*1 Those values show example when the error occurs at 10:35:40, August 29th, 2012.
*2 The clock information of the error that occurred is based on the clock information acquired from the CPU module of the master station.
When an error has occurred before the clock information is acquired from the CPU module, the error time is not recorded.
It is stored in the same format as Current error data 2 to Current error data 16 (address: 2B10H to 2BFFH) and Current error
data 1 (address: 2B00H to 2B0FH).
For the error code, refer to the following.

■Storage order of error data
The latest error is stored in Current error data 1 (address: 2B00H to 2B0FH).
Errors that occurred up to this time are stored in Current error data 2 to Current error data 16 (address: 2B10H to 2BFFH) in
reverse chronological order.
When 15 minor and moderate errors are stored in Current error data, new minor and moderate errors that
occur are stored in the IO-Link module.
When 15 minor and moderate errors are stored, even if one error is eliminated, the minor and moderate errors
saved inside the IO-Link module are stored.
If the same cause of errors occur continuously, only the error that occurred first is stored.
Also, new errors that occur after a major error are not held.
