  The present invention has been made to solve the above-described problems. In a remote monitoring system using a portable terminal such as a tablet type, it is not necessary to create a dedicated screen for a portable terminal, and the entire screen is displayed. However, it is an object to obtain a terminal and a terminal program that can eliminate erroneous operation of symbols.

The terminal according to the present invention is:
In a terminal that can display a field device and the state of the device on a screen as symbols and can be operated by a user touching the symbol on the screen,
The terminal includes a screen information recording unit for recording symbol information to be displayed on the terminal and coordinate information of the symbol, and an operation information recording unit for recording various operation modes on the screen and processing contents for the various operation modes. And
The operation processing function of the terminal is
A mode of operation performed on the screen performed by the user, and an operation detection unit that detects the symbols arranged within a certain range from the coordinates on the screen targeted for the operation;
A process determination unit that determines whether or not the process corresponding to the symbol can be executed according to the detected size of the symbol;
The drawing function of the terminal is a symbol that expands the size of the symbol until the determination of the process determination unit becomes “Yes” when the process determination unit determines “No” to execute the process assigned to the symbol. A display size management unit is included.

The terminal program according to the present invention is
In a terminal program that displays field devices and the state of the devices on a screen as symbols, and can be operated by a user touching the symbols on the screen,
Detecting coordinate information on the screen and an operation action by the user from the operation on the screen by the user;
Step S003 for determining whether or not the operation action is related to the symbol;
If the operation action relates to the symbol, step S004 for extracting information of the symbol within a certain range from the coordinate information;
Step S005 for obtaining the size of the symbol extracted in Step S004;
If the result of step S005 is that the size is less than the size that allows execution of the process corresponding to the symbol, step S007 expands only the symbol to a size that allows execution of the process corresponding to the symbol; ,
As a result of step S005, when the size is equal to or larger than the size that allows execution of the process corresponding to the symbol, the process corresponding to the operation action is executed.

  Since the terminal and the terminal program according to the present invention are configured as described above, when the symbol to be operated is small, the operation is performed after the enlarged display. It is possible to prevent erroneous operations due to mistakes, push mistakes, and the like.
