A control system for factory automation includes a first unit and a second unit that exchange data with each other, and a synchronization module that synchronizes a control counter included in the first unit and a control counter included in the second unit using a clock. Each of the units includes an information storage that stores information on conversion for calculating a time from a counter value of the counter of the unit, the information being shared between the units.

A method and system are provided that synchronize one or more appliances to one or more users' schedules. Sensor data may be obtained from a sensor. The sensor data may indicate a state of a first appliance. A user location may be determined. A first characteristic of the first appliance may be obtained. Based upon the user location and the sensor data, a schedule indicating when the user will desire a state change of the first appliance may be determined. A feature of the first appliance may be dynamically modified to cause the first appliance to operate according to the schedule. A notice may be sent to the user that contains information about the first appliance.

A control system for factory automation includes a first unit and a second unit each including a timer, a data line over which data containing a timer value indicated by the timer is exchanged between the first unit and the second unit, a signal line that electrically connects the first unit and the second unit, and an adjustment module connected to the signal line and the data line. The adjustment module acquires, when receiving a trigger signal over the signal line, the timer value over the data line and matches the timer of the second unit with the timer of the first unit based on the timer value acquired.

The communication master repeats transmission of first information indicating a counter value of a synchronization counter of the communication master to the one or more communication slaves through a network. Each of the one or more communication slaves updates the counter value of the synchronization counter of each of the one or more communication slaves based on the received first information upon receiving the first information from the communication master. The communication master manages a total number of pieces of the first information transmitted for each of the one or more communication slaves, and estimates synchronization accuracy with respect to the communication master for each communication slave based on a number of transmissions of the first information for each communication slave.

A control system includes plural control devices connected to a network, each of the control devices including a program storage, an operation module, and an arbitration module. The program storage stores a control program including a command to calculate and update a control instruction that is a value related to control of a control target. The operation module operates the control program of the program storage of the control device. The arbitration module disposes plural control programs including a command to calculate and update an identical control instruction in another one of the plural control devices, and arbitrates an operation time between the plural control programs such that updatings of the identical control instruction do not conflict with each other in the plural control programs.

An optical measurement device configured for connection to an industrial network, the industrial network functioning to synchronize time between a master device and a slave device, the optical measurement device includes: an interface module configured to receive a synchronization signal transmitted on the industrial network from the master device within a fixed communication cycle; and a measurement unit configured to perform optical measurements in a measurement cycle. The measurement unit synchronizes when a measurement is taken with the communication cycle in accordance with the synchronization signal received by the interface module

A method synchronizes first and second simulation systems, each operating in a free running operation thereby exchanging data to run the simulation systems. The method includes: a) providing the first simulation system (PLCSIM) being enabled to run in cycles at a linear speed determined by repeatably setting a scaling factor (s.sub.n); b) providing the second simulation system (Process Simulate) to run in cycles at different speeds; c) the second simulation system requests at the end of a cycle a virtual time stamp from the first simulation system; d) calculating on the basis of the virtual time stamp a virtual duration time At.sub.nfs and on the basis of the virtual time stamp after completion of the cycle of the second simulation system a virtual duration time At.sub.nss; and e) calculating an update sn+1 for the scaling factor according the most recent scaling factor s.sub.n multiplied by At.sub.nss/At.sub.nfs.

A control system includes a control target and plural devices, and the control target and the devices are connected to a network. The control system includes a program storage provided in each device storing a control program that calculates control data using data exchanged with the control target, an execution module and a disposition module. The execution module is included in each device and causes a processor to execute programs including a disposed control program. The disposition module disposes control programs in one or more of the devices. The disposition module determines a device in which the control program is disposed from among the plural devices based on a communication delay time between the devices and information about a resource usable for execution of the control program of each device for each control program.

According to the present invention, when there is a change in a network configuration, timers of a changed network configuration are synchronized with a timer having high accuracy among the timers. This control system has a network configuration in which one or more control devices each for controlling a target can be communicably connected to a network, and each of the one or more control devices has: a timer for managing time with accuracy; a communicator for transmitting a control command to a target corresponding to said control device on the basis of the time managed by the timer; and a timer synchronizer that, when the network configuration is changed, time-synchronizes, among timers of each control device of a changed network configuration, timers with another timer having higher accuracy than the timers.
