The Basic I/O 1 1-1(Vol.1) THE BASIC I/O: BASIC I/Os are a family of small, industria l grade, remote data acquisition and control systems which exchange data with a Host computer via a serial comm unications link. Controlled by a wide range of software running on a Host computer, Basic I/Os are located near the sensors and actuators. The serial li[...]

The Basic I/O 1 1-2(Vol.1) A notable feature of the BASIC I/O is its ability to gather data and perform ranging and statistical operations on raw data before it is se nt to the Host. The Host can thus spend less time manipulating data and more time gather ing it. The following sections discuss the different signals the BASIC I/O can handle. ANALOG [...]

The Basic I/O 1 1-3(Vol.1) ANALOG OUTPUTS: Analog output modules are 100% isolated. These self-sourcing m odules provide the voltage or current necessary to drive standard instrument ation loads. All are updated every 10 Ms, or 100 times per second. Analog output instruction types are: Level Value Can set output levels, as a fraction of the module?[...]

The Basic I/O 1 1-4(Vol.1) DIGITAL INPUTS: Digital input modules detect the presence or absence of a field signal. Module types vary from AC to dry contact sense. Because the industry standard modules are optically isolated, the response time performance of digital input instructions can be limited by the delay in the input modules themselves. Some[...]

The Basic I/O 1 1-5(Vol.1) DIGITAL OUTPUTS: Digital output modules, commonly referred to as so lid state relays, control external AC or DC power sources. A dry-contact (mechanical relay) with very low contact resistance is also available. Digital output instruction types are: Set outputs Can set individual or multiple outputs On or Off. Pulse Gener[...]

The Basic I/O 1 1-6(Vol.1) SYSTEM THROUGHPUT: Input data throughput is the time from beginning of the first character of an input instruction to the end of the last character of the response. The processing time of the Host computer will affect the effective throughput. Output Execution throughput is the time from th e beginning of the first charac[...]

The Basic I/O 1 1-7(Vol.1) It should be noted that the values in th e preceding throughput tables and the following equations reflect only the communications overhead and inherent processing delay of the BASIC I/O equipment. In practice, a significant amount of overhead will be devoted to other processing tasks such as screen updates, Data logging,[...]

The Basic I/O 1 1-8(Vol.1) COMMUNICATION PROTOCOL: The BASIC I/O Communication Protocol is 100% comp atible with the Opto-22 Optomux™ protocol.
