17. Sequences of the EN, Done, and Error flags: when an error occurs during communication (scenario 1) and when the
communication is compete (scenario 1).
Example 1: Read the parameter of Application Specific Tag on the first device of the first communication port.
1. Check HWCONFIG to learn the setting value in Application Specific Tag is "ABCDEFGH".
2. AS04SIL is the first module that installed on the right side of the PLC CPU. The setting value in Group is 0, and 1 in
both Module and Port.
3. We learnt that its index is 24, its Sub-index is 0, and the data type is StringT from its IODD file or the IO-Link device
manual. Set the setting values in Index to 24, in Sub-index to 0, in data type to 4 (StringT).
4. Start sending "to read" request when M0 is ON. When M10 (DONE) is ON, it indicates the device has responded
and has complete reading. ReadLen (D40) is 32, and the data string is stored in DataRead (D50~D65). IO-Link
device reads the data and stores it in accordance with the order of high byte and low byte.
