8.4 Program to Initialize FX3U-4DA (Factory Default)
8.4 Program to Initialize FX3U-4DA (Factory Default)
To initialize FX3U-4DA, execute the following program.
This will return the output mode (BFM#0), the offset data (BFM#10 to #13) and the gain data (BFM#14 to #17)
will be to the factory default status state.
1. Conditions
The sequence program described in this section is under the following conditions.
1) System configuration
FX
3U-4DA (unit No.0) should be connected to the FX3U Series PLC.
2) Device assignment
2. Example of sequence program
•For FX3U/FX3UC Series PLCs
•For FX
3G/FX3GC/FX3U/FX3UC Series PLCs
3. Cautions regarding initializing
• During initialization, output is stopped, and H0000 is automatically written in the output status (BFM#6).
At the completion of initialization, the output status (BFM#6) will automatically change to H1111, and the
output will be restarted.
• It takes approximately 5 seconds to complete initialization. Do not set (write) data in the buffer memory
during the period.
• Priority is given to the setting of the change prohibition mode (BFM#19).
• Once initialization is completed, the value in BFM#20 will automatically change to "K0".
