Data Formats and I/O Ranges

B.1 Analog Input Formats

The ADAM analog input modules can be configured to transmit data to the host in one of the following data formats:

-Engineering Units -Percent of FSR

-Twos complement hexadecimal -Ohms

B.1.1 Engineering Units

Data can be represented in engineering units by assigning bits 0 and 1 of the data format/checksum/integration time parameter with value 00.

This format presents data in standard units such as degrees, volts, millivolts and milliamps. When the value in engineering format is converted to computer language, it is presented in seven characters. These characters may include sign and decimals. However, the number of characters can not exceed seven.

Data is grouped into a plus (+) or minus (-) sign, followed by five decimal digits and a decimal point. The input range which is employed determines the resolution or the number of decimal places used as illustrated in the following examples:

Example 1

The input value is -2.65 and the corresponding analog input module is configured for a range of ±5 V. The response to the Analog Data In command is: -2.6500 (cr)

Example 2

The input value is 305.5o C, and the analog input module is configured for a type J thermocouple whose range is (0o C to 760o C). The response to the Analog Data In command is: +305.50 (cr)

Example 3

The input value is +5.653 V. The analog input module is configured for a ±5 V range. When the engineering unit format is used, the ADAM Series analog input modules are configured so that they automatically provide an over-range capability. The response to the Analog Data In command in this case is: +5.6530 (cr)
