Applications

EDS500 devices can transport serial data streams via the Ethernet/IP network (asynchronous
EIA-232 and EIA-485 protocols and applications). This means that modern internet technology
can be used simultaneously with established legacy technology. Possible applications
include RTU communication (Remote Terminal Units), AMR (Automated Meter Reading), SPS
applications a.m.m.
The communication technology can be updated in a migration scenario without the need to
replace the hardware or configuration of the remote terminal units if a serial tunnel is used.
Furthermore, the replacement does not have to happen in one step but can be carried out
step by step (e.g. to replace FSK based modem lines).
