E-58 Application Examples
Please refer to the Hardware Setup section at the beginning of
this application example to match the slot numbers in the M-file
addresses to the slot numbers of the scanners in their respective
chassis.
When you are finished configuring the connection in the
Connection Properties screen:
6. Click APPLY.
7. Click OK.
You must also enter a value in the Status Address field. This field
supplies Connection Status information to the processor. The
starting bit addresses for this field must be an even number,
because two consecutive bits are used as status for each
connection. The even numbered bit indicates whether the
connection is open or closed and the odd numbered bit
indicates whether the connection is in normal operation or Idle
mode. In this example, the address chosen for the first
connection is the first available bit pair, M1:3.600/00.
The next connection automatically created by RSNetWorx for
ControlNet software uses M1:3.600/02.
You must now save your Scanlist for node 1 to the network
keeper.
8. Click the Save icon or click the File menu and then Save.
You will be prompted to Optimize and re-write schedule for all
connections.
9. Click OK.
1 0. Click YES to the warning message.
To create a connection to have node 2 send 60 words of data to
node 1, enter the Scanlist for node 2 and create a Send Data To
connection under node 1. RSNetworx for ControlNet software
will then automatically create a Receive Data connection under
node 1 in the node 1 scanner’s Scanlist. The SLC processor in
the same chassis with the node 2 scanner will then need to copy
60 words of data to M0:1.3. The SLC processor in the same
chassis with the node 1 scanner will then need to copy 60 words
of data from M1:3.3.
