Problems solved by technology

This is because, needless to say, the processing of the I / O control function is not performed while the processing of the HMI function is being executed, and therefore when the processing time of the HMI function is long, an obstacle occurs in the I / O control.

Embodiment Construction

[0049] Embodiments of the present invention will be described below with reference to the drawings.

[0050] figure 1 It is the functional structure diagram of the programmable display with I / O control function in this example.

[0051] First, as a premise, the programmable display 10 with an I / O control function of this example is a programmable display provided with not only the said HMI function but also the said I / O control function as demonstrated in the said background art. That is, it has the HMI function 15 and the I / O control function 16 shown in the figure.

[0052] In addition, the HMI function and the I / O control function have already been described in the background art, and the description here is omitted. The control function 16 is a function of PLC. The I / O control function 16 is realized, for example, by a CPU or the like not shown executing a sequence program for I / O control not shown. The HMI function 15 is, for example, a function to display the above-...

Abstract

The programmable display with I / O control function of the present invention and the control system automatically determine an appropriate ratio of processing time between the HMI function and the I / O control function of each screen. The cycle time acquisition unit (12) operates only the HMI function (15) to obtain the cycle time for each HMI screen. The scan time acquiring unit (13) operates only the I / O control function (16) to obtain the scan time. The switching ratio determination unit (14) calculates the "ratio of the processing time of the HMI function (15) and the I / O control function (16)" (ratio) for each HMI screen based on the cycle time, scan time, and switching ratio definition information .

Description

technical field [0001] The invention relates to a programmable display with I / O (input / output) control function. Background technique [0002] Conventionally, the programmable display generally displays the screen (the screen for HMI; the operation display screen) which displays the state of PLC main body and the external connection device, etc. Such a screen is displayed based on data called screen data or the like. The user sees the display to grasp the state of the externally connected device, or operates switches, buttons, and the like on the operation display screen. For example, the programmable display performs the following processing: accessing the memory of the PLC main body and temperature control device at a fixed cycle to obtain data (measurement data of various sensors, etc.), and displaying the data as various items (item ). Moreover, a programmable display executes the process corresponding to the switch, button, etc. operated by the said user. Such a fun...
