4.9 Modbus TCP

Note. Modbus TCP is available only if the optional ethernet module is fitted.
Modbus TCP enables Modbus devices to communicate via an ethernet network transferring Modbus messages via TCP/IP.
Communication with standard, serially connected, Modbus RTU devices is also possible through a Modbus TCP Gateway.
Refer to the Ethernet Communications Option User Guide Supplement (IM/SMENET) for information on how to install, configure and
use the instrument on an Ethernet network and for information on configuring and using the Modbus TCP facility.
Refer to Appendix B, page 106 for further information on using the Modbus link.

Select the analog output source.
Note. The analog output source can be any internal or external
analog signal.
Set the required analog output engineering and electrical
ranges.
Note. The 'Engineering low' and 'Engineering high' settings are
the engineering values corresponding to the 'Electrical low' and
'Electrical high' values below.
The 'Electrical low' and 'Electrical high' values are the minimum
and maximum values of the current output, in Electrical units –
range 0 to 23mA.
