Abstract
A programmable logic controller (10) is connected to external equipment (40) through a serial communication unit (30), and the programmable logic controller (10) includes: a memory (7), including a user program (11) and a setting document (13), where the user program (11) records both of a command for the communication interface device and command target information thereof, and the setting document (13) saves address information corresponding to the command target information; and a processor (8), reading the user program (11) and the setting document (13) to execute the command.
Claims9
A programmable logic controller, connected to external equipment through a communication interface device, and the programmable logic controller comprising:
- a memory, containing a user program and a setting document, wherein the user program records both of a command for the communication interface device and command target information thereof, and the setting document saves address information corresponding to the command target information;
- and
- a processor, reading the user program and the setting document to execute the command for the communication interface device.
A control method of a programmable logic controller, wherein the programmable logic controller is connected to external equipment through a communication interface device, the control method of the programmable logic controller comprising:
- a step of reading a user program and a setting document, wherein the user program records both of a command for the communication interface device and command target information thereof, and the setting document saves address information corresponding to the command target information;
- and
- steps of processing the command for the communication interface device.
A control program of a programmable logic controller, wherein the programmable logic controller comprises a processor and is connected to external equipment through a communication interface device, the control program of the programmable logic controller comprising:
- making the processor to execute a step of reading a user program and a setting document, wherein the user program records both of a command for the communication interface device and command target information thereof, and the setting document saves address information corresponding to the command target information;
- and
- steps of processing the command for the communication interface device.
