E1 Brain Board

1: Introduction

E1 digital and E2 analog brain boards are intelligent I/O (input/output) processors that communicate with a host computer and also perform control functions at each point of I/O.

Designed as drop-in replacements for Opto 22’s B1 and B2 brain boards, the E1 and E2 have the same Optomux and serial network capabilities, but they offer significant new features: Ethernet support, additional protocol support, and migration and expansion opportunities. For example, you can use PAC Project™ software applications with E1 or E2 I/O systems to control, monitor, and acquire data.

E1 and E2 brain boards can communicate using Optomux over serial and Ethernet, and using Opto 22’s OptoMMP™ protocol over Ethernet. OLE for Process Control (OPC) and Modbus/TCP clients can readily obtain data from the system over Ethernet. For detailed information on protocols and system architecture, see

Chapter 3: Architecture and Communication.



E1 Brain Board

The E1 brain board is a digital-only processor that can be used with a variety of input/output (I/O) modules and mounting racks. The E1 supports up to 16 I/O modules.

In addition to On/Off control, the E1 brain board provides the following digital functions:

• Read/write to point

• Input latches

• Counters

• Pulse duration measurement

• Pulse generation

• Time delays

• Watchdog timer

For detailed descriptions of E1 features, see

About E1 and E2 brain boards: You can configure E1s and E2s like any other I/O unit if you have E1/E2 firmware R1.2a (and higher) and PAC Project 9.5000 (and higher). Also, if a SNAP PAC controller communicates with the E1 or E2, the controller must have PAC firmware R9.5a (or higher) to use this simplified configuration method. If you are not using these firmware and software versions (or if you prefer to use the previous method to reconfigure existing E1s or E2s), see

I/O Configuration for E1 an E2 Brain Boards (form 1576).

Each E1 feature is described below.

Read/Write to Point—The E1 can read the value of any input

or output point and turn digital output points

on or off.

Input Latches—When the value of a digital input point changes from off to on, an on-latch can be set.

While the value of the point may return to off, the on-latch remains set until cleared, as a record of the change.

Similarly, an off-latch can be set when the value of a digital point changes from on to off, and it remains set until cleared. See note 2 in the table above.

Latching is different on an E1 depending on the protocol used with the brain board. When the E1 is used with the Optomux protocol, only one latch is available and you must configure it to be an off-to-on latch or on-to-off latch. When you use an E1 with OptoMMP or Modbus/TCP, however, both types of latches are automatically available for each point, and no configuration is required.

Counters—Digital input can be used as a counter, counting the number of times the input changes from off to on.

Pulse Duration Measurement (using the Optomux protocol)—Any or all of the input points can function as pulse duration timers. Either on or off pulses can be timed with a resolution of 10 milliseconds.

Pulse Generation (using the Optomux protocol)—The E1 can be instructed to output a specific number of pulses (with programmable period) at any output point. Continuous square waves can also be generated.

E1 and E2 User’s Guide

E1 AND E2 FEATURES AND SPECIFICATIONS

Time Delays (using the Optomux protocol)—Any or all output points can function in time delay mode. Outputs can be set to operate with four types of delays:

• Delay before turning off

• Delay before turning on

• Pulse on

• Pulse off

Time delays are programmable with a resolution of 10 milliseconds.

Watchdog Timer—You can set a watchdog timer to monitor communication with the PC or other host device. If the watchdog timer is set via the serial port, then any serial activity will trigger the watchdog (including communications to other devices). If it is set via the Ethernet port, then only Ethernet activity directed to the respective E1 or E2 will trigger the watchdog. If the watchdog isn’t triggered for the length of time set, the brain board automatically sets designated I/O points to the values you have determined. This action makes sure the process is brought to a safe state if communication fails.

I/O Configuration for E1 an E2 Brain Boards (form 1576).

Each E2 feature is described below.

Read/Write to Point in Engineering Units (using OptoMMP)—The E2 can read the value of an input point and send a value to an output point in engineering units, such as millivolts or milliamps.

Read/Write to Point in Counts—The E2 can read the value of an input point and send a value to an output point in 12-bit counts.

This is especially useful when integrating with existing Optomux systems. The Optomux protocol will return counts in a range of 0–4095.

CHAPTER 1: INTRODUCTION

The OptoMMP protocol returns counts based on how the E2 was configured:

• Modules configured directly as G1 modules (new method; requires E2 firmware R1.2a or higher and PAC

Project 9.5 or higher) will report counts as G1 counts (0–4095 nominal range).

• Modules configured as similar SNAP modules (old method using form 1576) will report counts as 0–

25000 or -25000 to +25000.

Input Averaging (using the Optomux protocol)—The E2 can be instructed to average the values of successive readings.

Minimum/Maximum Values (peak/valley recording)—The E2 automatically keeps track of minimum and maximum count values for each input. You can read these values at any time, and you can reset min/max values.

NOTE: The values returned for temperature modules will be counts, not linearized temperature values. See Read/Write to Point in Counts, above, for count values.

High/Low Range Testing—The E2 tests for the high and low limits (range) for the specified input points, and sets a flag if values exceed the specified range

Offset and Gain Calculations—The brain board can calculate offset and gain for analog input points. If a 0 VDC to +5 VDC input receives signals that are slightly off (not exactly 0 VDC at the lowest point, for example), the offset and gain can be calculated so that values will appear accurately.

NOTE: To calibrate analog points, use PAC Manager. See form #1714, the Legacy Edition PAC Manager User’s Guide.

Waveform Generation (using Optomux)—Square waves, triangle waves, and ramps can be generated at any output point with programmable rates.

2: Installation

Use this chapter to install E1 and E2 brain boards. If you need more information on how to integrate E1s and E2s with your system, see Chapter 3: Architecture and Communication.

WHAT YOU WILL NEED

To install an E1 or E2, you need the following items:

• PC running Microsoft

protocol installed, and a valid IP address. The PC must be on the same subnet as the brain board.

• Serial cable for a serial network. For an Ethernet network, use Category 5 Ethernet cable. (For more

information on cables, see page 22.)

• E1 or E2 brain board

• I/O modules and mounting racks (See compatible I/O modules and mounting racks on page 22.)

• Power supply (See page 23.)

• Voltmeter

• Screwdriver

Windows® 2000 or higher, with a 10/100 MB Ethernet adapter card, the TCP/IP

INSTALLING SOFTWARE

The software for E1 and E2 brain boards is available on the Opto 22 website.

• The E1 product page lists all E1 software in the Downloads tab.

• The E2 product page lists all E2 software in the Downloads tab.

MOUNTING THE BRAIN BOARD

Racks vary in shape and design. The combination of rack, modules, and brain board (called the I/O unit) can be mounted in any attitude on any flat surface.

To ensure reliable and trouble-free communications, the following is recommended:

• Use twisted-pair wires for the serial communications wiring. See page 22.

• Keep communication and DC power wiring separate from any high-voltage field wiring.

Steps for mounting:

1. If you are replacing an existing B1 or B2 brain board, turn off the power to the rack and carefully remove

the B1 or B2 from the rack.

2. Carefully plug the E1 or E2 brain board into the mounting rack using the 50-pin connector.

E1 and E2 User’s Guide 13

MOUNTING THE BRAIN BOARD

E1 brain board/rack combination. As shown in the G1/Standard example below, the brain board extends out past the end of the rack when used with G4, G1, and Quad Pak I/O racks. For integral racks, which have permanent I/O circuitry built in, the brain board is inserted in the other direction, covering the rack.

E2 brain board/rack combination

3. Place the I/O unit as close as possible to the controlled device to minimize wiring costs and noise for

analog modules. When installing units next to each other, leave sufficient space between units for wiring.

4. For maximum physical strength, secure the brain board’s permanently attached standoffs. Also secure standoffs on the rack, if available.

E1 and E2 User’s Guide

CONNECTING THE POWER SUPPLY

CHAPTER 2: INSTALLATION

1. Using size 14 AWG or larger wire, connect 5-volt power to the + 5V and GND connectors on the

mounting rack. If the + 5-volt supply is used by more than one unit or by other devices, make sure the voltage at each rack is 5.1–5.2 VDC. Use a consistent color code from the power supply to all brain boards to prevent wiring errors. See Opto 22 form #1271, Using Power Supplies with Opto 22 Systems, for more information on power wiring and voltage adjustments.

EXCEPTION: If an Opto 22 PBSA/B/C power supply is used with digital racks, the + 5 VDC logic connection is made by the supply when it is screwed to the rack. In this case, the only connection required is the 120 VAC (220 VAC or 10–28 VDC depending on supply type) connection to the PBSA (or PBSB or PBSC) supply.

2. You can use either separate or combined 5.1–5.2 VDC and ± 15 VDC (± 0.25 VDC) supplies to provide

power to analog racks. If you use a multiple-output supply, make sure that the 5 VDC RETURN line is separate from the 15-volt COMMON line to maintain module isolation.

3. Route the +5-volt and ±15-volt wires away from any high-voltage field wires. Make sure there is only one

earth ground connection per network, typically at the host site. If the ground connection is at the host site, make sure none of the power supplies is grounded. This

method prevents ground loop problems due to offset voltages appearing between multiple ground points.

4. IMPORTANT: Check polarities of all power supply connections before applying power.

Incorrect polarity can damage the brain board and I/O modules.

NOTE: If the brain board is connected to an Ethernet network, before powering up see the section about assigning an IP address in form #1714, Legacy Edition PAC Manager User’s Guide.

E1 and E2 User’s Guide

CONNECTING THE E1 AND E2 TO EARTH GROUND

E1 grounding PEM E2 grounding PEM

CONNECTING THE E1 AND E2 TO EARTH GROUND

In installations where electrical noise is a concern, the E1 and E2 each provide a grounding point to improve noise immunity. Using 18 AWG, connect the insulated wire from the grounding PEM to the point where the earth ground is connected. Each brain should have a separate wire to connect to ground. Each grounding point should be tied to a single point earth ground.

INSTALLING I/O MODULES

1. Turn off all power to the unit and to the field devices. IMPORTANT: All power must be turned off before installing or removing I/O modules.

2. Install input and output modules in any rack position. Compatible modules are shown in the table on

page 22. For specifications and wiring information on modules, see the module’s data sheet.

3. Depending on the networks you are using, continue with the following: – “Connecting to a Serial Network,” below – “Connecting to an Ethernet Network” on page 21

NOTE: You can use both serial and Ethernet networks simultaneously. E1 and E2 brain boards are set by default to communicate on both networks.

CONNECTING TO A SERIAL NETWORK

Wiring Serial Communications and Power

A complete connection at each brain board consists of 10 wires as well as an overall cable shield: two twisted pairs and a common coming from the computer or previous brain board, and two twisted pairs and a common going to the next brain board. To ensure reliable communications, we recommend the following:

• Use shielded twisted-pair wires for the communications wiring. (See recommended cables on page 22.)

• Route the communication and DC power wiring separately from any high-voltage field wiring or AC

power wiring.

• Make sure the communications COM terminals on each rack are connected.

E1 and E2 User’s Guide

CHAPTER 2: INSTALLATION

The following graphic shows standard and alternate wiring diagrams. When wiring a series of brain boards, always think of the previous brain board as the host.

Setting Jumpers (Serial Only)

Jumpers in groups A and B are set during initial configuration:

• Group A jumpers set repeat or multidrop mode, and termination.

• Group B jumpers set baud rate, 2-pass or 4-pass message, and address.

For an easy way to see which jumpers to set, go to our website and use the E1/B1 Brain Jumper Configurator or the E2/B2 Brain Jumper Configurator.

Note: If you have an existing brain and need to know how it is currently configured (for example, if you are replacing a B1 with an E1 and need to configure them the same), use these interactive demos:

For information on using jumpers to reset the brain board, see “Resetting the Brain Board to Factory Defaults”

on page 35.

Also see “Jumper Tips” on page 54.

NOTE: When the E1 or E2 is powered up, it periodically reads the jumpers. You can change the jumpers at any time and the firmware will detect the change and reconfigure accordingly.

1. Set the jumpers in Group A for repeat or multidrop mode, and proper termination and biasing.

Multidrop—When wiring a multidrop communications cable, keep in mind that the cable is a

high-speed data-transmission line. To reduce reflections, make sure the line is terminated properly at both ends and that all stubs are less than three inches long.

Repeat—In this configuration, each brain board acts as a repeater, allowing up to 5,000 feet between units. Since a power failure at any unit breaks the communications link, battery backup is recommended.

NOTE: You cannot mix units operating in repeat mode and units operating in multidrop mode on the same network.

c. Set the address using jumpers 0–7 on Group B, according to the following chart. Each brain board

on the same network must have a unique address. Addresses do not need to be sequential.

To connect to an Ethernet network, see form #1714, the PAC Manager User’s Guide, Legacy Edition.

IMPORTANT: If you are communicating only on an Ethernet network (no serial connections), make sure that

Group A jumpers on E1 and E2 brains are set for multidrop mode/middle of link (see diagram below).

If jumpers are not set in this way, the RS-485 communication lines may cause interference.

Security

When designing your Ethernet network, be sure to consider security as required for your application. You can use PAC Manager to limit access to Ethernet-based I/O units, either by allowing access only from specific computers or other devices on the network (IP filtering), or by limiting access to specific protocols that are used with the I/O unit (port access).

See form #1714, the Legacy Edition PAC Manager User's Guide, for more information on security.

SYSTEM COMPONENTS

This section gives additional information on some items listed in “What You Will Need” on page 13.

I/O Modules and Mounting Racks

The brain board plus the mounting rack and modules are often referred to as the I/O unit. Choose compatible I/O modules and mounting racks from the following tables.

I/O modules Digital mounting racks I/O modules Analog mounting racks

Cable

For serial (RS-422/485) communications, the following cables are recommended. Cables listed are 24-gauge, 7x32 stranded, with 100-ohm nominal impedance and a capacitance of 12.5 pF/ft. If you use other cables, they should have a nominal impedance of 100–120 Ohms and a capacitance of less than 15 pF/ft.

We also recommend that you choose a cable with one more pair than your application requires, so you can use one of the extra wires, rather than the shield, for the signal common.

Four-pair Three-pair

• Belden P/N 8104 (with overall shield)

• Belden P/N 9728 (individually shielded)

• Belden P/N 8164 (individually shielded with overall shield)

• Manhattan P/N M3477 (individually shielded with overall shield)

• Manhattan P/N M39251 (individually shielded with overall shield)

• Belden P/N 8103 (with overall shield)

• Belden P/N 9730 (individually shielded)

• Belden P/N 8163 (individually shielded with overall shield)

• Manhattan P/N M3476 (individually shielded with overall shield)

• Manhattan P/N M39250 (individually shielded with overall shield)

For Ethernet communications, use a Category 5 Ethernet connection to a standard 10BASE-T or 100BASE-TX Ethernet network. If you need a direct connection to a PC, use an Ethernet crossover cable.

CHAPTER 2: INSTALLATION

Power Supply

Choose the power supply appropriate for the rack. E1 and E2 brain boards require 5.0–5.2 VDC at 0.5 amps (see note). Although it is possible to distribute DC from a common power supply to several locations, better noise immunity is obtained by having separate power supplies for each I/O unit. For more information, see Opto 22 form #1271, Using Power Supplies with Opto 22 Systems Technical Note.

NOTE: For all Opto 22 products that require 5 VDC, we recommend adjusting the power supply so that the Opto 22 products are receiving 5.10 –5.20 VDC. This recommendation is based on years of experience and will eliminate many startup and maintenance issues.

Analog racks also require +15 VDC and -15 VDC (± 0.25 VDC) to power the analog I/O modules. The amount of power required depends on the type and number of analog I/O modules that are plugged into the rack. Power requirements for each of the analog modules are included in the module specifications.

Analog racks also provide terminals for a separate +24 volt supply that can be used for powering 4–20 mA current loops using 4–20 mA analog I/O modules. For this type of application, the +24 volt supply is required in addition to the supplies mentioned above. Refer to the module data sheets for information on wiring 4–20 mA modules with a loop supply.

The current requirements given for the output modules are only for the modules. To determine what size power supply is needed, add the load requirements for each module to determine total power supply requirements.

NOTE: Use only isolated supplies. Isolated supplies reduce the risk of ground loops in the communication wiring. Do not connect the power supply’s DC common to earth ground. Linear power supplies are recommended. See Opto 22 form #1271, for more information.
