Associated with: Simatic S7 scanners
This status attribute shows the number of:
- Reads—Successful read operations
- Writes—Successful write operations
- Timeouts—Requests that did not receive a response within the expected time and therefore timed out. (The actual Timeout period is specified on the Channel Form.)
- CRCs—Cyclic Redundancy Check (CRC) errors
- Unknown—Any other errors
that have been detected on a scanner since that scanner was last restarted.
Example:
245 reads, 67 writes, 3 timeouts, 2 CRCs, 0 unknown
