The Canvas 4 OCS Series, from Horner Automation, are all-in-one industrial control devices that includes: an HMI PLC as well as built-in I/O. They combine control, user interface, I/O and also networking into a single, integrated package. Unique features of the Canvas 4 OCS include:
- display of complex graphical objects including trends, gauges, meters, and animations
- high-performance graphic processing
- bright, 65,536 color graphical touch-sensing LCD display or a bright white touch-sensing LED backlit display capable of up to 16,777,216 colors
- advanced control capabilities including floating point, multiple auto-tuning PID loops, and also string handling capabilities
- all Canvas models include WebMI+, MQTT, Enhanced IEC, and also SAE J1939 features included as standard
Advanced Features of the Canvas 4 All-in-one HMI PLC
- removable media for 32 gigabytes of storage of programs, data logging, as well as screen captures
- CsCAN networking port for communication with remote I/O, other controllers, or PCs
- USB port for communication with PCs as well as for the programming of the HMI PLC
- configurable serial protocols for communication to drives, PLCs, or also other serial peripherals
- full featured HMI PLC, built-in I/O including high resolution analog, thermocouple, RTD, high-speed counters, PWM outputs, and relays (depending upon the Canvas 4 OCS model)
- advanced high-speed I/O capabilities
- Cscape programming software that allows all aspects of the Canvas 4 OCS to be programmed and also configured from one integrated application
- transflective screen models ending in -500 have heaters and are equivalent to the environmental specifications of the standard Canvas 4 -22 models
- transflective screen HMI PLC models ending in -108 do not have heaters, however they have equivalent environmental specifications to the standard Canvas 4 models (without dashes)
- optional communication add-on modules
- on board Ethernet port (10/100Mbps) for Cscape programming as well as application defined communication, with Auto MDI/MDI-X
Networking Capabilities of the Canvas 4 HMI PLC All-in-One Automation Controller
- (1) built-in 10/100 Ethernet port
- (1) integrated CAN port that supports either CsCAN, CANopen, SAE J1939, or DeviceNet Scanner
