Note:
Temperature: In order to see the temperature directly in the memory address, a conversion must be
made, since the data size is DINT and monitoring is done in 4 bytes. Therefore, it’s recommended to
use the associated symbolic variable, because it already provides the final temperature value.

wBreakErrorCounter
These counters are restarted in
the following conditions:
- Energizing
- Configuration of the COM 1
serial port
- Removal of RX and TX queues
PS.: When the CPU is set with
parity Without Parity, the counter
of errors of parity is not
incremented in case it receives a
different parity. In this case, it will
be indicated an error of frame.
The maximum value of each
counter is 65535.

Note:
Parity Error Counter: When the serial COM 1 is configured Without Parity, this error counter
won’t be incremented when it receives a message with a diferent parity. In this case, a frame error
will be indicated.
