4.6 Setting the I/O Configuration

The I/O configuration determines the type of data sent to the drive.
This is a two-part process: enabling/disabling the data transmitted
between the module and the drive, and identifying the data
transmitted between the module and the master (i.e., scanner).

Step 1. Enable or disable the data transmitted between the

module and the drive by setting the bits in module
parameter 12 (DPI I/O Config).

A “1” enables the I/O. A “0” disables the I/O. Bit 0 is the
right-most bit. In figure 4.5, it is highlighted and equals
“1.”

Step 2. If Logic Command/Reference is enabled (default),

configure the parameters in the drive to accept the Logic
Command and Reference from the module. For example,
set Speed Ref A Sel (SP600 drive parameter 90) to
“Network” so that the drive uses the Reference from the
module. Also, verify that SP600 drive para meter 89 (Logic
Source Sel) is configured to recei ve the desired logic from
the module.

Step 3. If you enabled one or mor e Datali nks (option al), configu re

parameters in the drive to determine the source and
destination of dat a in the Data link(s). Also, e nsure that the
RS485 DF1 module is the only module us in g the enabled
Datalink(s).

Step 4. Reset the module. Refer to section 4.7.2, Resetting the

Module.

The module is ready to receive I/O from the master (i.e., scanner).
You must now configure the scanner to recognize and transmit I/O
to the module.

RS485 DF1 Communications Module

4.7 Setting a Fault Action

By default, when communications are disrupted (for example, a
cable is disconnected) or the scanner is idle, the drive responds by
faulting if it is using I/O from the network.

You can configure a different response to communication
disruptions using module parameter 10 (Comm Flt Action).

ATTENTION:Module parameter 10 (Comm Flt
Action) lets you det erm ine the ac ti on of the module

RS485 DF1 Communications Module

GLOSSARY

BCC (Block Check Character) - A technique for error detection in
data commun icati ons. A chara cter i s added to a trans miss ion b lock,
which is compared with a second BCC computer by the receiver to
determine if the transmission is error free.

controller - Also c al led p rogrammable logic c ontr oll er. A solid-state
control system that has a user-programmable memory for storage
of instructions to implement specific functions such as I/O control,
logic, timing, counting, report generation, communication,
arithmetic, and data file manipulation. A controller consists of a
central processor, input/output interface, and memory.
scanner.

CRC (Cyclic Redundancy Check) - A commonly used technique
for error detection in data communications. A polynomial algorithm
is performed on the data, and the resultant checksum is appended
at the end of the frame. The receiving device performs a similar
algorithm.

data rate - The speed at which data is transferred on the RS485
DF1 network. Each device on an RS485 DF1 network must be set
for the same dat a rate. You can set the RS485 DF1 module to 120 0,
2400, 4800, 9600, 19.2 K or 38.4 kbps.

Glossary

Datalink - A type of pointer used by some SP600 drives to transfer
data to and from the controller. Datalinks allow specified parameter
value(s) to be accessed or changed without using explicit
messages. When enabled, each Datalink consumes either four
bytes or eight bytes in both the input and output image table of the
controller. The drive determines the size of Datalinks.

DF1 - A Rockwell Automa tion Datalink la yer protocol that combines
features of subcategories D1 (data transparency) and F1 (two-way
simultaneous transmission with embedded responses) of ANSI
x3.28 specification.

DPI (Drive Peripheral Interface) - A peripheral communication
interface used by various Reliance Electric drives and power
products.

DPI peripheral - A device that provides an interface between DPI
and a network or user. Peripheral devices are also referred to as
“modules” and “adapters .” The RS485 DF 1 module and SP600 OIM
are examples of DPI peripherals.

Glossary-1

DPI product - A device that uses the DPI communications interface
to communicate with one or more peripheral devices. For example,
a motor drive such as a SP600 drive is a DPI product. In this
manual, a DPI product is also referred to as “product” or “host.”

fault action - Determines how the module and connected product
act when a communications fault (for example, a cable is
disconnected) occurs or when the scanner is switched out of run
mode. The former uses a communications fault action, and the
latter uses an idle fault action.

fault configuration - When communications are disrupted (for
example, a cable is di sconnected), the module and SP600 drive can
respond with a user-defined fault configuration. The user sets the
data that is sent to the drive in the fault configuration parameters
(parameters 15 (Flt Cfg Logic) through 24 (Flt Cfg D2 In)). When a
fault action para meter is set to use the faul t configura tion and a fault
occurs, the data from these parameters is sent as the Command
Logic, Reference, and/or Datalink(s).

flash update - The process of updating firmware in the module.
The module can be flash updated using the X-Modem protocol and
a RECOMM-232 serial converter.

hold last - When communications are disrupted (for example, a
cable is disconnected), the module and SP600 drive can respond
by holding last. Hold last results in the drive receiving the last data
received via the RS485 D F1 conne ction before the di sruptio n. If the
drive was running and using the reference from the module, it will
continue to run at the same reference.

Glossary-2

II/O data - I/O data, sometimes called “implicit messages” or “input/
output,” transmit time-critical data such as a Logic Command and
Reference. The terms “input” and “output” are defined from the
scanner’s point of view. Output is transmitted by the scanner and
consumed by the module. Input is transmitted by the module and
consumed by the scanner.

Logic Command/Logic Status - The Logic Command is used to
control the SP600 drive (for example, start, stop, direction). It
consists of on e 1 6-bit word of input to the mo dul e from the network.
The definitions of the bits in this word depend on the drive.

The Logic Status is used to monitor the SP600 drive (for example,
operating state, motor direction). It consists of one 16-bit word of
output from the module to the network. The definitions of the bits in
this word depend on the drive.

RS485 DF1 Communications Module

module - Devices such as drives, controllers, and computers
usually req uire a module to provide a co mmunication interface
between them and a network such as RS485 DF1. An module
reads data on the netwo rk and transmits it to the connected device.
It also reads data in the device and transmits it to the network.

The RS485 DF1 module connects SP600 drives to an RS485 DF1
network. Modules are sometimes also called “adapters,” “cards,”
“embedded communication options,” “gateways,” and “peripherals.”

node address - An RS485 DF1 network can have as many as 255
devices connected to it. Each device on the network must have a
unique node address from 0 to 254.

non-volatile storage (NVS) - NVS is the permanent memory of a
device. Devices s uch as the modu le and drive store p arameters and
other information in NVS so that they are not lost when the device
loses power. NVS is sometimes called “EEPROM.”

operator interface module (OIM) - A device that can be used to
configure and control a SP600 drive.

PCCC (Programmable Controller Communications Command) ­The protocol used by some controllers to comm unicate with de vices
on a network. Some software products (for example, VS Utilities)
also use PCCC to communicate.

ping - A message that is sent by a DPI product to its peripheral
devices. They use the ping to gather data about the product,
including whether it can receive messages and whether they can
log in for control.

Glossary

Reference/Feedback - Reference is used to send a referenc e (for
example, speed, frequency, torque) to the p roduct. It consis ts o f one
word of input to the module from the network. The size of the word
(either a 16-bit word or 32-bit word) is determined by the drive.

Feedback is used to monitor the speed of a product. It cons is t s of
one word of output from the module to the network. The size of the
word (either a 16-bit wo rd or 3 2-bi t wo rd) is de term in ed by th e d riv e.

scanner - A separate module (of a multi-module controller) or a
built-in component (of a single-module controller) that provides
communication with modules connected to a network.

See also

controller.
status indicators - LEDs that are used to report the status of the

module, network, and drive. They are on the module and can be
viewed on the front cover of the drive when the drive is powered.

Glossary-3

T yp e 0/ Type 1/Type 2 Control - When transmitting I/O, the module
can use diff erent types o f messag es for con trol. The Type 0, T ype 1,
Type 2 control events help Reliance Electric personnel identify the
type of message that a module is using.

transaction number (TNS) - A two-byte field in a DF1 message
packet that is used in combi nation with th e SRC (source no de of the
message) and CMD (command code) bytes to uniquely identify
every message packet. The TNS typically increments each time a
new DF1 messa ge is s ent. The reply me ssage w ill co ntain the same
TNS value.

VS Utilities software - A Windows-based software tool for
monitoring and co nfiguring Re liance Ele ctric produ cts an d module s.
VS Utilities can be used to configure the RS485 DF1 module and
SP600 drives.

zero data - When communications are disrupted (for example, a
cable is disconnec ted) , the mo dule an d drive can res pond wi th zero
data. Zero data results in the drive receiving zero as values for
command data. If the drive was running and using the reference
from the module, it will stay running but at zero reference.
