4.2 Recommended wiring
4.2.1 Bus/Communication architecture
RS232
One of following possibilities is available:
PC software interface (DriveConfig, InteliMonitor).
Modbus protocol option for SCADA systems.
Analog or GSM Modem interface.
IB-NT – internet interface.
CAN1 / J1939 / KWP2000
CAN1 is data line for controller Inputs/Outputs extension. It is possible to connect following extension modules:
ECU (Engine Control Unit),
IGS-PTM (8 BI, 8BO, 4AI, 1AO),
IS-AIN8 (8AI),
IS-AIN8TC (8AI – TC only),
IS-BIN 16/8 (16BI, 8BO),
Inteli IO8/8 (8 or 16 BI, 8 or 0 BO, 2AO).
Full physical CAN interface on ID-DCU Industrial is available, no ID-COM interface needed. Maximal CAN bus
length is up to 200m
CAN2
Inter-controller CAN for multiple engines applications. ID-COM module is necessary. It is possible to connect
ID-DCU Industrial controllers and/or
IG-MU (Direct cable, analog modem or GSM modem interface) and/or
IB-NT (Internet interface) and/or
The data rate is selectable in two levels: 250 kBd for 200 meters line and 50 kBd for 900 meters line.
Redundancy line (e.g.J1708)
There are 2 data lines in the system, one CAN SAE J1939 datalink and one SAE J1708/J1587 datalink. The
J1939 datalink is used for control and monitoring data. The J1708/J1587 datalink is used for redundancy control
and monitoring mainly in Volvo Penta systems.
The specific ID-COM interface is necessary to use for synchronous J1708/1587 data line.
CAN bus Connection rules
CAN bus line must be connected in series, from one unit to the next (no star, no cable stubs, no branches) both
ends must by the 120 Ω (internal or external) resistor terminated.
Maximal CAN2 bus length is up to 200 meters when Basic settings: CAN bus mode = 250 kBd or up to 900
meters when Basic settings: CAN bus mode = 50 kBd.
For CAN data cables details see chapter Technical data – Communication interface. CAN cable shielding
connect to ID-DCU Industrial case.
