An input/output (I/O) device for a distributed modular I/O system includes a base adapted to be connected to an associated support structure. A terminal block is connected to the base and includes a plurality of wiring connections adapted to be connected to field wiring of an associated controlled system. The I/O device further includes first and second I/O modules each including a plurality of removable single-channel I/O submodules that are each releasably connected to the base and each configured for a select I/O operation for input and output of data relative to the associated controlled system. One or more pairs of the single-channel I/O submodules can be configured to be redundant within or between the first and second I/O modules. Each of the single-channel I/O submodules is operatively connected to wiring connections of the terminal block through the base. The I/O device further includes first and second network switches connected to the base. The first and second network switches are adapted to be respectively connected to first and second backplane circuits. The I/O device further includes first and second system modules connected to the base and each respectively connected to both of the first and second network switches. The first and second system modules are also each respectively operatively connected to all of the removable single-channel I/O submodules of both of the first and second I/O modules such that the first and second system modules control communication of I/O data between the first and second network switches and the single-channel I/O submodules.

To facilitate work for creating a data utilization program for collecting control data held by a PLC and a dashboard for displaying the control data. A setting device receives selection of a dashboard, receives designation of collection target data, creates setting data including a set of a template of the dashboard and a template of a data utilization program, and transfers the setting data to a PLC. A second executing section of the PLC executes, based on the setting data, predetermined data processing on the collection target data to generate display target data. The display target data is linked with a graph display component included in the template of the display data of the dashboard.

To efficiently collect and transfer monitoring target data in a PLC. The PLC includes a first execution engine, a holding section, and a second execution engine. Further, the PLC collects data stored in a collection target holding section according to predetermined collection setting, accumulates collected time-series data in a first buffer, and transfers the time-series data stored in the first buffer to the second execution engine via a bus. The second execution performs data processing of the transferred time series data, generates display data to be displayed on a dashboard, and provides the display data to an external computer.

A design assistance device assists design of a processing device to execute processing and includes an acquirer, divider, communication code generator, and outputter. The acquirer acquires processing code describing content of the processing. The divider divides the processing code into modules and determines, for each of the modules, an execution environment in which the module is to be executed, from among a plurality of execution environments provided on the processing device. The communication code generator generates, when a module of the plurality of modules includes partial processing prioritized for execution in a second execution environment other than a first execution environment determined for execution of the module, a communication code for communication between the first execution environment and the second execution environment to execute the partial processing in the second execution environment. The outputter outputs the plurality of modules and the communication code to the processing device.
