摘要

概述了设计实践，旨在通过局域网提高plc到显示面板的吞吐量，同时减少与plc的通信。网络活动减少的结果也将提高plc的扫描速度，plc必须做真正的工作。简要讨论了在中间设备中使用邮箱的普通技术，以及通过使用阶梯逻辑进行异常更新的技术。

LAN stress management

Design practices are outlined which are intended to improve the throughput from PLCs through LANs to display panels while decreasing communications to the PLCs. The result of less activity on the network will also boost the scan speed of the PLCs, which have to do the real work. Ordinary techniques of using mailboxes in an intermediate device, as well as updating by exception through the use of ladder logic, are briefly discussed.<>
