8
Analogue load sharing
(future use)
9
DEIF network
The DEIF equipment communicates with other
DEIF equipment using this network.
Send inputs from the display unit to the
controller, and information from the
controller to the display unit. Send
information from one controller to another,
including power management, load sharing,
and heavy consumers.
10
Modbus TCP/IP
Allows external devices to communicate with the
controller using the Modbus TCP/IP
communication protocol.
A wide variety of purposes, including
monitoring, off site control, and alarm
handling.
11
Internal communication
Allows DEIF controllers to communicate with
DEIF extension units. The communication ports
are located on the power supply modules (PSM).
Extend controller functionality by adding
additional inputs and outputs to one or more
extension units.
2.2.4 Maximum number of controllers
The DEIF power management system allows a total of up to 32 controllers per DEIF network ring. That is, you can assign up to 32
Controller ID
numbers.
These restrictions also apply:

GENSET controller

2.2.5 Restrictions
PPM 300 is not suitable for all possible marine configurations. Some configurations, which require an engineered controller solution,
like DEIF's Delomatic, are listed briefly below.
Shaft generators cannot run in parallel with each other
PPM 300 allows multiple SHAFT generator controllers. If the shaft generators must connect at the same time, then they
must
be on
separate busbar sections. However, during power take home, one shaft generator
can
drive another shaft generator.
Shaft generator cannot run in parallel with a shore connection
The
shaft generator and shore connection cannot run in parallel
with each other. If they run at the same time, they must
connect to separate busbar sections.
Redundant busbar is not supported
PPM 300 controllers
cannot control a system with a redundant busbar
. If you need to control a system with a redundant busbar,
use the DEIF Delomatic controller.
