Yes! A smartphone can monitor
and control the ESP8266 along with the OP320 HMI panel through
the RemoteXY's IoT cloud server. First, set the required RemoteXY
web interface configuration. Select the cloud server connection and
then the ESP8266 NodeMCU board type. The Wi-Fi on chip module and FLProg IDE. You can create a new cloud server token
from here or use an existing token. Be sure to take note of the server’s
name, port number, and token. Drag two button controls into the interface. Change the first color to
green, and the caption to ON. Change the other color to
red and its caption to OFF. Drag in the LED and the online graph
indicators and adjust them as required. Also, place the edit field here, adjust as
required, and change the input type to integer. Then click on Get Source Code
and copy the code from here. From the number 7 video of the ESP8266 PLC
Ladder Logic series, expand the controller, the Wi-Fi module settings, and
double-click to enable the Wi-Fi client. Input your home network's SSID and password. Insert a new project board above the existing
one and insert the RemoteXY block into it. Double-click on it and select
the inputs/outputs tab. Click on download description and
paste the RemoteXY source code. On the communication module tab, observe
that cloud server mode has been selected. The server’s name, token, and port number were
all retrieved from the RemoteXY source code. Connect the A0 analog input to
the RemoteXY onlinegraph_1 input, and the KP1 contact to the led_1 input. Connect the K1 and K2 coils to the
RemoteXY button_1 and button_2 outputs. For the edit_1 output, place the SERVO Modbus tag
here and select the input of the write enable. Place a number change block and draw
connections to the blocks as shown. Drag and connect K1 and K2 contacts to
the inputs of the bistable relay as shown. Then compile the project. In the Arduino IDE, locate the dot attach line
in the void setup section of the code and input comma 544 comma 2400 for the servo motor.
Then compile and upload the Arduino code. Connect your smartphone to
your home Wi-Fi network, open the RemoteXY app, and
add a new cloud server device. Input the RemoteXY cloud server’s name, port
number, and token, and connect to the ESP8266. Observe the Potentiometer values on the
online graph as in the OP320 HMI panel. Hold down the ON button on the app to turn
on the LED and the OFF button to turn it off. You can also adjust the servo
position in the edit field. All of these can also be monitored
and adjusted from the OP320 HMI panel. Now, you can monitor and control your
ESP8266 device from anywhere in the world through the RemoteXY IoT Cloud Server. Thanks for watching.
