This Application Note describes how to perform remote control operations like genset start, stop and
alarm reset using Modbus and the GCP-MG gateway.
Preparation
All devices have to be configured first to a allow remote control as it is disabled by default. The
GCP-30 unit also requires some hardwiring.
GCP-30 setup
Before being able to use remote control, please check that the GCP-30 unit has been parameterized
accordingly. Refer to chapter Interface in your GCP-30 Series Genset Control manual.
• GCP-30 parameter 120
• Discrete input
Automatic 2
• GCP-30 parameter 122
edgment is required.
• GCP-30 must be in
Automatic
GCP-MG setup
Remote control needs to be enabled on the GCP-MG gateway for each device.
Use a web browser and point it to the IP address of your GCP-MG gateway. The overview page will
appear.
To configure the Modbus access, enter the
or
menu entry. This opens either the GCP-30 settings or the LS 4 settings.
LS 4
For each device you require remote control, set to either
below. Save the configuration settings.

It is easier to test with the less monitored control complex non-monitored control mode first. Testing Use a Modbus simulator to test the remote control.
