Main group 4/subgroup 8: Write R parameters in PLC signal bits
@482  <Value 1> <Value 2> <Value 3>  <Value>
The state of a flag bit in the PLC is loaded via a parameter, pointer or constant. 
The PLC number is specified by <Value 1>, the byte address by <Value 2> and the bit
address by <Value 3>.
Example:
@482    K1    K2    K0    K0 The state of the defined PLC flag bit is loaded with 0.
@483  <Value 1> <Value 2> <Value 3> <Value 4> <Value >
The state of a data word bit in the PLC is loaded via a parameter, pointer or constant.
The PLC number is defined by <Value 1>, the number of the DB or DX by <Value 2>,
the data word number by <Value 3> and the bit address by <Value 4>.
Example:
R60 = 1    R62 = 2    R63 = 4
@483   R60   R62   R63   K2   K1 The state of the defined PLC data word bit is loaded
with ”1”.

Main group 4/subgroup 9: Write R parameters in PLC signal bytes
@493  <Value 1> <Value 2> <Value>
The state of a flag byte in the PLC is loaded via a parameter, pointer or constant.
The PLC number is defined by <Value 1> and the byte address by <Value 2>.
Example:
@493   K1   K1   K01100111 The state of the defined PLC flag byte is loaded with the
constant.
@494  <Value 1> <Value 2> <Value 3> <Value>
The state of a data word left in the PLC is loaded via a parameter, pointer or constant.
The PLC number is defined by <Value 1>, the number of the DB or DX by <Value 2>
and the data word number by <Value 3>.
Example:
R53 = 10010110;
