5. Error messages during data transfer
If receiving an invalid data protocol from the PC (for example line not existing or letters where there should
be numbers) the counter
– provided it is still accessible - will return a corresponding error message. To be
able to do so, at least control character <STX> and identifier must be correct. If not, NE216 is no longer ac-
cessible and therefore not in a position to reply any error message to the PC.
In case no reply neither error message is replied on the PC request, it is a fatal error which means control
character <STX> and identifier are missing. Furthermore, PC and NE216 interface parameters are not con-
gruent. However these being correct, the failure is due to hardware or a defect in the data transmission line.
Standard structure in error messages:
<STX> Identifier line status <CAN> error number <ETX> <CR>
Example: Identifier =35, Line =09 (invalid line), error number =2
<STX>3509R<CAN>2<ETX><CR>
The error message replied will come without „line“ and „status“ information.
Detailed error description:
Error 1: Format error (incorrect <ETX> position. This signal is given in case
the data format was not kept during programming (for example during
parameterization of a limit only 4 digits instead of 5 have been
transferred).)
Error 2: Line (position) not existing or separating line
Error 3: Parameter error (invalid protocol data). Example: Scaling factor not
only comprising numbers but also of other characters not permitted, or
parameter beyond the permitted range.
