PRODUCT PROFILE
The 1769-SM2 module provides a direct 1769
platform connection for PowerFlex
®
4, 40, and
400 AC drives, other DSI-based host devices, and
Modbus RTU-based host devices such as PowerFlex
70, 700, and 700S AC drives equipped with 20-
COMM-H adapters. The 1769-SM2 can be used
with MicroLogix
™
1500 and CompactLogix
™
controllers, and remote 1769-based nodes such
as the 1769-ADN DeviceNet
™
adapter to control,
configure, and collect data.
PRODUCT HIGHLIGHTS
1769 Platform Connectivity – The module
can be used in 1769-based systems, such as:
• MicroLogix 1500 controllers
• CompactLogix controllers
• Remote 1769-based node adapters
(1769-ADN DeviceNet, etc.)
Three DSI/Modbus RTU Channels – 3 channels
are provided and can be configured for:
• Single-Drive Mode – One PowerFlex 4, 40 or
400 AC drive per channel (3 drives total)
• Multi-Drive Mode – Up to five PowerFlex 4, 40
or 400 AC drives per channel (15 drives total)
• Modbus RTU Master – Connect Modbus RTU
Slave devices, including 3rd Party devices and
PowerFlex 70, 700, and 700S AC drives
equipped with 20-COMM-H adapters
I/O Messaging – I/O messaging is used to
transfer time-critical data, such as data that
controls the drive. The following data can be
sent and received by the adapter:
• Logic Status/Speed Feedback
• Logic Command/Speed Reference
Explicit Messaging – Explicit messaging involves
non time-critical information that is typically
triggered by the application (ladder program in
a controller, etc.). The adapter supports the
reading/writing of parameters, etc. in the drive
and to any connected DSI peripheral(s).
Multiple Configuration Tool Options – A
number of configuration tools can be used to
configure the adapter and the connected drive.
When the 1769-SM2 is set to “Parameter” mode,
tools like the PowerFlex DSI HIM, or drive-
configuration software such as DriveExplorer
™
or
DriveExecutive
™
can be used. When set to
“Controller” mode, software tools such as
RSLogix 500
™
, RSLogix 5000
™
or RSNetWorx for
DeviceNet
™
can be used.
User Configurable Fault Responses – Selects the action that the adapter and drive will
take for the following two conditions:
• Idle Fault Action – the scanner is idle (controller in program mode)
• Comm Fault Action – network communications have become disrupted
Available actions include:
• Fault – the drive is faulted and stopped
• Stop – the drive is stopped using the current deceleration rate and is not faulted
• Zero Data – the adapter zeros the I/O data transmitted to the drive
• Hold Last – the adapter continues sending the I/O data prior to the fault and the
drive continues in its present state
• Send Fault Configuration – the user specifies the Logic Command, Speed Reference,
and Datalink data that is sent to the drive, allowing complete flexibility in configuring
a fault action
Diagnostics – Built-in diagnostics allow drive-side troubleshooting of the network
connection using a PowerFlex DSI HIM, DriveExplorer or DriveExecutive. View actual
Logic Status/Speed Feedback and Logic Command/Speed Reference data being
transmitted to and from the controller.
Flash Upgradeable – The adapter can be flash updated in the field using DriveExplorer,
DriveExecutive or ControlFLASH to take full advantage of new firmware features as they
become available.
