Cautions
• The FLWR instruction is completed abnormally if a CompactFlash
• The user should pay close attention to the number of times data is written when the writing destination is set to the
TM
CompactFlash
For example, if data is written to the CompactFlash
approximately 2 months.
• Even if the writing destination is set to the buffer inside the CF-ADP, data is written to the CompactFlash
the case of overwriting.
• The FLWR instruction writes data to the CompactFlash
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
is set to anything other than bit type. When a word device is specified in
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)"/"IVCK (FNC270) to IVMC (FNC275)" instruction and an
"FLCRT (FNC300) to FLSTRD (FNC305)" instruction for the same port.
File ID : K0 to K63
Head of devices which store data to be written.
Specify the head of devices which store the data to be written to the CompactFlash
card.
Specify the data writing type
K0 : Mixed type
K1 : Bit type
K2 : Decimal type (16-bit)
K3 : Decimal type (32-bit)
K4 : Hexadecimal type (16-bit)
K5 : Hexadecimal type (32-bit)
K6 : Real numbers(Floating point data) Exponent expression type (32-bit)
K7 : Character string (512 half-width/full-width characters maximum)
K8 : Data name : Character string consisting of up to 32 half-width/full-width
characters. Index, DATE TIME are added automatically.
Specify the line position of the writing destination, or specify additional writing.
Line position of the writing destination : K1 to specified maximum number of lines
Additional writing : K-1
Specify the data column position in the writing destination.
Column position : K1 to K254
Additional writing : K-1
Number of written data points : K1 to K254
Writing destination
TM
K0 : CompactFlash card
K1 : Buffer inside the CF-ADP
Line position after writing : K1 to specified maximum number of lines
Column position after writing : K1 to K254
Channel number used by the CF-ADP
K1 : ch1
K2 : ch2
card because data is written every time the FLWR instruction is executed.
