Software_Design_Notes_-_MultiChannel_Set64rs

Scanning Channel Installation Tool

• Assume a known fully installed serial port

DataBase Design

Fields = Channel# | NickName | Installed | Controller Type

• Channel Number will be both software channel identifier and modbus address > forcing user to sync software channel & modbus address
• NickName name of channel such as "glass melting kiln"
• Installed is retained even in event of link failure
• Controller Type > for future when various controllers can be managed

Installation - Address Setup

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

• prompt user to install in order they want to number the channels > modbus #1 goes 1st!
• connect controllers 1 at a time.
  • detect controller address
  • set controller address to next open channel
  • detect controller address again to verify successful setting of address
• put controller in to data base

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
