CP382 Introduction

1. Introduction

1.1 Product Overview

The CP382 digital output controller has been designed to provide a large number of automatically controlled, flexible digital outputs within a ruggedised board equipped with features for electrical protection. The flexibility is due to the fact that the 24 channels provided are organised into 3 separate clusters of 8 channels each, allowing the user to configure up to 3 different voltages as required. Reliability is assured by features which include overtemperature thermal shutdown, overcurrent and undervoltage protection. Use of the widely available D-sub 6 2 front panel connector means that the board may be used in a broad range of application fields. On the software side the board may be used with all major operating systems.

This product is part of a comprehensive concept whose goal is to provide Comp actPCI system integrators with a complete range of I/O products which include the functions of analog input, analog output, digital input and digital output implemented as separate integral boards. This concept ensures the maximum degree of system design flexibility thus allowing for the ef ficient and effective usage of available resources..

Introduction CP382

1.2 Board Overview

1.2.1 Board Introduction

The CP382 is a digital output board which provides twenty-four output channels grouped into three clusters of eight channels each. The major components involved are the front end High Side Driver switches (HSD = High Side Driver switch), output signal optoisolation, and the Digital Output Process and Communications (DO ProComm) controller which is realized within a Field-Programmable Gate Array (FPGA). The DO ProComm Controller is designed for effective and efficient control of the digital output signals as well as providing interfacing with the CPCI system controller.

Digital output requests from the System Controller are processed accordingly by the DO ProComm controller and are then routed to the HSD’s which in turn create the actual digit al output utilizing the external supply voltage as the power source.

An external reset input is provided to simultaneously switch off all the outputs per cluster and sets all the High Side Driver Switches to open. Each cluster has its own separate reset signal input.

This reset can be used by the application to keep the inputs low after a fault condition.

1.2.2 Board Specific Information

Specific board components involved in the digital output process:

• One front panel connector (62-pin, female, D-sub type)

• 6 HSD switches (4 channels per switch, 2 switches per cluster)

• Optoisolation for each output channel

• One FPGA (the DO ProComm controller)

• One CompactPCI bus connector (J1, board to backplane, 132-pin, female, six row)

• One EEPROM (CapROM)

Page 30

Functional Description CP382

2.1.1 High Side Driver Switches

The High Side Driver switches (HSD switches) are able to drive inductive, capacitive or resistive loads. Diagnostic information for the system master and extensive use of electrical protection are among their main characteristics.

The HSD switches (type L6376 manufactured by SGS THOMSON) constitute the most important part of the front end. The L6376 switch realizes a QUAD intelligent power switch which adapts the digital output signals to the prevailing voltage and current levels and also provides corresponding mechanisms to protect against undervoltage, overcurrent and overtemperature.

The output voltage level is adapted to the external supply volt age for high level and for low level output voltage respectively via the integrated FET transistor output stage within the HSD switch. The HSD switch implements a clamp diode for inductive load driving.

The voltage source for the CP382 front end is implemented using an external voltage source (nominal +24V, also in the range +9.5V to +35V).

The input signals to the HSD switches are derived from the system side, directly from the outputs of the optocoupler devices.

2.1.2 Optoisolation

The process side is galvanically isolated from the system side. The process side of the board is separated from the system side by a bank of optocouplers which serve to protect the system side from any excess voltages or voltage spikes.

2.1.3 DO ProComm Controller

The DO ProComm controller is responsible for supervising and controlling the digit al data output process and maintaining communication with the CompactPCI system master . Applications address the CP382 through its software driver interface within the system master where by the controller accepts requests from the driver and executes them accordingly . Digit al data from the system master is processed through the DO ProComm controller and then routed to the HSD switches.

Page 31

CP382 Functional Description

2.1.4 System Interfaces

The CP382 provides interfacing capability for the following system elements:

• Front Panel connector

• CompactPCI bus

Digital outputs, external voltage, and external reset are routed via the CON2 connector. Interfacing to the CompactPCI bus is accomplished via the CON1 connector . Test a nd program development is supported by the CON3 connector.

External supply each Cluster: The connection for the external supply (+24V DC [9.5V to 35V] each cluster) is realized by re-

served/ defined pins within each cluster at the front panel connector CON2.

Important...

In addition to supplying the current for the logic parts of the power switches which are linked to the digital outputs, the exte rnal volt age su pplies also have to supply the current for the 8 digital output loads per cluster.

External reset for each cluster: The digital outputs will be brought to zero output level on power-up. In addition to the reset by

software, the reset-lines (one each cluster) are routed to the front panel.

2.1.5 Monitor and Control

Various monitor and control functions are available for the operation of the CP382. T wo LED’s are available for operator interaction. There are also system failure indicators available. In addition, applications have access via the System Master driver software to board specific registers.

2.1.6 Software

Driver software is available for the System Master application software.

CP382 Functional Description

2.4 CapROM EEPROM

The CapROM is a 4 kBit (512 byte) EEPROM which provides the capability t o store board control relevant information to allow software configuration of the CP382.

2.5 Monitor and Control (M/C)

The front panel of the board is equipped with two LED’s for user defined purpose s. One green (RUN) and one red (F AIL) have been placed on the front panel in anticipation of their most likely use. However they are freely programmable, the indicators being selected by the system master (access to the hardware debug register (hdr)).

The system failure indicators regarding undervoltage, overcurrent and overtemperature are made available to the DO ProComm controller . These indicators are aut omatically reset by the HSD switches once the conditon has been corrected and the output returns to normal mode.

An input signal Halt/Reset is available to set an inactive state for each individual cluster and also to shut down each individual cluster during operation as necessary.

4. Configuration

This chapter provides information for configuring the CP382 board for operation.

4.1 Jumper Settings

The CP382 does not have any jumpers which require configuring.

4.2 Digital Output Signal Properties

In addition to the output signal type and its range, which have been specified in chapter 1, p aragraph 1.3.1, system integrators must be aware of certain output configuration requirements for the CP382. The following paragraphs provide some information regarding individual connection configuration requirements.

4.2.1 Channels

The CON2 connector of the CP382 is designed so that there is one output pin per channel. This is illustrated in Figure 2-2, which shows the front panel connector pinout, with the 24 channels shown starting at the top of the connector with channel 0 (cluster A).

The following sections address the basic requirements.

4.2.2 Connection of External Supply

The CP382 requires an external voltage for operation. The input connection for this voltage is realized via the 62-pin front panel connector CON2. The

pinout of this connector is provided in table 2-1. The three clusters have split supply planes, so that it is possible to provide each cluster (clus-

ters A, B and C) with a separate volt age, with different voltage values within the defined range (see also table 1-1).

Note...

Each channel has a maximum current of 0.5 A. In situations where many channels are carrying a high current, separate, larger gauge cables for the external power supply should be used.

CP382

Note...

The voltage source for each cluster is an external supply (in the range +9.5V to +35V DC). Therefore the GND reference for the digital output is the ground potential of this external voltage supply.

Important...

Individual outputs should not be cascaded as it cannot be guaranteed that power sharing will be proportional, due to the transistor characteristics of each HSD (HighSide Driver switch).

4.2.4 Connection of Inductive Loads

The outputs have internal clamping diodes for each channel, which are able to demagnetize inductive loads.

The limitation is the peak power dissipation of the digital outputs at the front end. Where there are large loads or if there is the possibility that additional loads require demagnetization simultaneously, external demagnetization circuits are required.

There are two possible topologies for the demagnetization versus ground or versus supply voltage.

Note...

For more detailed information about the external demagnetization circuits, please refer to the L6376 datasheet referenced under chapter 1.8 Related Publications.

4.3.5 Programming the Board Capabili ty ROM

The Board Capability ROM contains all the board data necessary to identify board, version, optional features, etc., and to setup the basic software. The BCR is implemented using a 4 KBit serial EEPROM of the type Microchip 93LC66.

(The contents list of the BCR is not described here.)

The serial interface of the device has been realized in hardware resulting in a very simple register based programming interface with command, control, st atus and dat a registe rs. All protocol and serial timing specifications are resolved by hardware.

Programming of the BCR is undertaken as follows: The control word is written into the ROM Control Register including command opcode and internal address. Then optional data (in case of Write action) is written into the ROM Data Register. Command execution is started by setting the St artbit in the ROM Command Register. Then Ready/Busy must be polled in the ROM Status Register. After reaching Ready status, the next command can be set up and data (in case of Read action) can be fetched from the ROM Data Register.

CP382 System Considerations

5. System Considerations

5.1 Introduction

In addition to the basic specification requirements for the CP382 which have been addressed in chapter 4, system integrators need to be aware of the overall system environment and the application needs when designing the interfacing to the CP382. The following chapters addre ss a number of more apparent considerations which should be addressed but certainly not all of the possible situations which may be encountered. Many of the considerations presented here are recommendations, but some are definite requirements if the CP382 is to successfully achieve its purpose.

5.2 General

Considerations:

1. Care must be t aken to ensure that proper grounding concept s are followed , and that the integrity of the grounding system within the application be maintained.

2. Where possible input wiring length should be kept as short as possible.

5.3 Shielding

Considerations:

1. Input cable shielding in general is recommended.

2. The requirement s for shielding can be seen primarily as a function of the system design and environment, but empirical results must also be considered.

3. The CON2 connector has a metal housing which is connected to the CP382 shield and is isolated from the system ground.

4. Ensure that if shielding is used that it is not in anyway connected to the system ground.

5.4 External Power Supply

Considerations:

1. Voltage sources presented to the CP382 must be within the ranges spe cified in ch apter

1.3.1 or erroneous results will occur as well as possible damage to the CP382.

2. In addition to supplying the current for the logic parts of the power switches which are linked to the digital outputs, the external voltage supplies also have to supply the current for the 8 digital output loads per cluster.

5.5 Cable Interfacing

If necessary , cabling to the CP382 CON2 connector should be physically fixed to prevent strain on the CON2 connector.

Warning!

Each channel has a maximum current of 0.5 A. In situations where many channels are carrying a high current, separate, larger gauge cables for the external power supply should be used.
