Caution!
Due to safety requirements regulated by international standards, implementing an
E-stop element via SDL (using Matrix) is NOT allowed. Instead, such an element
must be wired according to the safety requirements.
Information:
Display data will not be updated and cannot be read by the MTCX while a display unit
is in upgrade mode (e.g. SDL firmware upgrade).
The nominal time specifications are not guaranteed maximum lengths of time, but
may be increased due to e.g. transfer disturbances and external influences.
