Creating Connections to Analog I/O Modules
Note: You must always create a connection to the discrete I/O in the
chassis, even if you are interested only in the analog modules in the
chassis.
1. Right click on the analog module and select Insert Connection.
2. Set the Connection Name to Discrete Exclusive Owner.
3. Set the Requested Packet Interval to the desired update rate. The RPI
must be greater than or equal to the network update time (NUT).
4. Set the Input, Output and Configuration sizes to the desired values.
Refer to the documentation for the module for details. Most modules
can be configured in more than one way – the values you choose
here depend on the type of module and how you want to configure it.
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. If the module has a Configuration Setting tab, select it and enter
appropriate values for the configuration data. Refer to the module
documentation for details.
7. Click OK to complete the configuration.
Configuring Flex I/O
You create a single connection for all the discrete modules in a Flex rack,
and individual connections to the analog modules.
You do not have to create a connection to the discrete modules to create
a connection to an analog module.
When you put RSNetWorx online, it should find and display the modules
in the Flex rack.
Discrete Connection
To create the connection to the discrete I/O in the MBCN Scanlist
Configuration:
1. Right click on the Flex ControlNet adapter and select Insert
Connection. The Connection Properties dialog opens.
2. Set the Connection Name to Exclusive owner.
3. Set the Requested Packet Interval to the desired update rate. The RPI
must be greater than or equal to the network update time (NUT).
This time will be the update time for all the discrete modules in the
rack.
4. RSNetWorx automatically sets the Input and Output sizes to the
maximum values. You can reduce these sizes if the higher slots are
