Welcome What is Connect I/O Connect I/O is a funcon blocks SoPLC which is able to communicate with dierent types of technologies. It enables the creaon and control of data ows between input and output points. This diagram applicaon can be connected to both soware and hardware and work as a bridge between them. Connect I/O has a modular design which allows new funconalies to be implemented with plugins.

How Does It Work Connect I/O is built on top of a shared memory map technology (.NET assembly EngineIO.dll) designed for ecient inter-process communicaon, i.e. data exchange with third-party applicaons. This is how Connect I/O interfaces with other Real Games applicaons.
Inputs, Outputs and Memories Inputs, Outputs and Memories are the basis of the shared memory map and by convenon dened from the controller’s point of view. This means that inputs values are read only, outputs and memories can be read and wrote to.
Built-In Datatype Connect I/O provides most common datatype available in high level programming languages such as Java and C#. Inputs, Outputs and Memories

Sources and Plugins Source nodes are used as a source of data for the diagram. The source nodes BIT, NUMERICAL, STRING and DATETIME provide data compable with all the supported datatype. Plugins are nodes that add funconalies to Connect I/O. Apart from the Real Games provided plugins, users may develop their own in order to t their needs.

INPUTS Nodes that read data from the memory map inputs. OUTPUTS Nodes that read and write data to the memory map outputs. MEMORIES Nodes that read and write data to the memory map memories. SOURCES Nodes that provide data. BIT; NUMERICAL; STRING; DATETIME - source data SYSTEM TIME- System date and me CYCLETIME- Update cycle me TAGS Input and output nodes are automacally detected by Connect I/O. When an external applicaon sets a name to an input or output memory it is automacally detected and added to the TAG panel. PLUGINS A list of nodes that add funconalies to Connect I/O.

Plugins What is a Plugin Plugins are .NET 4.5 assemblies containing classes that inherit from CustomNode or CustomNodeAsync. These assemblies must be available on the Connect I/O plugins folder to be automacally loaded at startup. The CustomNode class is the base class for nodes running logic on the same thread as Connect I/O. A good example of such nodes is the down counter (CTD) which executes code that will never block the Connect I/O thread. The CustomNodeAsync is the base class for nodes which will execute logic on a dierent thread. These nodes are typically used when the delay caused by the execuon of a node logic may cause Connect I/O to block or run too slow. An example would be a node execung TCP/IP communicaons or a node accessing a DAQ driver.
