0 = Indicates that optical module 3 thru 0, respectively, have not

 

 

 

 

detected a communications error. This is the normal quiescent

 

 

 

 

state.

 

 

 

 

1 = Indicates that the optical module indicated has detected a

 

 

 

 

communications error, and may or may not have processed the last

 

D7-D4

Optical Module

 

command sent to it. May be used to identify a module that has

 

 

become unresponsive.

 

Access Fail Bits

 

 

 

 

Pon state = 0

 

 

 

 

 

 

 

 

A read of this bit location will indicate whether the optical module

 

 

 

 

indicated has detected a communications error. These bits are

 

 

 

 

normally not used by the operator. Their usefulness is only in

 

 

 

 

trouble shooting possible module problems.

 

 

 

 

0 = Indicates that optical module 3 thru 0, respectively, are

 

 

 

 

operating normally. This is the normal quiescent state.

 

 

 

 

1 = Indicates that the optical module has set its Error Output to

 

 

Optical Module

 

indicate an error condition. This signal is used to identify a module

 

D3-D0

 

that is operating in error.

 

Error Bits

 

Pon state = 0

 

 

 

 

 

 

 

Possible reasons for this bit being set by the optical module in

 

 

 

 

question are:

 

 

 

 

1) Requested channel on a multi switch module is out of range,

 

 

 

 

user error.

 

 

 

 

2) Stepper motor error has occurred, device malfunction.

 

 

 

 

3) Proximity sensor switch error has occurred, device

 

 

 

 

malfunction.

 

 

 

 

4) Requested attenuation is out of range, user error.

 

 

 

 

The module Error Bits should be polled by the user to determine

 

 

 

 

proper module operation.
