US Patent:

52457044, Sep 14, 1993

Filed:

Mar 22, 1990

Appl. No.:

7/497461

Inventors:

Mark S. Weber - Germantown WI
Joseph T. Bronikowski - Milwaukee WI
Brian T. Hill - Mequon WI
David J. Sackmann - Milwaukee WI

Assignee:

Square D Company - Palatine IL

International Classification:

G06F 1546

US Classification:

395200

Abstract:

A system allows for transferring messages between microprocessor based devices, such as programmable logic controllers (PLC), and a host computer over an Ethernet communications network. At the host computer level, these messages can be directed globally or locally. The host computer can immediately obtain messages from a programmable logic controller without interruption of the execution of the PLC's ladder program. The host computer can also receive unsolicited messages from the PLC.

Appl. No.:

7/497451

Inventors:

Joseph T. Bronikowski - Milwaukee WI
Brian T. Hill - Mequon WI
David J. Sackmann - Milwaukee WI
Mark S. Weber - Germantown WI

Assignee:

Square D Company - Palatine IL

International Classification:

G06F 1312

US Classification:

395200

Abstract:

A control system allows for transferring messages between a programmable logic controller and a host computer over a serial data communications network. The programmable logic controller executes a ladder program and has an integral network interface module for permitting direct communicative coupling to the communications network. Messages can be received and sent by the programmable logic controller without interruption of the execution of the ladder program. The programmable logic controller can receive unsolicited messages from the host computer.

Filed:

Mar 11, 1992

Appl. No.:

7/850234

Inventors:

David J. Sackmann - Milwaukee WI
Brian T. Hill - Mequon WI
Joseph T. Bronikowski - Milwaukee WI
Mark S. Weber - Germantown WI

Assignee:

Square D Company - Palatine IL

International Classification:

G06F 1516

US Classification:

395325

Abstract:

A control system allows for transferring messages between a programmable logic controller and a host computer over an Ethernet communications network. The messages include a routing address specifying an originating drop number, a destination drop number, and a routing drop number. The system is responsive to the routing address for transferring the messages between the programmable logic controller and the host computer. The host computer can immediately obtain messages from a programmable logic controller without interruption of the execution of its ladder program. The host computer can also receive unsolicited messages from the programmable logic controller.

US Patent:

51310929, Jul 14, 1992

Filed:

Sep 1, 1989

Appl. No.:

7/402482

Inventors:

David J. Sackmann - Milwaukee WI
Brian T. Hill - Mequon WI
Joseph T. Bronikowski - Milwaukee WI
Mark S. Weber - Germantown WI

Assignee:

Square D Company - Palatine IL

International Classification:

G06F 1300

US Classification:

395800

Abstract:

A high speed control system allows for transferring messages between a programmable logic controller and a host computer over an Ethernet communications network. The host computer includes prioritized alarm queues for receiving prioritized alarms from the programmable logic controller. Alarms fall into either a local or a global category, and each category supports three types of alarms: warnings, alerts or faults. The system is responsive to the routing address for transferring the messages between the programmable logic controller and the host computer. The host computer can immediately obtain messages from a programmable logic controller without interruption of the execution of its ladder program. The host computer can also receive unsolicited messages from the programmable logic controller. The programmable logic controller can communicate with tasks within the host computer as though those tasks were other programmable logic controllers.
