Q: Can I set up the DS54 to act as an emergnecy stop device?
A: Any unused DS54 input can be configured to send an Emergency (OPC_IDLE) Stop packet.
The typical Emergency Stop circuit is a supervised series of one, or more, normally closed switches or contacts.
When any one of these devices is opened the circuit is deactivated and everything affected by the Emergency Stop circuit immediately shuts down.
The following drawing depicts a typical Emergency Stop circuit using a DS54.
