Abstract
The present invention lowers possibility of producing a malfunction or an abnormity. A processor (2) receives a forwarding instruction of update data from an operation apparatus (10), determines whether the forwarding instruction is valid or invalid, and in a case in which the forwarding instruction is determined to be valid, forwards update data of a second memory (4) to a first memory (3) to update a user program.
Claims8
A programmable controller, comprising a processor, a first memory, and a second memory, wherein the first memory stores a user program, and the second memory stores update data of the user program and is built-in or removable, and
- the processor receives a forwarding instruction of the update data from an operation apparatus connected to the programmable controller, determines whether the forwarding instruction is valid or invalid, and when the forwarding instruction is determined to be valid, forwards the update data of the second memory to the first memory to update the user program.
A control program of a programmable controller, wherein the programmable controller comprises a processor, a first memory, and a second memory, the first memory stores a user program, the second memory stores update data of the user program and is built-in or removable, and the processor executes the control program of the programmable controller to perform the following steps:
- receiving a forwarding instruction of the update data from an operation apparatus connected to the programmable controller and determining whether the forwarding instruction is valid or invalid;
- and
- forwarding the update data of the second memory to the first memory to update the user program when the forwarding instruction is determined to be valid.
