Syntax: = Q 5.2
The content of the RLO is copied to the specified bit operand. After an assignment a new linking chain is started, that means the first operation after a ‘=‘ always gives the value of an operand, indifferent, whether the operation is named ‘A’. ‘O’ or ‘X’. The operations ‘AN’, ‘ON’ and ‘XN’ however load the RLO with the negated value of the operand.
FBD
The result of the precede logic operation is copied to the specified operand. The assignment block is usually created automatically. But you can also call the list and ‘= select assignment’.
You can change the ‘=‘ sign to ‘S’ or ‘R’ by the space bar or by ‘Shift-ArrowRight’. To do so the yellow cursor has to stand on the block.
LAD
In LAD the assignment is usually named ‘coil’. The coil will be switched on if current flows through it. Usually the coil is created automatically. But you can also call the list and ‘= select assignment’.
You can change the ‘-( )-’ sign to ‘-(S)-’ or ‘-(R)’by the space bar or by ‘Shift-ArrowRight’. To do so the yellow cursor has to stand on the block.
