0x68 count 0x68 count Value
Thereby, the first value is sent with Count = 1. For flow control, count is reflected by KS800 (? once). The
values are transmitted in the order real - integer.

3.6 Examples
3.6.1
Function block protocol principles
A function block has input and output data (process data) as well as parameter and configuration data. It is
addressable via a function block number.
The following access mechanisms are used:
3.6.2 Individual access
This access (code xx) can be used for reading or writing an individual value of a function.
Valid values for ID1:
Configuration as
FixPoint:
0 = integer real values are transmitted as integer (without digits behind the decimal point)
1 = real real values are transmitted as FixPoint (1 digit behind the decimal point)
Example 1: (message structure with data sending)
Transmission of parameter set number (ParNr = 1) to the controller (channel 2).
