As one of Lumitio’s goals with the Legacy Connector Framework is to facilitate the integration of protocols with 0 programming.
We chose to base our Visual Programming on Node-RED. Originally developed by IBM. You can read more about Nored-RED, click here.
Lumitio has developed a series of Nodes to take advantage of the features provided by the Legacy Connector Framework, always trying to minimize the need for programming.
With the Nodes developed by Lumitio it becomes possible to do real time data processing before being sent to the cloud.
Step 1. Login to enable deploy and edit mode
The default access credentials:
| Username: | admin |
| Password: | adminadmin |
Step 2. Choose a Node from Lumitio palette
| S7 Ethernet | Read/Write to Siemens – 300/400/1200/1500 |
| S7 MPI DP | Read/Write to Siemens MPI |
| Melsec | Read/Write to Mitsubishi – Types A/QnA/Q/L/R |
| Omron | Read/Write Omron Ethernet FINS – CV/CP/CS/CJ/NJ/NX |
| Cloud connector | Send data to the Cloud |
| Lora Server | Read data from LoraWan Devices |
| Cloud to GPIO | Write messages to GPIO |
| Cloud to S7 Ethernet | Write messages to S7 Ethernet node |
| Cloud to Virtual | Write messages to Virtual Interface node |
| Cloud to Modbus | Writes messages to Modbus node |
| GPIO | Read GPIO |
| Modbus Master/Slave | Read/Write Modbus RTU/TCP |
| Virtual | Virtual Interfaces |
Step 3. Connection tab
Depending the Node you choose, the Connection tab changes.
Step 4. Variables tab
| Address | Protocol dependent |
| Name | Variable name |
| Variation | All – send all readings DIFF – Only send if new reading is different from last reading 0.2 – Only send if new reading >= 0.2 from last reading 0.5 – Only send if new reading >= 0.5 from last reading 1 – Only send if new reading >= 1 from last reading 1.5 – Only send if new reading >= 1.5 from last reading 2 – Only send if new reading >= 2 from last reading 10 – Only send if new reading >= 10 from last reading Virtual – Don’t send readings. Available only locally |
| Interface type | READ/WRITE – Variable R/W READ – Variable R WRITE – Variable W |
| Variable type | Average Value – Send average reading every 5min Raw Value – Send all readings Accumulated Value – Send accumulated reading every 5min Control (Bool) Control (Numeric) |
| Category | Measurement category |
| Unit Type | Category unit |
Step 5. Deploy Flow to apply Changes
