Remote I/O Port For Transfer Of I/O Data In A Programmable Controller
US Patent:
4809217, Feb 28, 1989
Filed:
Oct 31, 1985
Appl. No.:
6/793588

Assignee:
Allen-Bradley Company, Inc. - Milwaukee WI
International Classification:
G06F 1312, G06F 1516
US Classification:
364900
Abstract:
A method and apparatus for access to a programmable controller at a remote location. A peripheral device with a peripheral processor is connected to a port on an I/O module. Blocks of discrete and block transfer data are transferred to and from a common memory in the I/O module where the data is accessible to a serial communication controller that interfaces the module to a high speed serial data channel. Asynchronous communication is provided between the serial communication controller and the peripheral device using a circular buffer in the common memory. Timing considerations are also disclosed.

US Classification:
364132
Abstract:
An inter-processor communication module is inserted into a slot of an equipment rack of the type used to connect I/O modules to system processors in a programmable controller. Using two of the inter-processor communication modules in two respective racks, a supervisory processor is connected to two respective local area processors in a distributed control system. The inter-processor communication module has a serial channel controller that connects to the supervisory processor through a serial I/O port and a serial communication channel to communicate blocks of I/O status data. The serial channel controller is coupled to a backplane controller through a common memory and arbitration circuitry to exchange blocks of I/O status data. The backplane controller, which is also a part of the inter-processor communication module, plugs into the backplane of the rack and exchanges blocks of I/O status data with a local area processor. The two controllers also exchange processor status data to coordinate communications which are initiated by the supervisory processor and the local area processor.
