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.

Each PLUS+1® module input pin supports one of the above functional types. For pins with multiple functions, input configurations are user programmable using PLUS+1® GUIDE templates.

Digital/Analog (DIN/AIN), A/D Refresh Rates

Multifunction pins that are configured to be DIN are subject to the same update rates as the analog input function for that pin. Debounce is not used, as hysteresis is built into the function. The time to recognize a transition is dependent on the timing of the switch activation and the sample rate.

If the frequency goes to zero, the data will not decay over time, it will be updated once a new pulse is seen, or times out. It is possible to monitor the count of pulses to know when the frequency reading is updated.

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.

LEDs

There are two LEDs on every PLUS+1® module, one red and one green. Both are under application software control of the primary processor. Before the primary processor's application software starts running, the green LED will be on and the red LED will be off.
Each LED light pipe will have an alternate yellow color which the application software will not have access to. These alternate yellow colors will be used to indicate low-level software and/or hardware failures. The yellow LED shared with the green LED light pipe will be controlled by the primary processor, and the yellow LED shared with the red LED light pipe will be controlled by the secondary controller. When either yellow LED is enabled the signal will override its shared green or red LED.

Up to 1 MBps
No internal termination

CAN system design

All PLUS+1® modules have CAN ports that conform to CAN 2.0B specifications, including CAN shield.
Warning
Unintended movement of the machine or mechanism may cause injury to the technician or bystanders. Machine performance may be impaired if CAN communications are disrupted by electrical fields in excess of 30 V/m between 20 and 30 MHz. To prevent potential unintended machine movement and to meet EMC requirements, a shielded CAN bus must be used to achieve 100 V/m immunity.

Specifications for terminating resistor

Each end of the main backbone of the CAN bus must be terminated with an appropriate resistance to provide correct termination of the CAN_H and CAN_L conductors. This termination resistance should be connected between the CAN_H and CAN_L conductors.
Specifications
Description Units Minimum Maximum Nominal Comment
Resistance 110 130 120 Minimum power dissipation 400 mW
(assumes a short of 16 Vdc to CAN_H).
Inductance µH 1

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 with a very short pulse.
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 PLUS+1® CAN bus loading and controller memory usage during system design. Each expansion module is associated with a PLUS+1® controller and uses part of the controller's memory resources for inter-module communications. The table below can be used to estimate system CAN bus loading and the memory impact of I/O modules on their associated controller.

Power

Battery power must be supplied to designated power-up digital inputs, since the controller's 3 to 12 Vdc regulated power supply is not available when the controller is in lower power mode.

Module supply voltage/maximum current ratings

PLUS+1® modules are designed to operate with a nominal 7 to 36 Vdc power supply. The modules will survive with full functionality if the supply voltage remains below 36 Vdc.

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.

Specifications
Description Minimum Maximum Comment
EEPROM write/erase cycles 1 million Minimum 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.

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.
