Software_Design_Notes_-_MultiChannel_Set64rs
Scanning Channel Installation Tool
- Assume a known fully installed serial port > user uses serial port scan tool first
DataBase Design
Fields = SoftwareChannel | ModBusAddress | NickName | Controller Type
- SoftwareChannel will be both software channel identifier and modbus address > forcing user to sync software channel & modbus address
- ModBusAddress unit addresses
- NickName name of channel such as "glass melting kiln"
- ControllerType Example: set64rs > for future use to allow mixed controller usage
Installation - Address Setup
Notes System may need to preserve certain ModBus addresses for other than this software - thus:
- a channel to modbus map is needed
- some addresses may be skipped
Steps
- prompt user to: Set each controller to a unique address > can use the address change utility
- scan the port: User has 2 options
- add each controller seen to the ChannelMap
- delete any ChannelMap address entries in the table that do show up as not having an controller connected
Initialization Scan
- Do initial scan to see which controller addresses are installed
- Stores status in the database table under INSTALLED?
Manual Method
- User looks at database and selects address
- User can manual set / select controller modbus address using controller front panel
Automated Method where computer helps
- Prompt User > connect unit to be installed > disconnect all other controller communication cables
- Scan address 1 - 64 until unit is found > look for valid reply
- Check to see if this address is already used:
- Prompt User > This address is already in system use by NICKNAME | This address is not already in use
- Prompt User > You can Change address by clicking X Button. ( has textbox display and button pair + number only parsing ) > verify not already in use!
- If user changes address > rescan to verify change in effect > Prompt User > change effected
- Prompt User> Store this in channel database? Click Store Channel
