System integrators and OEMs often develop applications that require PLC control, but that settle on simple text displays due to limited budget. Unitronics, a trendsetter in the field of all-in-one PLC + HMI integrated controllers, has specifically developed a device for these situations: Samba™. Samba™ is an all-in-one, palm-size controller. The beautiful HMI 3.5” QVGA 16-bit touchscreen enables data entry and display of variable data, including color Trend graphs and alarm screens. Samba supports 24 user-designed screens, and up to 40 images per application. The integrated PLC controller offers a broad range of features including 2 auto-tuned PID loops, time-based RTC control, datalogging, recipes and more. Internal memory holds 0.5 MB of application logic, plus 512K for fonts and 0.5 MB for images.Onboard I/Os offer digital, analog, and high-speed functionality.
The flat fascia and IP66/IP65/NEMA4X rating makes Samba an excellent fit for the food & pharmaceutical industries--ideal wherever spray/wipe down requirements apply. Samba offers a built-in RS232 port. You can add an additional RS485 serial, Ethernet, or CANbus port. Samba supports GPRS/GSM, email, SMS, as well as industrial TCP/IP protocols, MODBUS, DF1 slave, CANopen, J1939 and more—and it may be adapted to any 3rd-party protocol. Unitronics free VisiLogic software provides a single simple environment for hardware and communications configuration, Ladder application development, and HMI design, including a free library of industrial images. Free utilities support remote PC access and data export. Unitronics offers free technical support for all of their products, and an active user forum.
