In the following there are the measuring ranges with corresponding function number
listed, which were supported by the analog module. With FFh the corresponding channel
is deactivated. The formulas listed here allow you to transform an evaluated measuring
value (digital value) to a value assigned to the measuring range (analog value) and vice
versa.

Diagnostic data
So this module does not support diagnostic interrupt functions, the diagnostics data serve
for information about this module. On error the corresponding channel LED of the module
is activated and the error is registered in the diagnostics data.
The following errors are listed in the diagnostics data:
n
Error in project engineering / parameterization
n
Measuring range overflow
n
Measuring range underflow
DS - Record set for access via CPU, PROFIBUS and PROFINET. The access happens
by DS 01h. Additionally the first 4 bytes may be accessed by DS 00h.
IX - Index for access via CANopen. The access happens by IX 2F01h. Additionally the
first 4 bytes may be accessed by IX 2F00h.
SX - Subindex for access via EtherCAT with Index 5005h.
More can be found in the according manual of your bus coupler.
