All examples and diagrams shown in the manual are intended to aid understanding. They do not guarantee operation. • Unitronics accepts no responsibility for actual use of this product based on these examples. • Due to the great variety of possible applications for this equipment, the user must assess the suitability of this product for specific applications. -
Page 9: Chapter 1: Overview
™1 Vision OPLCs are programmable logic controllers that comprise an integral operating panel. Compactly designed, these controllers are compatible with different types of Unitronics’ I/O modules. This allows you to build Vision-controlled systems capable of automating a broad range of analog and digital applications. All Vision OPLCs offer RS232 communications, CANbus networking options, and a real-time clock (RTC). -
Page 10: Technical Description
Vision 230/260/280 User Guide Two types of I/O modules are compatible with Vision OPLCs. I/O modules are available in a variety of models. Snap-in I/O Modules plug directly into the back of a Vision OPLC, creating a self-contained PLC unit with a local I/O configuration. I/O Expansion Modules can also be easily integrated to greatly extend the system’s control capacity. - Page 11 Chapter 1: Overview Communications RS232 The controller comprises 2 COM ports. These may be used to download programs from a PC, or to establish communications with devices using the RS232 protocol. CANbus The controller comprises 1 port for CANbus networking purposes.
