4.26.4.9.5 Communication registers
4.26.4.9.5.1 Uploading the current curves (function models 0 and 1)
A current curve with 200 values is recorded for each channel. The interval between measurement points is equal
to a quarter of the defined X2X Link cycle.
The following registers are used to read the current curve recorded by the module:
•
•
Set the channel number and line index
Name:
AnalogInput01
If this register contains a valid value (i.e. index is in the valid range) then registers AnalogInput02 to AnalogInput09
provide a block of 8 current values for Channel X.
Data type
Value
USINT

Examples
The 200th value of the curve contains the switching point of the connected valve/relay found by the module.
•
Value 200 = 78: The 78th measurement point corresponds to the switching point of the valve/relay.
•
Value 200 = 255: No switching point was found.
Analog input values
Name:
AnalogInput02 to AnalogInput09
A current curve with 200 values is recorded for each channel. These registers provide a block of 8 current values
from Channel X.
The following register is required for configuration:
•
The AnalogInput01 register defines the channel used and the block index.
•
The interval between measurement points is equal to a quarter of the defined X2X Link cycle.
