## Controllino - Mega
|
|
|
|
- [Unit Testing](https://docs.platformio.org/en/latest/plus/unit-testing.html?utm_medium=piohome&utm_source=platformio)
|
|
- Semiphores : emulated, via ASM noops
|
|
- Memory: seems stable with modbus over ethernet
|
|
|
|
### Omron MX2
|
|
|
|
- [Programmer](./firmware/OmronMx2.cpp#L460)
|
|
|
|
### Omron - E5DC
|
|
|
|
### Calibration
|
|
|
|
- [TC calibration](https://www.tcdirect.co.uk/product_2_133_21#133/21/1)
|
|
|
|
# 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
|
|
- [x] 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](./firmware/components) for more)
|
|
- [ ] ramp times, window keeping
|
|
- [ ] test PVC/PFA [TC cables](https://www.tcdirect.co.uk/product_2_270_1)
|
|
|

|
## 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
|
