5. RSNetWorx assigns the Input Address, Output Address and Status
Address automatically if Enable automatic addressing on insert is
turned on. If you want to manually assign these addresses, enter the
values.
6. Click OK to accept the connection.
Example:
To produce 120 words of data on the MCN and consume them on the
ControlLogix, create a produce connection of size 120 on the MBCN,
then create a consumeddata type in the ControlLogix that consists of a
DINT and an array of 120 INTs. Create a tag in the ControlLogix that
uses this data type.
Setting the Network Properties
From the main RSNetWorx window, select Network/Properties… Set
the Network Update Time (NUT) in ms, the Max. Scheduled Address
(SMAX), the Max. Unscheduled Address (UMAX), and the Media
Redundancy. If necessary, you can select the Media Configuration tab
and add any repeaters, etc. on your network.
Downloading the Configuration
When all the configuration information has been entered into
RSNetWorx, select Save to save and download the configuration. The
Save Configuration dialog box appears. Select Optimize and re-write
schedule for all connections and click OK. Answer Yes to break
connections and download.
Putting the MBCN in Run Mode
Before you put the MBCN in run mode, your program should check the
NAM (network attachment monitor) state to confirm that the MBCN is
online. Refer to page 60 for information on how to do this.
Put the MBCN in run mode by setting bit 1 in register 5.
The MBCN goes out of run mode when you do a stop all in the AutoMax
or when you clear bit 1 in register 5.
Accessing I/O Data
You assign the location for the data for each connection either manually
or automatically in the Scanlist Configuration tool. If you assign
locations manually, RSNetWorx checks that there are no overlaps.
