10 Programming Using IO-Link
10.2 Sample Program for Acquiring Service Data (Error Code)
10.2.1 Reading Error Codes
Error codes for the primary sensor receiver of the safety light curtain are acquired from the
service data that is acquired via IO-Link.
Index(Dec) Sub-Index(Dec) Stored information
81 0 Data length: 32 bytes (8 bytes x 4)
(Error code: Error codes are output in 8 bytes.
Primary sensor Starting from the leading byte,
receiver)
1 byte: Error code
4 bytes: Power-on time (counted every 15 minutes)
3 bytes: Query data
The four most recent error codes can be acquired.
When an SLC is not connected or there is no amount of
incident light, "0" is the error code.
