The MIQ/TC 2020 XT, configured as a terminal/controller, provides 4
steps of system security:
Note
Information on access to the system is given in section 4.3.
Delivery condition Access control is switched off in the delivery condition.
Every user can carry out all functions.
Saving the password If access control is enabled for the IQ S ENSOR N ET and the
administrator password is lost, quick administrator access to the
IQ S
ENSOR N ET is not possible.
To avoid the loss of the password we recommend to create a back-up
of the administrator password. This also applies to the use of the
electronic key.
To be on the safe side, you can store the administrator password on an
electronic key and/or note it on paper or a PC. Store the passwords in
a safe place.
