Module Programming Errors
A programming error is caused by improper set up of a module
parameter. The module responds to a programming error by setting
the programming error bit. When this bit is set, the entire
programming block is rejected.
The programming error bit is set when a reserved bit is set. It is also
set under the following conditions:
Table 5.1 Error Conditions by Programming Block
Programming
Block Error Conditions
Module Setup • Operating mode bits are not set to a valid pattern.
• A counter’s range allocation value is greater than 16.
• The sum of all range allocation values is greater than 16.
• The range allocation value for Counter 2 and/or Counter 3 is
nonzero and the programmed operating mode has the counter
disabled.
• A counter or counters were running when the block was sent.
• The INT bit was set in Class 1.
• The RVF bit was set in Class 1.
Counter
Configuration • Counter number bits are not set to a valid number.
(Operating mode may be incorrect.)
• Input configuration is invalid for the counter.
(Operating mode may be incorrect.)
• G/P mode is invalid for the counter.
(Operating mode may be incorrect).
• The selected counter was running when the block was sent.
• The program counter number bits are not set for a counter that
has one or more bits set in its corresponding counter setup
word.
Min./Max.
Count Value • Counter number bits are not set to a valid number. (Operating
Mode may be incorrect.)
• The minimum count is outside its valid range.
• The maximum count is outside its valid range.
• The maximum count is less than or equal to Minimum Count.
• Programmed output count ranges are outside the bounds of the
new minimum/maximum count values.
• The preset value is outside its valid range.
• Counter was running when the minimum/maximum count
value was changed.
