本篇是系列文章的完结篇,前几篇文章借助 ADAM-6052 验证了 Modbus TCP 的协议细节,这个硬件起了很大帮助。本篇就带大家欣赏一下它的硬件设计。

一、硬件特性

1. Specifications

  • Communication: 10/100 Base-T Ethernet
  • Supports Protocol: Modbus/TCP, TCP/IP, UDP, HTTP, ICMP, DHCP and ARP
  • Supports Peer-to-Peer and GCL

2. Digital Input

  • Channels: 8
  • Dry Contact:
    Logic level 0: Open
    Logic level 1: Close to Ground
  • Wet Contact:
    Logic level 0: 0 ~ 3 VDC
    Logic level 1: 10 ~ 30 VDC
  • Supports 3 kHz counter input (32-bit with overflow flag)
  • Supports 3 kHz frequency input
  • Supports inverted DI status

3. Digital Output

  • Channels: 8
  • Source Type: 10 ~ 35 VDC, 1 A (per channel)
  • Supports 5 kHz pulse output
  • Supports high-to-low and low-to-high delay output

二、内部结构
