Note that most nodes include built-in documentation. When selecting a node, relevant information is displayed on the Properties panel.
Functional Nodes, or just nodes, provide a wide range of functionalities, such as connectivity with PLC, interface boards, support for protocols and even arithmetic operations. Below is a list of all major nodes and its functionalities.
||Provides connectivity with an Advantech USB 4750 interface board. Used for wiring PLC or any other type of hardware requiring opto-isolated digital I/O.
||Provides connectivity with and Advantech USB 4704 interface board. Used for wiring PLC analog I/O (0-10V). Can also be used for wiring microcontrollers or any other TTL hardware (5V).
Although the Advantech USB-4704 board provides digital I/O, it's not opto-isolated and can't be used directly with PLC digital I/O without additional electronics.
|Automgen 16D8A TCP/IP
||Provides connectivity with Automgen through a TCP/IP server (supports 16 digital and 8 analog values - better performance).
|Automgen 64D16A TCP/IP
||Provides connectivity with Automgen through a TCP/IP server (supports 64 digital and 16 analog values).
These nodes allow CONNECT I/O to be used as a SoftPLC. Each category described below includes many nodes, most of which are described on the standard IEC 61131-3 and available on any PLC.
||Arithmetic operators (e.g. +, - , *, /, etc.).
||Logical operators (e.g. AND, OR, NOT, XOR, etc).
||Relational and equality operators (e.g. <, <=, =).
||Down counters, up counters and up/down counters.
||Nodes that don't fit in any other category (e.g. converters, PID controller, etc.)
||On delay timers and off delay timers.
||Falling and rising edge triggers.
||Detects if a keyboard key is pressed.
||Toggles a Boolean value with a keyboard key.
||Plots data in real-time with LiveGraph.
||Provides connectivity with WinPLC-Engine and WinSPS-S7 (MHJ-Software) - for analog values.
