This input register request will read the current Peak value of
Analog Output 1, and will reset the value all in one action.
A.3.3 Channel States
The Channel States section contains the state of all the channels
in the EZ-ARRAY. Each register represents 16 channels.

Table A–39. Channel States Bit-Mask
Value State Description
0 Made The channel is made (clear)
1 Blocked The channel is blocked
For example, if the first and third beams of the EZ-ARRAY are
blocked, input register 30003 would contain the value 0x0005.

To read ALL Channel States, a read input registers request is
sent starting at address 30003, and requesting 23 registers.
The channel states can be accessed after each scan, if Cache
Mode is set to Extended in the Communications Configuration.
