AutomationDirect has added a low-cost CODESYS PLC solution for those who prefer CODESYS programming. CODESYS is the most widely used manufacturer-independent IEC 61131-3 development system on the market, and the new P2CDS-622 CPU features a CODESYS engine housed in a Productivity2000 controller form factor. This CPU offers plenty of communication capabilities and works seamlessly with low-cost Productivity2000 I/O modules.

The P2CDS-622 CPU is a compact, powerful processor providing 50 MB of user memory, two high-speedFigure 1: The CODESYS IDE provides full IEC 61131-3 programming with sequential function chart, ladder diagram, function block, and structured text options. Source: AutomationDirect Ethernet ports, support for several communication protocols including Ethernet/IP and MQTTS, two software selectable (RS-232 or RS-485) serial ports for peripheral device interfacing or controller networking, and micro SD data logging.

Monitoring and control signal interfaces are provided using the time-tested Productivity2000 I/O modules. These modules are easily inserted/removed from the base chassis and boast many convenience features including the patented high-contrast OLEDs on the analog/temperature modules.

The CODESYS IDE provides full IEC 61131-3 programming with sequential function chart, ladder diagram, function block and structured text options. Also included is continuous function chart (CFC) programming, which is an extension to the IEC 61131-3 standard and uses interconnected function blocks to represent control logic visually.

The CODESYS IDE is a free download, and included are over $400 in add-on licenses. The fieldbus add-ons include Modbus RTU and TCP, and Ethernet/IP scanner and adapter. The visualization add-on (WebVisu) allows users to create a web-based HMI for their application. The industrial internet of things (IIoT) library add-on provides MQTT clients with TLS, web client (http, https), AWS IoT Core Client, Azure IoT Hub Client, mail service (POP3, SMTP), SNTP service, SNMP library, SMS service and JSON functionality.

The Productivity CODESYS P2CDS-622 CPU is priced at $529, Productivity2000 I/O modules start at $57 and both the CPU and I/O modules come with a two-year warranty.
