11.6 Data transfer: System memory into R parameter
Main group 3/subgroup 8: Read PLC signal bits in R parameters
@380 <Var> <Value 1> <Value 2> <Value 3>
The state of an input bit in the PLC is read in the parameter defined with <Var>. The
PLC number is defined by <Value 1>, the byte address by <Value 2> and the bit
address by <Value 3>.
Example:
@380 R50 K1 K2
@381 <Var> <Value 1> <Value 2> <Value 3>
The state of an output bit in the PLC is read in the parameter defined with <Var>. The
PLC number is defined by <Value 1>, the byte address by <Value 2> and the bit
address by <Value 3>.
@382 <Var> <Value 1> <Value 2> <Value 3>
The state of a flag bit in the PLC is read in the parameter defined with <Var>. The PLC
number is defined by <Value 1>, the byte address by <Value 2> and the bit address by
<Value 3>.
@383 <Var> <Value 1> <Value 2> <Value 3>
The state of a PLC data word bit is read in the parameter defined with <Var>. 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:
@383 R51 K1
Main group 3/subgroup 9: Read PLC signal bytes in R parameters
@390 <Var> <Value 1> <Value 2>
The state of an input byte in the PLC is read in the parameter defined with <Var>. The
PLC number is defined by <Value 1> and the byte address by <Value 2>.
Example:
@390 R52 K1 K1
11–20
K0 The state of the defined input bit is read in R50.
K2 K4 K2 The state of the defined PLC data word bit is
read in R51.
The state of the defined PLC input byte is read in R52.
