The invention relates to a transmitter for transmitting a process variable to a programmable logic controller. In a current mode a 4-20 milliamp current is fed into a burden and in a voltage mode 0-10 Volt signals are generated. The transmitter includes a process value input, a current stage, a voltage stage and a U/I output for the current or the voltage signal, and a U/I control input for switching between the two modes. The transmitter is configured to feed a current which is dependent on the voltage across the burden into the current stage via a resistor and thus to compensate for a current loss at the voltage stage which is dependent on the voltage across the burden.

A programmable controller allocates times obtained by dividing executable time in one operation cycle to a plurality of paths, executes sequence programs of the paths in the respective allocated times, and accumulates remaining time as extra time when execution of each of the sequence programs ends before the end of the allocation time. When it is determined that surplus time occurs on the basis of the accumulated extra time, the programmable controller determines whether each of the sequence programs is executed after being divided, and executes a remainder of a divided sequence program in the surplus time in accordance with a result of the determination.

The present invention relates to generally to programmable logic controllers (PLCs), and more particularly to a system and method to enables a user to accelerate the generation of PLC programs. The system includes a set of specific keywords and an internal algorithm that in combination with the industrial process information provided by the user, creates a methodology for PLC program generation, which is flexible enough to adapt to the user, PLC programming strategies, and other standards and practices.

An object is to provide a function of managing data exchanged with an external device. A control device defines a publishing setting of a process value in accordance with information on one or both of an execution result of a control program and an operating state of the control device. The control device exchanges a data set including a part of one or more process values with the external device in accordance with the defined publishing setting.

A process for integrating an industrial automation system with an Internet of Things (IoT) system may include providing access to a cloud-based platform, the cloud-based platform having a user interface. The user interface provides for easily displaying and changing configuration parameters describing a gateway module, a data acquisition module, and a sensor data channel associated with an industrial automation system wherein the data acquisition module can collect and process data from the sensor data channel and communicate that sensor data and any related processed information to a gateway module. The gateway module may also communicate configuration information to the data acquisition module and sensor data channel. The process may use the cloud-based platform to generate a memory map of the IoT system which can be used by a PLC or similar device of the industrial automation system to configure the IoT system and display data collected from the IoT system.
