Error state
If at the input "GetValu" a HIGH-signal is present, the function block reads the last error states. If an error occurs during the reading process, "Error" is displayed at the output.
Signals
| Name | I/O | Type(s) | Function |
|---|---|---|---|
| GetValu | I | BIT | Activate reading |
| O | WORD | Access error | |
| Count | O | WORD | Number of states |
| State1 | O | STRING | State part 1 |
| State2 | O | STRING | State part 2 |
| BitSet | O | LONGLONG | State mask |
Parameters
The maximum number of readable states must be set using the function block (max 32/32 default).
Comments
"State1" and "State2" form a state string together. A STRING value represents a maximum of 17 characters. For this reason, longer strings will be split at a maximum of 2 STRING values. Any additional strings will be truncated.
