FX3U-4DA (4-channel Analog Output)
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, 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".
