称重仪表也叫称重显示控制仪表，是将称重传感器信号（或再通过重量变送器）转换为重量数字显示，并可对重量数据进行储存、统计、打印的电子设备，常用于工农业生产中的自动化配料，称重，以提高生产效率。
概述
The compact size of this highly functional weight indicator is a plus for crowded industrial areas. Choose the 390-DC with standard five-key operation or IQ-Plus 590-DC with a complete keypad for easy configuration and calibration. Both models operate on either battery or AC power and provide the flexibility of a counting mode.
特性
1. Full numeric keypad
2. Keyboard entry of piece weight, tare weight, calibration and sample size
3. Display tare button
4. Powered by 6 C cell alkaline batteries for complete portability (batteries not included)
5. (3) 300-character print ticket formats
6. Power for (4) 350ohm load cells or (8) 700ohm load cells
7. Supports 4- and 6-wire load cell connections
8. EDP port for full duplex, RS-232 communications
9. NEMA Type 4X/IP66-rated stainless steel enclosure
10. LCD display, 1in (24.5mm), 6-digit
11. AC adapter for 115 or 230 VAC power
12. Configurable standby mode to prolong battery life
13. RATTLETRAP® 3-stage digital filtering
14. Configurable units multiplier
15. Configurable analog-to-digital measurement rate
16. Self-resetting thermal fuse
17. Configurable with Revolution® software
随着科技的发展进步, 称重仪表需要和PLC系统通过[1] 连接的需求越来越多. 因为MODBUS是个开放的协议, 需要的接口为RS232/RS485 串口 或是 以太网, 对设备的硬件接口要求不高, 目前所有的PLC 和 HMI 产品都有串口, 而且95% 的产品都支持 MODBUS-RTU, 随着以太网技术的飞速发展,现在中高端PLC和HMI产品都带以太网接口,而且都支持MODBUS-TCP 协议,但前整个称重行业的产品支持MODBUS 的仪表还不多, 仅有几款产品支持MODBUS-RTU, 支持MODBUS-TCP 的更少
