PROGRAMMABLE CONTROLLER DATA PROCESSING METHOD, PROGRAMMABLE CONTROLLER AND TERMINAL

摘要

PROBLEM TO BE SOLVED: To reliably set data of power interruption attribute of a programmable controller to programmable controller operating data.;SOLUTION: A storage means (data memory 7) of the programmable controller 2 stores a hot data file 8 containing hot data composed of data running on the programmable controller 2. When there is the hot data file 8 in the storage means, the data memory 7 is set with the contents of the hot data file 8 by a CPU module 10 of the programmable controller 2 after initializing the programmable controller 2. A terminal 1 communicating with the programmable controller 2 extracts and stores the hot data stored in the programmable controller 2.;COPYRIGHT: (C)2009,JPO&INPIT
