An electronic device is coupled to electronic paper display. The electronic device may be utilized as part of an industrial control system. The central processing unit programmatically and automatically updates the electronic paper display with information to be displayed.

An industrial integrated development environment (IDE) supports open or extensible application programming interfaces (APIs) that enable end users (e.g., plant asset owners, original equipment manufacturers (OEM), system integrators, etc.) to build upon the IDE's development platform to create custom views or to code custom functionality. This can include, for example, defining a control programming syntax supported by the industrial IDE, customizing a development environment view afforded by the IDE's interface, modifying or creating project editing functions, defining customized programming guardrails designed to guide compliance with in-house programming standards, or other such IDE customizations.

A communication method between a master and a device, the master transmits in a subcycle a received condition message (RCM) for an immediately prior subcycle, wherein the RCM is an ACK when a transmission from the device in the preceding subcycle was correctly received and the RCM is a NACK when a transmission from the device in the preceding subcycle was not correctly received, comprising: including in each transmitted condition message a current priority data acknowledgement flag (CPDAF), the CPDAF being transmitted set in each condition message for each subcycle of an offset cycle after the master correctly received in a current cycle a priority data message, the offset cycle being defined as the second and subsequent subcycles of a current cycle and the first subcycle of a next cycle, the CPDAF being transmitted as cleared otherwise.

An input-output device includes an input circuit unit including an input-signal-setting storing unit that stores a plurality of ON conditions of the input signal and an input circuit that determines whether any one of the ON conditions of the stored input signal holds, a computing unit including an output-signal-setting storing unit that stores information in which the ON conditions of the input signal, output ports for outputting an output signal, and specifications of the output signal are associated and an output-signal selecting unit that generates, on the basis of a determination result of the input circuit and the stored information, an output command indicating the output ports and the specifications of the output signal, and an output circuit unit including an output circuit that outputs, to the output ports indicated by the output command, the output signal according to the specifications indicated by the output command.

An automation field device comprises a first, a second, and a third connection pin; and a field device electronics designed to be operated either in a two-conductor mode or in a three-conductor mode. The field device electronics have an energy supply unit designed to provide internal energy supply exclusively by means of the fed current in the two-conductor mode. In the three-conductor mode, an additional auxiliary current is to be fed to the field device electronics via an additional single-wire line connected to the third connection pin, and the energy supply unit is also designed to provide the internal energy supply via the fed current and the fed additional auxiliary current. Furthermore, the field device electronics are designed to use the additionally fed auxiliary current for internal energy supply only if the current fed by means of the two-wire line is not sufficient for the internal energy supply.

Various systems and methods for implementing a software defined industrial system are described herein. For example, an orchestrated system of distributed nodes may run an application, including modules implemented on the distributed nodes. In response to a node failing, a module may be redeployed to a replacement node. In an example, self-descriptive control applications and software modules are provided in the context of orchestratable distributed systems. The self-descriptive control applications may be executed by an orchestrator or like control device and use a module manifest to generate a control system application. For example, an edge control node of the industrial system may include a system on a chip including a microcontroller (MCU) to convert IO data. The system on a chip includes a central processing unit (CPU) in an initial inactive state, which may be changed to an activated state in response an activation signal.

Various systems and methods may be used to implement a software defined industrial system. For example, an orchestrated system of distributed nodes may run an application, including modules implemented on the distributed nodes. The orchestrated system may include an orchestration server, a first node executing a first module, and a second node executing a second module. In response to the second node failing, the second module may be redeployed to a replacement node (e.g., the first node or a different node). The replacement mode may be determined by the first node or another node, for example based on connections to or from the second node.

A system and method for detecting a failure in a redundant signal path during operation of the redundant path is disclosed. A test signal is sequentially injected into each signal path while an input signal is conducted by the other signal path not receiving the test signal. The test signal is selected at a frequency to verify operation of a filter connected in series along each path. A processor generates the test signal, injects the test signal at the input of the filter, and receives the output of the filter. The processor then generates a frequency response of the filter in each signal path as a function of the output from the filter and of the original test signal. The frequency response obtained along each of the redundant signal paths is compared to each other to detect a failure of one of the filters present along the respective signal paths.
