Here, a case will be described in which the operation of the device 32 is confirmed from the I/O module 10 by an operator operation in the mobile terminal 20. Note that the operation of the device 32 is also confirmed by the operator operation detected by the operation input unit 14, as in fig. 3, and the description thereof is omitted.
First, when the program 24P is started in the mobile terminal 20 and the target device 32 to be checked for operation is selected in accordance with the device selection operation performed by the operator (step S100), the terminal control unit 25 of the mobile terminal 20 generates an operation state acquisition request (message) for acquiring an operation state of the target device 32 based on the setting data 24A and transmits the operation state acquisition request from the wireless I/F unit 21 to the I/O module 10 (step S101).
When receiving the operation state acquisition request from the mobile terminal 20 via the wireless I/F unit 13, the operation confirmation unit 18 of the I/O module 10 generates an operation state acquisition request signal (I/O signal) based on the device data 16A of the specified target device 32 (step S102), and transmits the operation state acquisition request signal from the device I/F unit 12 to the target device 32 (step S103).
The target device 32 acquires its own operating state based on the operating state acquisition request signal from the I/O module 10 (step S110), and sends back an operating state acquisition response signal (I/O signal) including the acquired operating state to the I/O module 10 (step S111).
The operation confirmation unit 18 of the I/O module 10 generates an operation state acquisition response (message) including the operation state of the target device 32 based on the operation state acquisition response signal from the target device 32 (step S112), and transmits the operation state acquisition response (message) from the wireless I/F unit 13 to the mobile terminal 20 (step S113).
The terminal control unit 25 of the mobile terminal 20 extracts the operating state of the target device 32 included in the operating state acquisition response based on the operating state acquisition response from the I/O module 10 received via the wireless I/F unit 13, and displays the operating state on the screen display unit 23 (step S114). This enables the operator to confirm the operation state of the target device 32 before the operation confirmation.
Next, the terminal control unit 25 of the mobile terminal 20 sets parameters related to the operation confirmation of the target device 32 in accordance with the parameter setting operation by the operator (step S120), generates an operation confirmation request (message) requesting the operation confirmation of the target device 32 based on the set parameters in accordance with the subsequent operation confirmation request operation by the operator (step S121), and transmits the operation confirmation request (message) from the wireless I/F unit 21 to the I/O module 10 (step S122).
When receiving the operation confirmation request from the mobile terminal 20 via the wireless I/F unit 13, the operation confirmation unit 18 of the I/O module 10 generates an operation confirmation request signal (I/O signal) based on the device data 16A of the specified target device 32 and the parameter included in the operation confirmation request (step S123), and transmits the operation confirmation request signal from the device I/F unit 12 to the target device 32 (step S124).
The target device 32 controls its operation state to a specified state in response to the operation confirmation request signal from the I/O module 10 (step S125).
Thereafter, the target device 32 acquires its own operation state (step S130), and sends back an operation confirmation result signal (I/O signal) including the acquired operation state to the I/O module 10 (step S131).
The operation confirmation unit 18 of the I/O module 10 generates an operation confirmation result (message) including the operation state of the target device 32 based on the operation confirmation result signal from the target device 32 (step S132), and transmits the operation confirmation result (message) from the wireless I/F unit 13 to the mobile terminal 20 (step S133).
The terminal control unit 25 of the mobile terminal 20 extracts the operation confirmation result of the target device 32 included in the operation state result based on the operation confirmation result from the I/O module 10 received via the wireless I/F unit 13, and displays the operation confirmation result on the screen display unit 23 (step S134). Fig. 4 is a screen display example of the mobile terminal. Fig. 5 shows an example of screen display of the mobile terminal (next). This enables the operator to confirm the result of the action confirmation on the target device 32.
[ Effect of the present embodiment ]
In this way, in the present embodiment, the operation confirmation unit 18 of the I/O module 10 confirms the operation of the designated target device 32 among the plurality of devices 32, based on the input operation confirmation instruction.
More specifically, the I/O module 10 further includes a wireless I/F unit 13 that performs wireless communication with the mobile terminal 20, and the operation confirmation unit 18 confirms the operation of the target device 32 based on an operation confirmation instruction received from the mobile terminal 20 via the wireless I/F unit 13.
Thus, the I/O module 10 can check the operation of the target device 32 independently of the controller 31. Therefore, even when the operator different from the controller 31 sets the equipment 32 on the power control panel 30 before the controller 31, the operator can immediately check the operation of the equipment 32.
Therefore, the degree of freedom in the setting timing of the controller 31 and the plant 32 is increased, and the setting process can be smoothly performed.
In addition, according to the present embodiment, since the controller 31 and the I/O module 10 can be connected by the communication cable 31L, it is not necessary to lead the I/O cable 32D of each device 32 to the controller 31. Therefore, the wiring work on the power control board 30 can be significantly reduced. In addition, the number of terminals of terminal blocks 31T and 32T can be significantly reduced, and the installation area required for control side panel 31P and power side panel 32P can be reduced. Further, the control side panel 31P can be shared among the control systems, and the work of designing the control side panel 31P can be omitted, so that the budget reduction and the construction period reduction can be achieved in connection with the installation of the control systems.
