摘要
详细介绍了可编程控制器智能扩展模块S1000-EX的软硬件设计思路,并给出了设计框图。整个系统以单片机为核心,通过可编程逻辑电路实现逻辑控制,再配以模块化软件设计,构成一个完整的多功能扩展模块。本模块经过测试,工作稳定,性能优良,满足了小型可编程控制器功能扩展的需求。
With SIO00-EX intelligence-extended module as an example, the design idea of intelligence-extended module is introduced in detail and its block diagram is given. The whole system takes a single-chip computer as its core, in which logic controls are realized through a programmable logic circuit, and with modular software design an integrated multifunctional intelli- gence-extended module is constituted. Testing this module show that its operation is stable with good performances, the needs of small sized PLC for function extension are met.
