摘要: An industrial control system providing security against tampering or modification generates periodic state thumbprints defining a state of control elements that may be forwarded to a security or safety appliance for comparison to a benchmark thumbprint indicating no tampering. The transmitted state thumbprint may capture not only programs but also configuration and environmental states of the control element.

摘要: Systems and methods are provided to facilitate correct execution of a machine jog operation where a plurality of interfaces can generate a machine jog command, which is received by an industrial controller. One or more machine jog commands can be received and state data is maintained regarding whether a machine jog command has been received. An OR gate logic operation is performed on the state data to determine whether a machine jog operation has been received from any of the plurality of interfaces, and in the event of receiving a machine jog operation, a control command is generated to effect a machine jog operation. The plurality of interfaces enable interaction with the controller, to facilitate control of a machine from a plurality of locations. The system can be expanded to include further interfaces. Also, information regarding a machine jog command can be published to the plurality of interfaces.

摘要: Systems and methods are provided to facilitate receipt of tag requests from one or more interfaces, based upon which a single tagset is compiled at a controller comprising all the requested tags for a given update rate, whereupon the single compiled tagset is subsequently forwarded to the one or more interfaces. A controller generates a superset of tags associated with an industrial process. Each interface can request a copy of the superset, from which the required tags are selected. The controller receives the requested tags from all of the interfaces and combines the requested tags into a single tagset, for a given update rate, comprising the various parameters associated with the tags. At the selected update rate, the tagset is forwarded to the interfaces. A masterset can be utilized to identify the sequence of tags in a tagset and check code can ensure continuity of the tags in the tagset.
