AZ Modbus Driver
The A.Z. Modbus Driver is at the core of many of A.Z. System's projects. Here is a schematic representation of the driver.
The A.Z. Modbus Driver natively supports the following devices:
Brainchild16DO (16 channel digital output module)
Brainchild 8AI (12 bit 8 channel analog mA input module)
Brainchild 8AO (12 bit 8 channel analog mA output module)
Sierra Instruments Compod (SmartTrak2 massflow controller Modbus Add-on)
Sierra Instruments 640 (insertion flow meter)
Vogtlin ECO RedY massflow controller
Temco T3-8I13O (10 bit 8 channel analog voltage input, 13 relay output)
Analog to Modbus Controller
This project converts analog signals to digital Modbus RTU signals and visa versa.
The controller can control up to eight channels.
Also the Modbus RTU digital Mass Flow Controllers are hot swappable, using the automatic modbus configurator.
Implementing the AZ Modbus Driver on this project delivers dynamic baudrate Modbus RTU connection on one network.
Continuous Topup Manager
The Continuous Topup Manager is in purpose equal to the Smartfill MFU, but it differs on some points:
| Continuous operation |
| Standalone and unattended |
| GPRS/3G used for emailing reports |
| Native .NET firmware |
| IP65 Rated |
The system uses a Mass Flow Controller to ensure gentle top-up.
Two pressure transducers are used to monitor actual pressure and ensure hoses are leaktight.
Internal communicator is achieved by Modbus RTU RS485 2 Wire.
The HMI Software is based on Arwin Zonneveld's custom Modbus Driver.
