*1. Completion of positioning
1) Operations turning the "positioning completion" bit ON.
2) When stopped at a STOP command
The "Positioning completion" bit does not turn ON at the target address.
*2. BFM #128 b11 and b12 are not available.
11.3.18 Error code [BFM #29, BFM #129]
If an error occurs, the error code is stored.
1. Buffer memories to store error information
If an error occurs, the buffer memories store error information as shown in the table below.
After removing the cause of the error, the system can recover from the error by an error reset command.
2. Error codes
Error codes are stored in decimal format.
