Modbus frames for reading
This function is used to compile up to 32 Modbus frames for reading process values from external de-
vices (via interface) individually for each opposite end. The process values (analog and digital values;
texts) are written to the selected variables (external inputs and texts) from the received Modbus telegram
and are available for use in the paperless recorder.
Each frame can be used to configure up to 24 frame entries with a process value each, which are then
grouped and transmitted in a Modbus telegram.

CAUTION!
A variable can be used in multiple frames.
This means that different process values are written to the same variable.
The user has to make sure that a variable is not overwritten unintentionally.
Configuration and use of the Modbus frames for reading are described in the interface description.
