Generalcongurationofthehost

The data exchange with status and variables between eld device and host is carried out via

(4 bytes) according to IEEE 754 are transmitted with individually selectable order of the data bytes

(byte transmission order). This "Byte transmission order" is determined in the parameter "Format

Code". Hence the RTU knows the registers of the VEGAFLEX 83 which must be contacted for the

variables and status information.
