
a system unit that accesses the control file stored in the storage unit in response to a request from an external device;
a character-code conversion table that associates character codes relating to a plurality of encoding methods including the first encoding method with one another for every character code decoded to the same character; and
a character-code management unit which, in a case where an external device using a second encoding method different from the first encoding method is connected to the programmable controller and the character codes relating to the first encoding method are associated with character codes relating to the second encoding method one another in the character-code conversion table, converts an encoding method for a character code used to describe the name of a control file between the first encoding method and the second encoding method using the character-code conversion table at the time of transferring the name of the control file to be accessed between the external device and the system unit.

Abstract
To decode a file name set to a PLC to the same name even if a plurality of external devices using different character-code sets are connected to the PLC, the PLC includes a system unit that actuates the control file using a multilingual character-code set A, a character-code conversion table that associates character codes relating to a plurality of character-code sets with one another for every character, and a character-code management unit that converts description of the name of the control file between the description relating to the multilingual character-code set A and that relating to the local character-code set A using the character-code conversion table when the name of the access-target control file is transferred between the external device using the local character-code set A and the system unit.
