1 INTRODUCTION

1.1 Scope

This document is the User Manual for the Allen Bradley serial communication driver

firmware for the Emerson DeltaV Control System; it provides information required to install,
configure, and maintain the Allen-Bradley driver firmware on the DeltaV Programmable
Serial Interface Card (PSIC). The reader should be familiar with the DeltaV controller
system and the Allen-Bradley PLC-5 Family of Programmable Logic Controllers, the Allen­Bradley SLC-500 Family of Serial Logic and/or Controllers Allen-Bradley PLC-3 Family of
Programmable Logic Controllers.

A DeltaV Programmable Serial Interface Card with the Allen-Bradley driver may

communicate with the Allen-Bradley PLC-5 Family of Programmable Logic Controllers, the
Allen-Bradley SLC-500 Family of Serial Logic Controllers and/or Allen-Bradley PLC-3 Family
of Programmable Logic Controllers within the constraints delineated herein. In general for
driver version 1.0, the Allen-Bradley family of SLC-500’s can communicate using the same
command set used to communicate with the PLC-5 family. The SLC5/01 communicates
via the PLC2 basic commands, so only file N9 can be accessed with the SLC5/01. For
driver version 1.1, a specific command type was added to read/write SLC5/XX Input and
Output tables. The previous release of the driver, version 1.4, expands on the SLC
specific command to read/write all SLC tables. Additionally, this version allows you to
select communications using Half Duplex/CRC. Note that the default is Full Duplex/BCC.
This release, version 1.7, provides support for PLC-3 file read and write, and ControlNet
extra hop addressing when using the Allen Bradley 1770-KFC15 gateway device.

The section Document Format briefly describes the contents of each section of this manual.

System Specifications outlines hardware and software requirements for the Allen-Bradley
Driver (P1.7) firmware. Related Documents lists other documents used to prepare this
manual.

2 THEORY OF OPERATION

As part of the serial interface port license, a standard Modbus protocol is installed on the

DeltaV PSIC prior to customization. The PSIC needs to be flash upgraded from the
Modbus protocol to the Allen-Bradley protocol before operation.

The Allen-Bradley serial driver implements DF1 protocol. It communicates with PLC-3,
PLC-5 or SLC5/XX devices on the DH+ network through either a 1785-KE or 1770-KF2
communication modules. These modules convert the DF1 serial protocol to the DH+
network protocol. The switch settings must be configured properly for the RS-232 or RS­422/485 prerequisite for proper operation.

The Allen-Bradley Driver communicates with the PLC and updates emulated DeltaV I/O

with the data received from the PLC. The primary functions of the driver are listed below:

· Performs data and message handling between DeltaV and PLC-3 / PLC-5 / SLC5/XX.

· Sends messages to PLC-3 / PLC-5 / SLC5/XX from DeltaV

· Processes reply information and updates the corresponding emulated DeltaV I/O

channels

· Update emulated input channel status and Data Block status to indicate the

communication state of PLC-3 / PLC-5 / SLC5/XX.

· Checks validity of messages received by PLC-3 / PLC-5 / SLC5/XX.

Upon proper installation and configuration of the Allen-Bradley driver within the

DeltaV/PSIC system, communications with a properly configured Allen-Bradley PLC-3 /
PLC-5 or SLC5/XX may proceed.

There are a maximum of 16 Datasets (DS) per port, with a total of 32 per PSIC. The

maximum number of data elements per Dataset that can be supported by the PSIC
depends on the data file type. Note that the number of supported Datasets does not
change. The following table describes this correlation:

Dataset Data File Type

Boolean 100
Discrete 100
8-bit signed integer 100
16-bit signed integer 100
32-bit signed integer 50
8-bit unsigned integer 100
16-bit unsigned integer 100
32-bit unsigned integer 50
Floating point 50
String 1

The DeltaV PSIC is the master in all communications. It polls each input device and

requests data values on a message by message basis. The output is performed when a
new value is to be written to the devices. The PSIC constantly scans the configured input
Datasets for new values and updates the database. Upon a change of value in the output
Dataset, the PSIC will finish the current input scan and suspend the input process. It will
service all the output requests before resuming the input process.

With the Allen-Bradley driver installed, the “Advanced” tab under port properties will allow

selection of the configuration option for the port to act as a slave. This Allen-Bradley driver
does not support slave functionality, so this configuration option is not valid.

The Allen-Bradley driver supports PLC-5 Logical ASCII and binary addressing, and

SLC5/XX Protected Typed Logical addressing.

NOTE: When addressing registers, DeltaV PSIC register numbers are 1 based,

whereas PLC and SLC registers are 0 based.

3 Downloading the firmware

To begin installation of the Allen-Bradley driver, create a folder on the hard drive. The

preferred location for the folder is at C:\DeltaV\Ctl\ProgSerial\AllenBradley, although any
location will work.

Next, copy the eight files from the diskette provided. Those files are:

1200.idf
IO_Compatibility.csv
AllenBradleyApp.sdf
AllenBradleyApp.hex
SerBoot.hex
SerReleaseApp.hex
StandardModbusApp.sdf
Ab-manual.pdf

Once the files have been copied to the appropriate folder, the process of downloading the

driver can begin:

1. Start the “Controller Upgrade Utility” from the DeltaV/Installation menu

2. Select “Upgrade I/O Modules” and engage the “Next” button

3. From the controller list select the controller to which the serial card is attached and
enter the “Next” button

4. Find the list of I/O cards connected to the selected controller. At the bottom of the
screen there is an upgrade file path displayed. Enter the “Browse” button and browse
to the directory containing the Allen-Bradley driver. This should be
C:\DeltaV\Ctl\ProgSerial\AllenBradley. Engage the “OK” button to return to the I/O card
selection screen

5. Select the Serial Card or Prog Serial Card to be upgraded

6. If the user chooses a standard Serial Card to be upgraded then the card will
automatically be upgraded as soon as the “Next” button is entered. If the user chooses
a Prog Serial Card, the user will be prompted for the SDF file to use. Browse to and
select the proper SDF file. Press the “Open” button followed the “Next” button to start
the upgrade process

7. The Flash Upgrade process should start and the progress will be displayed in the
progress window. An upgrade complete message will be displayed upon completion of
the upgrade.

8. If a standard Serial Card was used for this installation, delete the Serial Card in DeltaV
Explorer and Auto-sense the new Prog Serial Card. Installing a special driver changes
the card from a standard Serial Card to a Prog Serial Card.

4 CONFIGURATION INFORMATION

4.1 Channel Attributes Block of PSIC

This section describes the steps necessary to configure the DeltaV PSIC and the Allen-

Bradley PLC such that communications may be invoked

Channel Attributes Block

For the PSIC configuration, there is one channel attributes block per Dataset. There can
be up to 16 Datasets configured per port for a total of 32 Channel Attribute Blocks per
Serial Card. Each Channel Attribute Block contains all the configuration information for a
single configured PSIC Dataset.

The four following attributes (page 9) are unique to the Allen-Bradley Data Highway serial
card. All other values are as per the standard serial interface card. Information for the
standard serial interface card can be found in DeltaV Books Online, under the title “Using
Serial Data Control Strategies”.
