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
4
+ X3*x
3
+ X2*x
2
+ X1*x + X0
Server 1
Server 2
Server 3
Enter the address of the time
server (or use an existing ad-
dress)
Example: de.pool.ntp.org
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 round-
trip time
0 bis 99999
(

)
Maximum time in seconds between the client's re-
quest and the server's response (for local time
server).
