FactoryTalk Logix Echo works within the system requirements of all Rockwell Automation® software products.

FactoryTalk Logix Echo has these minimum hardware requirements:

• 2.2-GHz Intel® Core i3 or faster processor:

• At least one logical core for the operating system
• At least two logical cores for the base FactoryTalk Logix Echo application
• At least one logical core per emulated controller instance; for best performance, two logical cores per emulated controller instance
• Additional logical cores dependent on additional software installed on the same workstation, server, or virtual machine

Tip: Downloading projects simultaneously to many controllers while the system is under heavy load can cause errors. To improve simultaneous download performance, reduce the number of controllers or downloads, or add additional logical cores to the system.

• 8 GB of available memory:

• 2 GB for software applications
• 256 MB for each started emulated controller instance (up to 1 GB)

• 4 GB of available storage space
• 1-GB network adapter

Tip: For best performance when using FactoryTalk Logix Echo in a virtual machine, take advantage of Intel® Virtualization Technologies.

FactoryTalk Logix Echo requires the following software on the host computer:

• Operating system

• Windows® 10 Professional and Enterprise
• Windows 10 Enterprise 2021 LTSC (v21H2)
• Windows 11 Professional and Enterprise
• Windows Server 2022 Standard and Datacenter Editions
• Windows Server 2019 Standard and Datacenter Editions

When you install FactoryTalk Logix Echo, these components are installed:

• FactoryTalk Logix Echo Service version 2.01.00
• Firmware packages
• Dashboard version 2.01.00

This component is installed if you select it on the installer:

• SDK version 2.01.00

This software is also available to install based on what is installed on the host computer:

• FactoryTalk® Services Platform v6.31.00
• FactoryTalk® Activation v5.00.11
• FactoryTalk® Diagnostics
• FactoryTalk® Alarms and Events v6.31.00
• FactoryTalk® Linx v6.31.00

FactoryTalk® Logix Echo™ version 2.01.00 introduces these features:

• Create, modify, and delete GuardLogix 5580 emulated controllers as well as ControlLogix 5580 emulated controllers.
• Add multiple chassis to emulate multi-chassis environments.
• The FactoryTalk Logix Echo application programming interface (API)  supports 32-bit and 64-bit applications.

Emulated controllers sometimes shut down when program contains a motion axis (1833982)

When the program for an emulated controller contains a motion axis, the emulated controller might shut down suddenly during startup.

To work around this issue, try starting the emulated controller again.

This anomaly first identified in the FactoryTalk Logix Echo application, version 2.01.00.

IP address and network mask are not restored from the SD card (1708087)

When you save an emulated controller configuration to the emulated controller SD card, change the IP address and network mask, and then restore the configuration from the SD card, the IP address and network mask are not restored to the original configuration.

To work around this issue, use a snapshot to restore a configuration.

This anomaly first identified in the FactoryTalk Logix Echo application, version 2.01.00.

Controllers stop responding during snapshot creation (1767371)

One or more controllers might stop responding during Snapshot creation. The message Controller is not responding appears on the Device Status panel in the Dashboard for those controllers.

To work around this issue, turn the controller off and then on again, re-download the project, and attempt snapshot creation again.

This issue first identified in FactoryTalk Logix Echo version 2.01.

Invalid IP address blocks ability to change properties, turn controller off, or modify SD Card (1894909)

When you create an emulated controller using an ACD file or by restoring or importing a snapshot, and the IP address for the emulated controller is not valid, you cannot apply changes to some controller properties, and you cannot turn the controller off or modify the SD Card. The symptom of this anomaly is that, after you change a controller property on the controller with an invalid IP Address, the Apply button is disabled.

This error appears when you attempt to turn the controller off, attach or detach the SD card from the controller property screen, or toggle the controller on or off from the device status panel:

Modify controller failed. An error occurred when communicating with the FactoryTalk Logix Echo service. If this error occurs often, contact Rockwell Automation technical support.

However, there is no error to indicate that the IP address is not valid.

To work around this issue, enter a valid IP address for the emulated controller.

This anomaly first identified in FactoryTalk Logix Echo v1.00.

Delayed changes fault sometimes occurs for produced and consumed tags (1076648, 1172801)

When the Requested Packet Interval (RPI) is set to 200 ms or less for produced and consumed tags, a fault sometimes occurs that indicates a data change delay.

There is no workaround for this issue.

This anomaly first identified in the FactoryTalk Logix Echo application, version 1.00.00.

Trends display steps instead of a linear line (1093987)

Trends show steps instead of linear line while executing quantums larger than 10ms. Furthermore, some trends use physical time instead of virtual time.

This anomaly first identified in the FactoryTalk Logix Echo application, version 1.00.00.

These are the functional changes for FactoryTalk® Logix Echo™ version 2.01.00.

• Add multiple chassis to emulate multi-chassis environments.
• You can start a project download to additional controllers before the ongoing download is complete. Multiple downloads are logged into the same console log tab.
• The Firmware Packages pane lists the installed firmware packages. To install additional firmware, download it from the Rockwell Automation Product Compatibility and Download Center (PCDC) and install it using the Microsoft Windows installer.
• The Restore snapshot dialog now offers four options when you restore a snapshot:

• Restore only. This option restores the snapshot using only the chassis and controllers in the current configuration.
• Create only. This option adds new chassis and controllers without adjusting the current configuration.
• Restore and create. This option adds new chassis and controllers if necessary. The current configuration might be overwritten.
• Delete all and create. This option deletes the current configuration and creates the controllers and chassis in the snapshot.
