SGS uses a mapping
database to define which Modbus data points are to
be exchanged between the Modbus Transfer Tables
and the Harmony function block in the controller’s
configuration. Harmony function blocks typically
contain more information than an equivalent Mod
bus point can support, making it necessary to map
more than one Modbus point to a single Harmony
function block. SGS employs the use of multi-map
ping to allow quality, alarms and values to be fully
defined within the ModbusTCP configuration.
On the ModbusTCP network, connections between
client and server devices are made through TCP
sockets. Depending on the module being used, SGS
can be configured to a maximum of 8 server connec
tions to foreign Modbus clients and 128 client con
nections to foreign Modbus servers.
Features and benefits
• Bi-directional communication in real-time with
Modbus devices
• Support for standard Modbus function codes and
exception codes
• Exception and cyclic data writes
• Fully tunable communication rates
• Diagnostics enable isolation and troubleshooting
of one connection
• Support of online configuration (change in function
blocks of the SGS points) with redundant controllers
