    摘要： An integrated RISC and relay ladder logic processor uses shared registers, program counter, bus lines, and processing circuitry to eliminate delays associated with transfer of control in co-processor type architecture. The RISC instructions do not significantly interfere with the specialized hardware needed for rapid relay logic execution, the latter which may be further improved through the use of a pipeline well suited for relay ladder logic which creates few pipeline hazards. Two levels of condition codes are used for the arithmetic and logic instructions to permit nested arithmetic operations without interference with those instructions visible to the user. Hybrid instructions are provided to synchronize the relay ladder instructions with the arithmetic instructions, thus truly integrating the two instruction sets.

    摘要： A method of handling a fault which occurs during execution of an executable program comprises the steps of designating a first sequence of instructions of the executable program as visible and designating a second sequence of instructions of the executable program as invisible. According to this scheme, for the first visible sequence of instructions, faults are reported in a manner which designates an instruction at which the fault occurred. For the second invisible sequence of instructions, faults are reported in a manner which designates the invisible sequence of instructions as a whole. The invention permits fault handling for instructions added by a user to be performed in the same way as fault handling for built-in functions, and is usable with compiled machines.

    摘要： A compiler for an industrial controller uses a user modifiable instruction table to contain code fragments necessary to compile particular instructions. During compilation, the instructions are replaced with the code fragments. Thus new instructions recognizable by the compiler may be added simply by editing this instruction table. Multiple instructions having the same name are resolved through a best match of operand types which examines the possible data loss in conversion of operand types to select a particular one of the instructions.

    摘要： The subject invention relates to systems and methods that facilitate motion between different coordinate systems in an industrial control environment. The systems and methods accept data in one coordinate system and transform the data to a different coordinate system. Suitable transformations include instructions that transform between Cartesian, pre-defined non-Cartesian, and user-defined non-Cartesian coordinate systems, including transformations between a non-Cartesian coordinate system to another non-Cartesian coordinate system. Such transformations can be programmed in essentially any industrial control language and can be seamlessly integrated with the control environment. The systems and methods can be utilized to generate a motion instruction that includes, among other information, source and target coordinate systems and the transformation between them. The subject invention provides for connecting various systems together through respective motion instructions, wherein a motion of a source system is mapped to a coordinate system of a target system and the target system is moved accordingly.

    摘要： A machine is operated by a programmable controller that executes a ladder logic control program. A custom ladder logic processor is provided for high speed execution of the more common ladder logic instructions and a microprocessor interprets the remaining ladder logic instructions. A first section of memory contains a ladder logic control program in which some of the instructions are macro instructions executable by the ladder logic processor. Each macro instruction specifies an operation code, a first memory file containing data to be processed by the macro instruction, a second memory file containing control data governing the processing, and a storage location for results produced by execution of the macro instruction. Another memory section stores a library file containing a ladder logic software routine for each macro instruction, and stores a directory which identifies a starting location of the macro instruction routine for each operation code. When a macro instruction is encountered in the control program, the corresponding ladder logic software routine is executed. During the execution of the routine data is obtained from the first memory file and the results are placed in the storage location. At the completion of the ladder logic software routine, execution of the control program resumes.
