List of instructions
An instruction list is given in the sequence of ladder diagram instructions
and SFC instructions on the next page and thereafter.
The groups in the list correspond to the group classifications of function
instructions adopted by the programmer (T-PDS). (Except for SFC).
The required numbers of steps signify the size of memory required for
storing these instructions. The showing of the required number of steps
by a range such as 4-7, is because the number of steps changes due to
the following conditions, even for the same instruction.
● When using digit designation, there is an increase of 1 step per 1
operand.
● When a constant is used in a double-length operand, there is an
increase of 1 step.
● When executing index modification in a constant, there is an increase
of 1 step.
Here, an overview of each instruction is given. See the instruction
manual in a separate volume for details.
The execution time shows the required time when the T2N fetches the
instruction on memory and performs required operation.
The execution time shown on the next page and thereafter is normal
case value. i.e. when no index modification, no digit designation and
normal registers are used for each operand.
The execution time is subject to increase due to using index
modification, digit designation, direct input register/device (IW/I), direct
output register/device (OW/O) for each operand.
