13.9 Modbus frames for reading
This function is used to compile up to eight Modbus frames for reading process values of ex-
ternal devices (via interface) individually for each opposite end. The process values (analog,
integer, and digital values, and text) are written to the selected variables from the received Mod-
bus telegram and are available for use in the system. Each frame can be used to configure up
to 64 entries (variables); the process values are then grouped and transmitted in a Modbus
telegram.
Setup dialog box
NOTE!
The configuration and use of the Modbus frames for writing are described in the Modbus in-
terface description B 703571.2.0.
