Rockwell Automation 1769-SM2 Compact I/O DSI/Modbus Communication Module - Manual (Page 41)

Configuring the Module 3-3
The 1769-SM2 module has two methods of configuration, which are
determined by the Configuration Mode Switch (SW1 in
Figure 2.1 ):
•
Controller mode—The 1769-SM2 uses the configuration data
downloaded from the controller on power-up and when the controller
is placed in run mode. The data is configured using RSLogix 500,
RSLogix 5000 or RSNetWorx for DeviceNet.
•
Parameter mode—The 1769-SM2 uses its internal parameter settings
to configure the module. The data is configured using an optional,
external PowerFlex 4-Class HIM, DriveExplorer, or DriveExecutive.
Only one method can be selected, and it is used for all three channels.
When the Configuration Mode Switch (SW1 in Figure 2.1 ) is in the
default CONT (Controller) position, the 1769-SM2 uses the configuration
data downloaded from the controller on power-up and when the controller
is placed in run mode. Depending on the controller, configuration data is
allocated and entered using RSLogix500 or RSLogix 5000.
Configuration Data
The 1769-SM2 module contains a set of 42 words of configuration data
that is used to configure the module's behavior (
Table 3.C ). A software
tool, such as RSLogix 500, RSLogix 5000 or RSNetWorx for DeviceNet
is used to read/write the configuration data.
