5.4.19 BFM #61: Error status data automatic transfer-to data register specification

Use this function to automatically transfer the error status data (BFM #29) to the data register specified in
BFM #61.
When an error is detected, data will be automatically transferred from FX
the PLC does not need a program for reading data, and the scan time of the PLC can be shortened.
1. If "BFM #61 = K200 (initial value)"
Specified data
register
D200
2. Cautions regarding error status automatic transfer function setting
• If a data is already specified for the other automatic transfer functions, do not specify the same data
register.
• This function is valid by turning on b0 of the status automatic transfer function setting (BFM #60).
• When a value out of the above setting range is set, b9 of the error status BFM #29 is turned on.
• The data set in BFM #61 will be retained in the EEPROM.
3. Cautions regarding EEPROM writing
If data is set in BFM #0, #5, #10 to #17, #32 to #35, #50 to #54 or #60 to #63, the data will be written in the
EEPROM of FX
3U
Do not turn off the power immediately after writing values in these buffer memories.
The maximum number of EEPROM rewritable times is 10,000. Therefore, when creating a program, do not
frequently write data in the above buffer memories (BFM).
→ For a detailed description of the error status (BFM #29), refer to Subsection 5.4.12.
