An Example

For example, if you have an island bus with eight I/O modules:

1 NIM

2 STB PDT 3100 24 VDC power distribution module

3 STB DDI 3230 24 VDC two-channel digital input module

4 STB DDO 3200 24 VDC two-channel digital output module

5 STB DDI 3420 24 VDC four-channel digital input module

6 STB DDO 3410 24 VDC four-channel digital output module

7 STB DDI 3610 24 VDC six-channel digital input module

8 STB DDO 3600 24 VDC six-channel digital output module

9 STB AVI 1270 +/-10 VDC two-channel analog input module

10 STB AVO 1250 +/-10 VDC two-channel analog output module

11 STB XMP 1100 island bus termination plate

The NIM would auto-address it as follows. Note that the PDM and the termination
plate do not consume island bus addresses:
