smartDEN IP-PLC - Ethernet I/O Relay Programmable Logic Controller

smartDEN IP-PLC is an Ethernet module (IP PLC controller) which can be used in a wide range of automation, remote monitoring, control, measurement and data-acquisition applications. Thank to its multi-channel design (8 digital inputs, 4 analog inputs, 4 temperature inputs, 8 SPDT relays and 2 analog outputs) this device can perform simultaneously a variety of measurement, control and automation functions. The built-in web interface allows users to configure the smartDEN IP-PLC, as well as to monitor/control input/output channels manually. smartDEN IP-PLC provides XML/JSON interface for integration with third-party developed applications. Supported by DRMv3.

In addition, smartDEN IP-PLC module can execute a custom program, written in a simple high-level language called DAEL. The program is composed directly from web browser and then checked and uploaded to the module. When started, the custom program is executed in parallel with the other functions and does not restrict any of them. Thus, the smartDEN IP-PLC module can work in standalone mode without need to be controlled by the network and solve more complex tasks like traffic lights control, PID controller, smart aquarium control, garage/barrier control, car park count and more.

smartDEN IP-PLC overview

DAEL script language

DAEL (Denkovi Assembly Electronics Langiage) is very simple language used especially for smartDEN IP-PLC programming. It is C like language and provides addition, substraction, multiplication and division. There are several variables predefined, comments and up to 10 000 symbols free program space which is more that enough for complex tasks.

Additionally the predefined variables can be accessed from HTTP GET requests which allows third-party applications to start/stop and control the custom DAEL program.

The DAEL lanuguage itself and some source code examples are detailed explained in the documentation.

// Example script for pulsing

// This example generates 10 pulses on Relay 1

REL1 = 0; // Initial Relay state - OFF

VAR_I1 = 0; // Initialization of the loop variable

while (VAR_I1 < 20) // Check the end condition

{

REL1 = 2; // Toggle the Relay state

delay(10); // Delay of 1 sec

VAR_I1 = VAR_I1 + 1; // Increment the loop variable

}

Access smartDEN IP-PLC from browser

The device has bult-in web server so you can access its resources from any modern web browser. The custom program edit/upload/debug is also done from the web server.

Access via software DRMv3

This device is supported by DRMv3 Software.

The device can be found in the device list under the default name: smartDEN IP-PLC

Access smartDEN IP-PLC from mobile devices

Android App DAE-aModules

Some useful information:

Select device smartDEN IP-PLC. Enter the IP address (URL), HTTP Port and web server main password for the device;

Control smartDEN IP-PLC I/O and program via JSON/XML/HTTP GET requests

It is possible to access not only the I/O lines via HTTP GET requests (current_state.xml / program.json) but also the DAEL custom program state and variables (/progra.xml / program.json). This is very suitable in cases where the program must be controlled from third party application / service. The returned reply is in XML or JSON format.

Troubleshooting

Problem: There is an access to the device via PING and Denkovi Finder "see" it, however it is not possible to open it's web server via any browser (the HTTP port is correct as well).
Solution: Some antivirus software (like Avast for example) may block the HTTP traffic to the device. Be sure this type of communication is enabled by your antivirus/firewall software.
