Technical Information
PLUS+1 SC0XX-1XX Controller Family
Overview
PLUS+1® Mobile Machine Modules
PLUS+1® Mobile Machine Modules are designed to provide flexible, expandable, powerful and cost
effective total machine management system displays for a wide variety of vehicle applications.
PLUS+1® controller products utilize modular designs wherever possible. This modularity extends to
product housings, connectors and control circuitry.
SC Controller Family
The SC0XX-1XX Controller Family has been certified as SIL 2 Capable. This means it is suitable for use in
critical applications up to and including Safety Integrity Level 2. The SIL Rating reflects the level of risk
reduction that the device can provide when used as part of a safety instrumented system.
The third party assessment and certification verifies that the product hardware and software design, the
safety manual, as well as the processes that are used for development, testing, configuration
management, quality control, etc., comply with the 250+ requirements of the IEC 61508 international
standard.
Use of certified devices makes it much easier to design and implement a safety system. It can significantly
reduce cost over the long term and provides an important measure of quality and reliability.
24 and 50 Pin SC Controllers
The SC Controller Family comes in the same sized blue housing.
These modules communicate with one another and other intelligent systems over a machine Controller
Area Network (CAN) data bus. PLUS+1® hardware products are designed to be equally effective in a
distributed CAN system, with intelligence in every node, or as stand-alone control for smaller machine
systems. PLUS+1® systems are incrementally expandable: additional modules can be easily added to the
machine CAN bus to increase system capabilities or computational power.
PLUS+1® modules have input or output pins that support multiple functions. Pins that support multiple
input or output types are user-configurable using PLUS+1® GUIDE software. Refer to product data sheets
for the input/output (I/O) content of individual modules.

Digital/Analog/Resistance/4-20 mA Current (DIN/AIN/ResIN/CrntIN)
When a SC Controller input pin is configured as a resistance/rheostat/temp sensor input, the device will
provide up to 3.76 mA current to an external load (RL) which then can be measured. The equation for
relating AD counts to a given load is: AD counts = (30996*RL) / (RL + 1322). This calculation is solved
internally and the ohms value is available for the programmer. The following Rheostat inputs chart shows
the relationship between AD counts and load resistance in ohms.

Do not connect a digital output to battery+ (back drive) without a series diode.
For each digital output there are two switches in series. One switch is controlled and monitored by the
secondary controller, and one is controlled and monitored by the primary processor. The secondary
controller can monitor the condition of the redundant switch under its control with a digital voltage
feedback signal. Any output can be disconnected from its supply voltage at any time by the secondary
controller with this redundant switch. When the redundant switch is disabled it must remain disabled by
the kernel for 250 milliseconds before the secondary controller's application is allowed to re-enable the
redundant switch. When the redundant switch controlled by the secondary controller is enabled then the
digital outputs can be enabled/disabled as commanded by the primary processor. The primary processor
can monitor the condition of its switch with a digital voltage feedback signal.

Pulse Width Modulated (PWMOUT/DOUT)
All PLUS+1® module proportional outputs are Pulse Width Modulated (PWM). PWM frequency is software
adjustable using PLUS+1® GUIDE. A low frequency dither may also be added with software to some
outputs (see individual module API specifications for PWM outputs that support dither). There are two
modes of PWM operation: open loop and closed loop (current control).
In open loop mode, current can be sourced or sunk (all modules are limited to 8 amps sinking), but the
output is a PWM duty cycle. Current feedback may be monitored in open loop mode, but the output is a
constant voltage, not a constant current. The signal line of PVG valves can be driven with an open loop
PWM. The PWM driving the control signal must be set to 0 at the same time as the digital output driving
the PVE power pin is set to 0.
In closed loop mode, current is sourced and a constant current is maintained by the module's operating
system using internal current feedback. Load impedance must not exceed 65 ohms.
In closed loop mode, the maximum current is limited by measuring the feedback current. There is no
thermal protection. If the maximum current is exceeded, the controller kernel will shut down the output
and latch it. The kernel also limits how quickly the output can be repowered (250 ms). The output cannot
be reset until the command goes to 0 or False (if configured as a digital output).
Refer to individual module data sheets for the maximum allowable output current for each PLUS+1
module.

Notes on CAN Bus installation
Total bus impedance should be 60 Ω.
The CAN transceiver will be damaged by any voltage outside of allowable range, (-7 to +36 Vdc), even

If using shielded cable, the shield must be grounded to the machine ground at one point only; preferably
at the mid-point of the CAN bus. Each PLUS+1® module CAN shield pin must be connected to the cable
shield.
Expansion module CAN Bus loading
System designers incorporating PLUS+1® expansion modules in their applications should be aware of

Caution
PCB damage may occur. To prevent damage to the module all module power supply + pins must be
connected to the vehicle power supply to support advertised module maximum output current capacity.
DO NOT use module power supply + pins to supply power to other modules on a machine.
Lower power mode
This feature gives OEM designers the ability to implement automotive-like features in their machine
control system design. If the lower power mode feature is not implemented, this controller has the same
operating characteristics as any other PLUS+1® controller.
When used as a lower power mode controller, supply power to the module is connected directly to the
battery. Lower power mode initiation is defined by the controller's application software: PLUS+1® GUIDE
programmers define the conditions under which the controller is to put into lower power mode. When in
lower power mode, controller outputs are set to zero, sensor power supply is off and the controller
consumes a small amount of current.

DescriptionMinimumMaximumComment
EEPROM write/erase cycles1 millionMinimum valid over entire operating temperature
range.
EEPROM used in PLUS+1® controllers is rated for one million read/write cycles per sector. Sector size is 32
bits. When a value is written to EEPROM, all 32 bits in a particular sector are always written, regardless of
the size of the size of the saved value. If the value being saved in a sector is less than 32 bits (such as U8,
S16, BOLL) adjacent bits in the same EEPROM sector are rewritten with their previous value. The
implication of this memory property is that if two values are being written to the same memory sector,
the useful life of the sector is determined by the value being written most frequently. If that value
exceeds 1 million read/write cycles, all values in the sector may be compromised if the useful life is
exceeded.

PLUS+1® module mating connectors may be mated 10 times.
Recommended torque for the Deutsch® mating connector retaining fastener on the 50 pin connector is
2.26 N•m (20 lb•in).
Product installation
Mounting
PLUS+1® modules can be mounted in one of three ways:
End (bulkhead) installation
•
Up to 3 units stacked on one another
•
Individually side mounted
•
In each case, care must be taken to insure that the module connector is positioned so that moisture
drains away from the connector. If the module is side or stack mounted, provide a drip loop in the
harness. If the module is mounted vertically, the connector should be on the bottom of the module.
Provide strain relief for mating connector wires.
Caution
Module damage may occur. Use caution when installing modules. Due to the size of the mating
connector wire bundle, it is possible to twist off the end cap of the module if excessive pressure is applied
during the installation of harness strain relief.

Machine diagnostic connector
It is recommended that a diagnostic connector be installed on machines that are controlled by PLUS+1
modules. The connector should be located in the operator's cabin or in the area where machine
operations are controlled and should be easily accessible.
Communication (software uploads and downloads and service and diagnostic tool interaction) between
PLUS+1® modules and personal computers is accomplished over the vehicle CAN network. The diagnostic
connector should tee into the vehicle CAN bus and have the following elements:
CAN +
•
CAN -
•
CAN shield
•
®
Grounding
Proper operation of any electronic control system requires that all control modules including displays,
microcontrollers and expansion modules be connected to a common ground. A dedicated ground wire
of appropriate size connected to the machine battery is recommended.
Hot plugging
Machine power should be off when connecting PLUS+1® modules to mating connectors.
Recommended machine wiring guidelines
1. All wires must be protected from mechanical abuse. Wires should be run in flexible metal or plastic
conduits.
2. Use 85˚ C [185˚ F] wire with abrasion resistant insulation. 105˚ C [221˚ F] wire should be considered
near hot surfaces.
3. Use a wire size that is appropriate for the module connector.
4. Separate high current wires such as solenoids, lights, alternators or fuel pumps from sensor and other
noise-sensitive input wires.
5. Run wires along the inside of, or close to, metal machine surfaces where possible. This simulates a
shield which will minimize the effects of EMI/RFI radiation.
6. Do not run wires near sharp metal corners. Consider running wires through a grommet when
rounding a corner.
7. Do not run wires near hot machine members.
8. Provide strain relief for all wires.
9. Avoid running wires near moving or vibrating components.
10. Avoid long, unsupported wire spans.
11. All analog sensors should be powered by the sensor power source from the PLUS+1® controller and
ground returned to the sensor ground pin on the PLUS+1® controller.
12. Sensor lines should be twisted about one turn every 10 cm [4 in].

13. It is better to use wire harness anchors that will allow wires to float with respect to the machine rather
than rigid anchors.
14. Electronic modules should be grounded to a dedicated conductor of sufficient size that is connected
to the battery (-).
Electronic components welding guidelines
Remove electronic components from the machine before any arc welding. The following is
recommended when welding on a machine equipped with electronic components:
Turn the engine off.
•
Disconnect the negative battery cable from the battery.
•
Do not use electronic components to ground the welder.
•
Clamp the ground cable for the welder to the component that will be welded as close as possible to
•
the weld.
PLUS+1® USB/CAN Gateway
Communication (software uploads and downloads and service and diagnostic tool interaction) between
PLUS+1® modules and a personal computer (PC) is accomplished using the vehicle's PLUS+1® CAN
network.
The PLUS+1® CG150-2 USB/CAN gateway provides the communication interface between a PC USB port
and the vehicle CAN bus. When connected to a PC, the gateway acts as a USB slave. In this configuration,
all required electrical power is supplied by the upstream PC host. No other power source is required.
Refer to the PLUS+1® GUIDE Software User Manual, literature number 10100824, for gateway set-up
information. Refer to the CG150-2 USB/CAN Gateway Data Sheet, literature number L1412468, for
electrical specifications and connector pin details.
