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
(Error code:
Primary sensor
receiver)
0 Data length: 32 bytes (8 bytes x 4)
Error codes are output in 8 bytes.
Starting from the leading byte,
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.
