34 FX3U-CF-ADP Applied Instructions – FNC300 to FNC305

Details on the setting data in the FLWR instruction are as shown below.

• The FLWR instruction is completed abnormally if a CompactFlash

TM

 card is not mounted.

• The user should pay close attention to the number of times data is written when the writing destination is set to the 

CompactFlash

TM

 card because data is written every time the FLWR instruction is executed.

For example, if data is written to the CompactFlash

TM

 card every one minute, data is written 100,000 times in 

approximately 2 months.

• Even if the writing destination is set to the buffer inside the CF-ADP, data is written to the CompactFlash

TM

 card in 

the case of overwriting.

• The FLWR instruction writes data to the CompactFlash

TM

 card after the internal buffer inside the CF-ADP becomes 

full when the writing destination is set to the buffer. Data stored in the internal buffer inside the CF-ADP is erased 

when a (instantaneous or long) power interruption occurs.

• When the data type is a data name (K8), the user can specify only the head line position before writing other data. 

Index and DATE TIME are added automatically.

• The FLWR instruction may require several scans to acquire data. Take proper measures such as saving acquired 

data in another device if data consistency is required.

• It is necessary to set the device number in multiples of 16 when a bit device is specified in 

 

and the data type 

is set to anything other than bit type. When a word device is specified in 

 and the data type is set to bit, the 

FLWR instruction acquires data to be written from the least significant bit of the specified device.

• When 

 is "K7" or "K8", 00H, which indicates the end of the string, must be added to the end of the character 

string.

• It is not permitted to use an "RS (FNC 80)/RS2 (FNC 87)"/"ADPRW (FNC276)"/"IVCK (FNC270) to IVMC 

(FNC275)" instruction and an "FLCRT (FNC300) to FLSTRD (FNC305)" instruction for the same port.
