Systems and methods are disclosed for time synchronization of operations in a control system. Synchronization networks and devices are provided for transferring synchronization information between controllers in a distributed or localized control system, which is employed in order to allow operation of such controllers to be synchronized with respect to time. Also disclosed are synchronization protocols and hardware apparatus employed in synchronizing control operations in a control system.

Protocol and method for multi-chassis configurable time synchronization

An industrial controller may communicate with a number of input/output (I/O) modules using an optimized connection packet assembled by a scanner communicating directly with the I/O modules and forwarding the optimized connection packet to the industrial processor. The optimized connection packet is communicated over a connection as part of a connected messaging system used to ensure highly reliable network communication. The need for higher data rates for some I/O modules as part of the optimized connection packet may be accommodated through the opening of a second redundant connection that provides the high-data-rate data in an interleaving fashion with the optimized connection packet, without upsetting the optimized connection packet or changing the use of the data by the industrial control program.

Methods and systems are disclosed for automatically generating an execution order for a control system function block diagram. The input data availability is determined for the inputs of the function blocks in the diagram, and an execution order is generated for the function block diagram according to the input data availability for the function block inputs. Also disclosed are methods and systems for generating a control routine from a function block diagram having a plurality of function blocks, wherein the control routine is generated from the function block diagram according to the execution order.
