What is IO-Link?
IO-Link is an open, standardized technology that allows users to set up point-to-point connections. It eliminates the need to address sensors. IO-Link supported components are compatible with each oth
IO-Link is a fieldbus?
IO-Link is not a fieldbus. In the automation architecture, IO-Link lies below the fieldbus topology. The IO-Link master identity acts as a protocol conversion gateway for connecting sensors to the fie
What is an IO-Link master?
The IO-Link master is used to establish a connection between one or more IO-Link devices and the fieldbus system, acting as a gateway.
IO-Link configurable DI/DO slave module, how to define each point as output mode or input mode?
The default factory setting of each IO point is input mode, which needs to be configured with the help of PCT tool or program function block.
IO-Link M12 Hub module, how are the signal points of each M12 port distributed?
Each M12 port includes Pin2 and Pin4, two signal points, which are in different bytes. In the Siemens system, Pin4 is in the low byte and Pin2 is in the high byte.
In Japanese PLCs (Mitsubishi, Omron, Keyence), why does the data collected by the IO-Link analog input Hub module fluctuate greatly?
In Japanese PLC, the data type of "word", the high and low bytes are inverted. When using, the real value should be obtained after adjusting the low bytes.
In Siemens PLC configuration, how to select the appropriate number of device bytes for the slot configuration of the IO-Link master ?
The number of bytes occupied by different IO-Link Hub must be configured according to the number of input and output bytes specified in the user manual or selection manual.
How to change the IP address of the module when using Profinet communication protocol?
When using this protocol for communication, the IP address of the module is assigned by the PLC or controller configuration and cannot be set using tools such as PCT.
The IO-Link master module requires EtherNET IP communication. How to switch the protocol?
The multi-protocol module defaults to Profinet. If you need to switch protocols, please refer to the steps in the manual. When using the dialing method, please note that each adjustment of the dialing
The IO-Link valve island only has 4 valves installed and is configured with 1 byte output. Why does the IO-Link master report an error?
No matter how many valve plates are installed in the IO-Link valve island, it should be configured with 6-byte output, or a higher number of bytes.
