Customer-specific linearization
You can use the customer-specific linearization to create a customized linearization characteristic line
for analog values. Two procedures are available for this: formulas or grid values (value pairs).
Temperature values must always be specified in °C. In general, use the measuring units without prefixes
(e.g. A instead of mA).
Formula
Customer-specific linearization is specified using a polynomial. The polynomial is calculated for the en-
tire linearization range.
Example (4th order polynomial): y = X4*x

Description
Up to three time servers can be entered.
The server list is processed top down, in other
words, the next time server on the list is only que-
ried if the previous server is unreachable.
It must be ensured that the server name is re-
solved to an IP address via a DNS server (see
Configuration > Ethernet).
Maximum time in seconds between the client's re-
quest and the server's response (for local time
server).
Description
Device's time settings (NTP must be inactive)
In the web application, the PC's time settings are
applied (the current time in the device is not
shown). These settings can be changed individual-
ly.
