Fieldbus Coupler 750-346
WAGO-I/O-SYSTEM 750
DeviceNet
Example for static assembly (default assembly):
The default assembly is:
Output1
(I/O Assembly Instance 1)
Input1
(I/O Assembly Instance 4)
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
(i. e. 750-552),
5) 1 analog 2- channel input module with 2 bytes per channel
(i. e. 750-456),
6) 1 End module (750-600).

CS = Coupler Status (The last byte in the input process image is the Status Byte
of the Coupler, CS01...CS08, see also Object 0x64, Instance 1, Attribute 5)
CS01 =1: internal bus error (0x01)
CS02 =1: module communication error (0x02)
