PLCBUS OBJECT
- This is a generic replaceable object
- This object needs the following methods:
Methods
Initialize()
- What it does:
- any Object initialization you may need.
- When is this called:
- Upon Object creation.
- What you will get:
- nothing.
- What you will return:
- nothing.
dceCommandIn(cmd)
- What is does:
- sends you a command object to allow you to create gsdOut().
- What you will get:
- cmd (Command Object)
- What you need to return:
- nothing (ignored)
- When you will get this:
- executed when a new DCE command is sent to you.
dceResponseIn(cmd)
- What it does:
- Sends you a DCE object to compare with the command.
- What you will get:
- cmd (Command Object)
- What you need to return:
- TRUE if you accept this response.
- FALSE if you do NOT accept this response.
- When you will get this:
- executed when a new DCE response is ready.
gsdCommandIn(value)
- What it does:
sends you a String to allow you to create a dceOut().
- What you will get:
value (String Object)
- What you need to return:
nothing (ignored)
- When you will get this:
executed when a new GSD command is sent to you.
gsdResponseIn(value)
What it does:
Sends you a GSD Response to compare with the command.
What you will get:
cmd (Command Object)
What you need to return:
TRUE if you accept this response.
FALSE if you do NOT accept this response.
When you will get this:
executed when a new GSD response is ready.
dceout()
- What it does:
Creates a Command Object to send to DCE.
- What you will get:
nothing.
- What you need to return:
a Command Object representing the previous gsdCommandIn.
- When is this called:
After a gsdCommandIn has been sent.
gsdout()
- What it does:
creates a String Object to send to GSD.
- What you will get:
nothing.
- What you will return:
a String Object representing the previous dceCommandIn.
- When is this called:
After a dceCommandIn has been sent.
Properties:
@responseAccepted
What it does:
signals that the current response is accepted as valid.
When you should set this:
@responseNeeded
What it does:
signals when you need a response.
@commandHolder
What it does:
If you need to create a new command, this is the holder for it.
