12.4 Configuration
The configuration defines how many process data (byte and word) are exchanged during the
cyclic communication between control system and measuring amplifier.
Several modules enable a flexible use of the measuring amplifier. In a single measuring
amplifier only one module can be set active at the time.
Module 1: Basic telegram
4 bytes (2 word) are transmitted from the control system to the measuring amplifier and also 4
bytes (2 word) from the measuring amplifier to the control system in each data cycle.
Byte 0 Byte 1 Byte 2 Byte 3
