A Symbol Can be used for an Array

 

Variable Subscript.

NEW

A physical address or symbol can be specifi ed for an array subscript, so data can be dynamically specifi ed.

Example Data[i]: An element number is indirectly specifi ed by the value of symbol i. If the value of symbol i is &5, data[5] is specifi ed

for element number 5.

New instructions such as tracking, sorting, and fl oating-point decimal maximum/minimum value search instructions are supported.

Up to 128 Cyclic Tasks

are Supported.4

Times NEW

More than before

The user program can be divided into up to 128 tasks. Using smaller task programs makes it easier to structure programs. This also contributes to shorter cycle times by controlling the tasks that are being executed or not executed in smaller units.

Languages Conforming to IEC Are Supported.

Ladder diagrams and ST languages can be freely combined and made into components as function blocks (FBs), allowing programs to be created in the optimum language for the particular process.

The Number of Communications Logic

 

Ports has Increased to 64.
