WAGO I/O System 750 Series Manual page 53

Example for static assembly (default assembly):
The default assembly is:
In this example, the fieldbus node arrangement looks like this:
1) 1 ECO fieldbus coupler DeviceNet (750-346),
2) 1 digital 4-channel input modules (i. e. 750-402),
3) 1 digital 4- channel output module (i. e. 750-504),
4) 1 analog 2- channel output module with 2 bytes per channel
5) 1 analog 2- channel input module with 2 bytes per channel
6) 1 End module (750-600).
