Very High-Speed Counter Module Input and Output Data 3-3
Finally, in rate measurement [7] configuration, it is the total number of
pulses seen at the A input accumulated over each period as specified
by the product of the time base x gate interval. The range of values
occupy the entire 32-bit size from 0
≤ value ≤ 0xFFFFFFFF
(4,294,967,295). Changing the configuration does not clear these
words.
Module/Channel Status and Programming Error Codes (Input
Words 3 and 4)
Programming Error bit (PE) - If an incomplete, incorrect, or
conflicting set of configuration parameters is sent to the module, the
PE bit is asserted and an error code is placed in the Programming
Error Code word (assembly 68
16
). The module will not enter a normal
operational state.
Bit definitions for the error code are:
E10:
An invalid assembly was chosen for poll consumption (0, 105,
or 106 are valid).
E9:
The decimal point position is outside of acceptable range.
E8:
Counter 0 window ON and OFF values are equal and not zero
OR Counter 0 window ON or OFF value greater than
0x00FFFFFF.
E7:
A tie has been connected to an unprogrammed window.
E6:
A configuration was selected that requires the scalar and none
was programmed or Multiple scalars were selected.
E5:
The preset is out of range ( > 0x00FFFFFF).
E4:
A rollover of zero was programmed though PWM was not
selected OR A rollover was programmed and PWM was
selected OR Rollover is out of range ( > 0x01000000).
E3:
A configuration requiring time base was selected and no gate
interval was set OR Gate interval is out of range ( > 200) OR
Product of time base and gate interval is greater than 3
seconds.
E2:
A time base was entered that is not a multiple of 10 OR Time
base is out of range ( > 3000 or 3 seconds).
E1:
ZF/BF/AF were selected and no filter was programmed OR
Multiple filters were selected.
E0:
A reserved configuration/mode was programmed.
