Configuring GCP-30 and LS 4 Modbus access

Access from the Modbus to a GCP-30 and LS 4 unit can be configured on a per unit basis.
You have the option of completely disabling a gen set control for Modbus access, have
read-only access or enabling remote control either unsupervised or time-out supervised.
To configure the Modbus access, enter the Configuration sub-menu and click on
either the GCP-30 or LS 4 menu entry. This opens either the GCP-30 settings or the LS
4 settings as shown below:

The CAN identifiers and Modbus slave identifiers are preassigned and cannot be changed.
The following Modbus access options can be selected:
disabled
Modbus access to this unit is completely disabled. The gateway does not respond
to a Modbus master query and ignores messages for the associated Modbus slave
ID. The associated slave ID can be used by another Modbus device connected to the
Modbus network.
read-only
Modbus access is enabled for read-only data. No remote control is possible, access to
the remote control data table 4:0001 will result in Modbus exception code 03 Illegal
Value being returned.
control
Modbus access is enabled for reading and for remote control. No supervision of
Modbus master activity takes place (See Monitored Control). Before being able to
use Remote Control, please check that the GCP-30 unit has been parameterized
accordingly, otherwise the messages sent by the GCP-MG are ignored by the GCP-30.
Refer to chapter Interface in your GCP-30 Series Genset Control manual. For Remote
