Connecting and disconnecting an HT 6 during running operation
To be able to connect an HT 6 to or disconnect from an automation system with-
out any trouble during operation, make the following arrangements:
S
The EMERGENCY STOP of the HT 6 must be enabled or jumpered,
S
The HT 6 must be connected to the MPI bus through a PROFIBUS repeater.
For a detailed description of the actions to be taken and the devices required,
please refer to:
