WARNING

LOSS OF CONTROL

Due to the risk that a value entered on the terminal may not reach the equipment

(for example, if a communication break occurs due to huge bandwidth

consumption, the value may not be sent to the PLC) you are not allowed to use the

terminal to pilot safety critical processes, for example emergency stop or crane

load manipulation where human beings may get injured.

Failure to follow these instructions can result in death, serious injury, or

equipment damage.
