5-4 Start-Up, Operation, and Troubleshooting
The parameter that caused the error is indicated in the Configuration
Error Code field (I:e.4/0-7). The table below lists the configuration
error code and indicates the required action to clear the error.
Application Errors
The module can encounter the following application errors.
Linear Counter Overflow/Underflow
When the maximum count is exceeded, the Over/Underflow bit
(I:e.0/13) is set to 1. Clearing this error requires reconfiguration. The
module controlled outputs are reset to 0 while this error is present.
Outputs controlled by the user program are not affected.
Rate Counter Overflow
When the Rate Counter exceeds 32,767, the Rate Counter Overflow bit
(I:e.0/4) is set to 1. The module will continue to run the rate
measurement and will clear this error if the input frequency drops
enough to avoid the counter overflow.
This error can also be cleared by the user program reducing the Rate
Period parameter. If operating in the Rate Mode, the module
controlled outputs are reset to 0 while this error is present. Outputs
controlled from the user program are not affected.
