¶ General
The program is designed to receive data from the axle load sensor AXISLOAD from PROFITECHCIFRA LLC.

¶ Implementation
¶ General Logic
The program listens to the RS-485 interface and parses data from the axle load sensor.
¶ Main Parameters:
-
Total Load
This is the total load on all axles (taken "as is" from the sensor) -
"Overload"/"Normal" Status
Global overload flag (taken "as is" from the sensor) -
Data Validity Flag
A flag that allows validating data on the monitoring server
¶ Additional Parameters:
Since the AXISLOAD system can work with a variable number of axles, for the universality of the implementation, the program does not save data on the load for each axle. Instead, a parameter "Maximum load value on one of the axles" is formed.
-
Number of Axles
-
Maximum Load Value on One of the Axles
When receiving data for the axles, the program compares all loads and saves the maximum value in this parameter -
"Raised"/"Lowered" Statuses for Each Axle
A flag field containing the operating modes of all axles -
"Overload"/"Normal" Statuses for Each Axle
A flag field containing the overload statuses of all axles
¶ Configuration
¶ In the Device Configuration
¶ On the "RS-232/RS-485" Tab
On the RS-485 interface, select:
| Setting | Value |
|---|---|
| Device 1 | Complex Events (asynchronous) |
| Baud Rate | 57600 |
| Parity | None |
| Stop Bits | 1 |
¶ On the "Complex Events" Tab
- Enable the Complex Events function. And write the configuration to the device (then reconnect to the device and continue)
- Load the program into the device.
An example of loading a program into a device is described in this article
- Configure User Parameters
- To complete the configuration, write the configuration to the device again.
