Controller Timing
The Universal Controller needs a master clock for operation which is either generated
internally or via the synchronization pulse. Each timing pulse initiates a process of data
recording and calculation.
All calculation blocks are passed through during the calculation. With the next pulse, the
calculated values are output and a new calculation is started simultaneously.

Analog output
: The output is performed at the analog output and is available there im-
mediately.
Digital outputs
: The digital outputs (limit values), depending on the settings, can also
react with a delay and delay and hold the output over several cycles.
RS422
: The output of a value at the RS422 serial interface starts approx. 50 µs after the
period edge.
In the case of a low baud rate or a short master clock, individual values can be skipped
during the output.
Averages may need several values until the averaging depth is reached; however, de-
spite this, the output of the values starts immediately with the following period.
If the master clock period has been selected too short, the duration of the processing
cycles is extended in each case by one master clock.

Ethernet
5.7.1 Basic Settings for the Data Output
The controller can continuously send its calculated measured values using UDP/IP or
TCP/IP to a measured value server.
The settings for the measured value server can be made in the menu Ethernet connec-
tion > Ethernet measurement transmission.

Server TCP|IP
Client TCP | IP
Client UDP | IP

Value
The data transfer uses "Little Endian" as the data format. Here, the byte with the lowest
value bits (least significant bits) is saved first, i.e. at the smallest memory address.
