摘要
本文阐述了一种多工位定位系统在横移车中的应用,该定位系统采用8421码的编码方式,给每个工位设定一个8421码的编码值,当工位检测开关输入给可编程控制器(PLC)的开关量信号通断组合与设定的8421码一致时,横移车在该工位定位。
The application of a kind of multi-station positioning system in the pipe transverse carriage has been introduced in the text.The positioning system adopts 8421 codes coding mode and gives each station a set 8421 codes coding value.The pipe transverse carriage has been located at the station when the switching on ＆ off combination signal input to the programmable controller （PLC） detected by each station detection switch is in accordance with the set 8421 codes.
