What is IO-Link?
IO-Link is an open, standardized technology that allows users to set up point-to-point connections。It does not need to address the sensor。IO-Link components are compatible with each other。
IO-Link is a field bus?
IO-Link is not a fieldbus。In an automation architecture, IO-Link is located below the fieldbus topology。IO-Link主站身份如同一个协议转换网关,用于将传感器连接至现场总线和相连的控制器。
What is the IO-Link master station?
IO-Link主站用于建立1个或多个IO-Link设备与现场总线系统的连接,起到网关的作用。
IO-Link configurable DI/DO slave module, how to define each point as output mode or input mode?
The default factory setting for each IO is input mode, which needs to be configured by PCT tools or program function blocks。
IO-Link M12 slave module, how are the signal points distributed for each M12 port?
每个M12端口,包含Pin2与Pin4,两个信号点,分别在不同字节里,西门子系统中Pin4在低字节,Pin2在高字节。
在日系PLC中(三菱、欧姆龙、基恩士),IO-Link 模拟量输入从站模块,采集到的数据为什么波动很大?
日系PLC中,“字”的数据类型,高低字节是反的,使用时,应对调高低字节后,才是真实值。
In Siemens PLC configuration, slot configuration of IO-Link master station, how to choose the appropriate number of device bytes?
不同的IO-Link Secondary station,占的字节数需根据使用手册或选型手册中规定的输入输出字节数进行配置。
How to change the IP address of the module when Profinet communication protocol?
在使用该协议通讯时,模块的IP地址是由PLC或控制器组态分配,使用PCT等工具无法进行设置。
IO-Link master station module needs EtherNET IP communication, how to switch protocols?
multi-protocol模块出厂默认Profinet,需要切换协议应参考手册中的步骤进行,采用拨码方式时,注意每次调整拨码,都在模块下次上电时生效。
IO-Link阀岛,只安装了4片阀,配置了1个字节输出,为何IO-Link主站会报错?
The IO-Link valve island should be configured with a 6-byte output, or higher, regardless of the number of valves installed。
