Processing details
■FLT
• Converts 16-bit BIN data designated by (S) to 32-bit floating decimal point type real number, and stores at device number
designated by (D).
• BIN values between -32768 to 32767 can be designated by (S).
■DFLT
• Converts 32-bit BIN data designated by (S) to 32-bit floating decimal point type real number, and stores at device number
designated by (D).
• BIN values between -2147483648 to 2147483647 can be designated by (S)+1 and (S).
• Basic model QCPU: The serial number (first five digits) is "04122" or later.
(S): Integer data to be converted to 32-bit floating decimal point data or head number of the devices where the integer data is stored (BIN 16/32 bits)
(D): Head number of the devices where the converted 32-bit floating decimal point data will be stored (real number)
(D): Head number of the devices where the converted 32-bit floating decimal point data will be stored (real number)
