Abstract

PURPOSE: To obtain the programmable controller not required to stop all the controllers, even if any failure is occurred in I/O section through the split management of the I/O sections in required block number.
CONSTITUTION: The programmable controller consists of the operation section AL1 including machine section, control section CE1 providing the failure detection function for input and output signal processing I/O, and input and output section I/O, which is split into required block number. Similarly, the control section CE1 consists of the transmission control circuit CS, reception control circit CR, buffer registers BS, BR, failure detection circuit E1 and failure display section L1 for a plurality corresponding to I/O, and if the failure detection circuit E1 detects a failure, it is displayed on the failure display section L1 and fed to the operation section AL1, which controls only I/O other than I/O having a failure. The restoration after failure is made from the start from the operator.
