Figure 10.5-3 Selection of Modbus on the Commination setting menu
Note; This sample menu illustrates how to select the Modbus, so that we discuss neither
the inclusion of IEC61850, IEC103, and DNP3.0, nor the selection of those
protocols. See Figure 10.1-1 to check the inclusion of the protocols in the IED.
The Modbus slave operation can be switched off briefly if the setting [MODBUS_BLK] = On.

10.5.3
When the Modbus protocol is provided in the IED†, the measurement and status information
of the IED are transferred to the substation computer by that protocol. It is executed with
message frames from the substation computer message (called "Master query"); then, the data
(called "Slave response") is transferred to the substation computer from the IED. The message
frames can include the following data:
Measurement:

Event status:

Time:

†Note: The GR200-series IEDs do not support to applications (control functions, such as,
DPOS etc.) in the Modbus protocol.
