基于ADAM模块的物料均匀配比系统

*ADAM Repeater (optional)

a. Host computer

Any computer or terminal that can output in ASCII format over either RS-232 or RS-485 can be connected as the host computer. When only RS-232 is available, an ADAM RS-232/RS-485 Converter is required to transform the host signals to the correct RS-485 protocol. The converter also provides opto-isolation and transformer-based isolation to protect your equipment.

b. Power supply

For the ease of use in industrial environments the ADAM modules are designed to accept industry standard +24VDC unregulated power. Operation is guaranteed when using any power supply between +10 and +30VDC.

c. ADAM Isolated RS-232/RS-485 Converter (optional)

When the host computer or terminal has only a RS-232 port, an ADAM Isolated RS-232/RS-485 Converter, connected to the host’s RS-232 port, is required. Since this module is not addressable by the host, the baud rate must be set using a switch inside the module. The factory default setting is 9600 baud.

d. ADAM Repeater (optional)

When communication lines exceed 4000ft (1200meter) or the number of ADAM modules connected is more than 32, a repeater should be connected to expand the first segment. Up to 8 Repeater modules can be connected allowing connection of up to 256 ADAM modules. As with the Converter module, the Repeater module is not addressable by the host and the baud rate must be set by changing the switch inside the module. The factory default setting is 9600 baud.

3.4.2 建立和配置亚当模块的环境

*亚当模块

*一个主机，例如一个可兼容IBM PC/AT，用一个RS-232或RS-484点输出ASCII字符 *亚当模块的电源要求（+10 到+30VDC） *亚当系列软件应用

*亚当隔离RS-232/RS-485转换器 （可选） *亚当转发器（可选）

a. 主机

任何主机或终端可以用ASCII格式输出优于任一个RS-232或RS-485连接。 当仅有RS-232可用时，一个ADAM RS-232/RS-485转换器是被需要用来传送主机信号到正确的RS-485协议。这个转换器提供光隔离和传送基数隔离用来保护你的设备。

b. 电源需求

在工业环境中，亚当模块通常被设计用工业标准的24VDC不规律电源。当在电源+10 到+30VDC之间应用时，操作是安全的。

c. 设置

当主机或终端仅有一个RS-232节点时，一个亚当隔离RS-232/RS-485转换器连接到主机的RS-232节点上是被需要的。当此模块通过主机时没有地址，有一个模块的内置开关设置波特率。初始化被设置为9600波特率。

d. ADAM-4017 8通道模拟输入模块

当传输线超过4000ft（1200米）或连接亚当模块的数量超过32个时，一个转发器将被连接到扩展的第一段上，达到8个转发器模块的将被允许连接256个亚当模块。当用转发器模块时，转发器模块没有地址，通过改变模块的内置开关来改变主机和波特率的设置。初始化设置为9600baud.

3.6.4 Analogy Output Calibration

Model: ADAM-4021

The output current of analog modules can be calibrated by using a low calibration value and a high calibration value. The analog output modules can be configured for one of two ranges: 0-20mA and 4-20mA. Since the low limit of the 0-20mA range, 0mA, is internally an absolute reference (no power, or immeasurably small power) just two levels are needed for calibration: 4mA and 20mA.

1. Apply power to the analog output module and let it warm up for about 30 minutes. 2. Assure that the module is correctly installed and that its configuration is according your specifications and matches the output range you want to calibrate. You can do this by using the ADAM utility software. (Refer to Appendix D, Utility Software.). 3. Connect either a 5-digit millimeter or voltmeter with a shunt resistor (250Ω, 0.01%, and 10ppm) to the screw terminals of the module.

4. Issue the Analog Data Out command to the module with an output value of 4mA. 5. Check the actual output value at the modules terminals. If this does not equal 4mA, use the “Trim” option in the “CaLibrate” sub menu to change the actual output. Trim the module until the millimeter indicates exactly 4mA or in case of an voltage meter with shunt resistor, the voltage meter indicates exactly 1V. (When calibrating for 20mA using voltage meter and shunt resistor, the correct voltage would be 5V.).
