2.3 Connecting signals

2.3.1 Naming

In multiple board systems a clear defined channel name structure is important to avoid inconstancy in the

channel connection. Usually analog input channels are just named in a row. Therefore at a 3 board system

the channels are named from CH 0 to CH 23. Due to the flexible structure of the digital and counter inputs

the naming in a row is not possible. That’s why each input at the ORION base board (code letter B) and also

at the expansion board (code letter E) gets a channel prefix name like shown in the example below for a two

board system.
Following block diagram explains the naming:

Multi board system

ORION-Base-board 0

Source B0_CNT0, Gate B0_CNT0, Aux B0_CNT0

Source B0_CNT1, Gate B0_CNT1, Aux B0_CNT1

B0_DI0 to B0_DI15

ORION-Expansion-board 0

ORION-Expansion-board 1

Source E1_CNT0, Gate E1_CNT0, Aux E1_CNT0

Source E1_CNT1, Gate E1_CNT1, Aux E1_CNT1

E1_DI0 to E1_DI31

Source B0_CNT0:

Is the source input of CNT0 on ORION-Base-board 0

E1_DI5:

Is the fifth digital input on ORION-Expansion-board 1
