ARM BASED EFFICIENT INTERPRETER FOR SIMATIC S7 STATEMENT LIST

摘要

The international standard IEC61131-3 plays a significant role in the development of industry control system. As a core component of industry control system, it is a trend for programmable logic controller to support the standard. Based on an intermediate statement, this paper proposes a design of interpreter, and it provides a guideline for devising ARM based controllers which are compatible with IEC61131-3 programming languages. The construction of the interpreter is described in details by referring to SIMATIC S7 statement list of SIEMENS. And simulations have been done to verify the feasibility and efficiency of the interpreter.
