3.8 KiB
3.8 KiB
Controllino - Mega
- Unit Testing
- Semiphores : emulated, via ASM noops
- Memory: seems stable with modbus over ethernet
Omron MX2
Omron - E5DC
Calibration
Extrusion Firmware
Communication modes
- [-] Custom Serial over RS485 (Extruza, 3dtreehouse)
- [- Standard Serial (Lydia-v4.5 - touchscreen/RPI)
- [- Pure RS485 - Slave|Master (In conjunction with injection addon)
- [-] Bluetooth
- [-] App template
- TCP
- Modbus (rev 1, base abstract/odel)
- ProfiBus (rev 2)
- DeviceNet (rev 1)
- Debug Serial (Always)
Protocol
- Internal: add duplex for RS485 feedback
- [-] Add command queue lifecycle / state response
- [-] Handshake
- [- Checksum
- Broadcast (for bluetooth as well)
- [-] User space / reserved
Controls
- Simple cycle control via logic/analog interface
- Controllino - Mini/Uno version (http://www.kuehlschrankdichtung.de/ | PVC temp and cycle time profile storage)
Modbus testing strategy for vendors
- 1. test basics after unboxing
- 2. programmer test
- 3. stress/flood test
- 4. EMI near (scope)
- 5. EMI long / cable test (serial debugging with scope)
PID / TC related
- [-] determine barrel empty / full ratio/constant impact on PID readings
- [-] determine actual PID values, independent via calibration devices (see ./firmware/components for more)
- ramp times, window keeping
- test PVC/PFA TC cables
Components
- Add HMI column
- Add register range
- Add wire labels

Modbus design notes
- each issued read/write has a corrosponding state flag register, eg: issued, proccessing, processed, error code, failure
- use coils only
- when in duplex, feedback channel provides command queue id with state flag, polling should be avoided
- avoid multi bytes/long/strings
- each category shall provide additional user register space
