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 K0 The state of the defined input bit is read in R50.
@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 K2 K4 K2 The state of the defined PLC data word bit is
read in R51.
