IO-Link Specifications
■Outline of IO-Link functions
〇
Communication Function
This product can check the pressure adjustment and diagnostic information using cyclic
data communication via the IO-Link system.
〇
Product status monitoring function
This function monitors the product status via the IO-Link communication.
- Multiple errors (e.g. internal hardware errors) can be detected.
- Multiple alarms can be detected (e.g., low pressure, over-voltage).
- Multiple notifications can be detected (e.g., specified operation cycle of the solenoid valve
has been reached).
- Multiple notification states (reaching the set accumulated energizing time) can be
detected.
〇
Output of fault status
The output status (Hold/Clear) when a communication error occurs can be set.
〇
Data storage function
The data storage function stores the IO-Link device parameter settings to the IO-Link
master.
With the IO-Link data storage function, the IO-link device can be replaced easily without
re-setting the equipment construction or setting parameters.
When the device parameters are set and downloaded to the device using the IO-Link setting
tool, the parameters in the downloaded device will be activated. After that, these parameters
are uploaded to the data storage in the master by stem command (back-up communication
command).
When the device is replaced with the same type of IO-Link device due to failure, the
parameter settings stored in the master are download automatically, device can be operated
with the parameter settings of the previous device.
Three levels of back up can be set for each port of the master device ("Disabled,"
"back-up/restore," and "restore").
"Back-up" implies the activation of upload and "restore" implies download.
