Sequence Basic Instructions

These basic instructions perform bit unit logic operations and are the basis of the relay
sequence circuit.
As shown in the illustration below, this is expressed by the combination of the relay coil
and contact.
There are several relay types which are explained in "Section 1.2", and the relay which
can be specified depends on the instruction. Refer to the explanation of each instruction.
Example:
Start (ST) instruction
Read the on or off status of the specified contact.
Out (OT) instruction
Output the operation result to the specified coil.
