RSNetWorx for DeviceNet allows you to identify the network and configure
the I/O modules with easy-to-use Electronic Data Sheets (EDS). Point to the
field and click your selection.
To download EDS files for use in configuration, go to rok.auto/pcdc.
EDS files for blocks with matching catalog numbers (for D-shell and
removable terminal block versions) are the same. The website, or in
RSNetWorx for DeviceNet, there may be only one catalog number that is listed
for both versions.
When using third-party configuration software, load the EDS files into the
software and follow the vendor's instructions.
To configure analog modules, follow these steps:
1. Open RSNetWorx for DeviceNet.
2. Add an analog input module (for example, 1790D-N4C0) to the network,
as shown in Figure
