ROM MODULE FOR SEQUENCE PROGRAM.

摘要

A ROM module for a sequence program provides sequence processing corresponding to a command output from a numerical control unit and outputs the processing result to the machine side. The ROM module is provided with a ROM (102a) for storing a sequence program, a printed circuit board (102) on which the ROM is mounted, a casing (101) housing the printed circuit board, and a connector (102e) which is attached to the printed circuit board and is exposed on the outside of the casing. Sequence programs can be read out from the ROM and written thereinto through the connector.
