Note:
The fields Time-out t1 (s), Time-out t2 (s) and Time-out t3 (s) are dependents between themselves and must be configured
in a way that Time-out t1 (s) be bigger than Time-out t2 (s) and Time-out t3 (s) be bigger than Time-out t1 (s). If any of these
rules be not respected, error messages are going to be generated during the project compilation.
ATTENTION
For slow communication links (example: satellite communication), the parameters Time-out
t1 (s), Time-out t2 (s) and Time-out t3 (s) must be properly adjusted, such as doubling the
default values of these fields.
