5.4 Protection against manipulation
5.4.1 Introduction
The PAC2200 is equipped with a range of mechanisms to protect against deliberate and
inadvertent device manipulation.
● Password protection
● Hardware write protection
● IP filter
● Configurable Modbus TCP port
The closed padlock symbol in the display title indicates whether "password protection" or
"hardware write protection" is activated.
The device is protected against write access.
The device is not protected against write access.
5.4.2 Password protection
Password protection prevents write access via the device interface and the
communication interfaces, in particular:
● Changing of device settings, including password.
● Changing and deletion of values/parameters.
● Deletion of data and memory content.
● Setting and resetting of counts.
● Resetting to factory settings.
Reading out of measured values and memory content is still possible when password
protection is active.
As soon as the password has been entered in the device once, it is not requested again as
long as the "SETTINGS" menu level remains active.
Password policy is a four-digit number from 0000 to 9999. (Default password: 0000)
