The Allen-Bradley 2080-MEMBAK-RTC2 is a Micro800 memory backup module with 4 MB capacity. It allows compatible controllers to store backup copies of their application projects, supporting maintenance procedures and controlled recovery of PLC programs.
The integrated RTC provides one-second read resolution and specified accuracy of ±5 seconds per month at 25°C or ±9 seconds per month over the -20 to +65°C operating range. It supports PLC applications requiring date and time information without frequent manual clock recalibration.
The module supports controller project backup, restoration and cloning of compatible Micro800 application code. These capabilities can assist with deploying a validated application to another supported controller, subject to controller model, firmware, project and security compatibility.
Compared with the earlier 1 MB 2080-MEMBAK-RTC, the 2080-MEMBAK-RTC2 offers 4 MB memory and supports cloning or updating Micro870 application code. The module is also supported on appropriate Micro830 and Micro850 configurations but is not compatible with Micro820 controllers.
The clock includes battery-backed operation when controller power is unavailable. Rockwell Automation publishes 3.5 years of specified power-off battery life at 25 to 65°C and 2.5 years at 0°C, measured from the date of manufacture. Actual service life depends on elapsed storage time and controller power-off duration.
The plug-in installs directly into the leftmost compatible Micro800 controller slot. Project backup and restore operations can be managed through Connected Components Workbench or FactoryTalk Design Workbench. The module is not intended to increase runtime recipe or data-logging storage capacity.

What is the Allen-Bradley 2080-MEMBAK-RTC2?
It is a Rockwell Automation Micro800 plug-in module combining 4 MB memory for compatible PLC project backup and application code cloning with a high-accuracy real-time clock.
How much memory does the 2080-MEMBAK-RTC2 provide?
The module has 4 MB memory capacity intended for supported controller project backup, restore and application code cloning functions.
Does the module provide a real-time clock?
Yes. It includes a high-accuracy RTC that can provide date and time information to supported Micro800 controller applications.
What is the real-time clock accuracy?
Rockwell Automation specifies ±5 seconds per month at 25°C and ±9 seconds per month over the -20 to +65°C operating temperature range.
What is the RTC time resolution?
The documented READ_RTC() resolution is one second.
Can the 2080-MEMBAK-RTC2 back up a PLC program?
Yes. It supports backup copies of compatible Micro800 controller projects, with supported backup and restore workflows available through Rockwell Automation programming software.
Can the module be used to clone programs between PLC controllers?
Yes. Rockwell Automation documents application code cloning and updating functions. Before using a backup with another controller, verify hardware compatibility, firmware, project configuration and any relevant controller security settings.
Does the 2080-MEMBAK-RTC2 support Micro870 controllers?
Yes. Its 4 MB capacity is designed to support Micro870 application code backup and cloning, which is an important distinction from the earlier 1 MB 2080-MEMBAK-RTC.
Is the module compatible with Micro820 controllers?
No. Rockwell Automation explicitly states that the 2080-MEMBAK-RTC2 is not supported on Micro820 controllers.
Which Micro800 controllers are compatible?
The module is supported by appropriate Micro830, Micro850 and Micro870 configurations. Micro810 controllers do not have plug-in slots, while Micro820 controllers do not support this memory module.
Which controller slot must be used?
The 2080-MEMBAK-RTC2 must be installed in the leftmost plug-in slot. Unlike many other Micro800 plug-in modules, it cannot be installed in an arbitrary available plug-in position.
Does the real-time clock continue operating when controller power is off?
The module provides battery-backed RTC retention during controller power-off conditions, subject to the remaining battery capacity and applicable operating specifications.
How long does the RTC backup battery last?
Rockwell Automation specifies 3.5 years of power-off battery life from the manufacturing date at 25 to 65°C and 2.5 years at 0°C. Controller powered-on time is excluded from the stated power-off life, so actual calendar service life varies with usage and storage history.
Can the 4 MB memory be used for runtime data logging?
No. The manufacturer states that memory backup plug-ins cannot be used as additional runtime program or data storage for recipes and data logging. Their purpose is project backup, restoration and supported application code cloning.
What is the difference between 2080-MEMBAK-RTC and 2080-MEMBAK-RTC2?
The 2080-MEMBAK-RTC has 1 MB memory, while the 2080-MEMBAK-RTC2 provides 4 MB. The larger module supports Micro870 application code cloning and updating, and controller compatibility differs between the two catalog numbers.
Can the 2080-MEMBAK-RTC2 be removed or inserted with the controller powered on?
Rockwell Automation identifies the 2080-MEMBAK-RTC and 2080-MEMBAK-RTC2 as exceptions to the general Micro800 plug-in restriction on removal and insertion under power. However, any such operation must comply with the exact manufacturer procedure, controller conditions and electrical safety requirements. De-energized installation remains the preferred method when practical.
What software is used for project backup and restoration?
Connected Components Workbench and FactoryTalk Design Workbench provide supported project backup and restoration workflows for compatible controllers and module configurations.
Is the Allen-Bradley 2080-MEMBAK-RTC2 discontinued?
Rockwell Automation currently identifies the 2080-MEMBAK-RTC2 as an Active product. Confirm current lifecycle information when planning long-term support.
What should be checked before ordering?
Confirm the exact catalog number 2080-MEMBAK-RTC2, 4 MB memory capacity, high-accuracy RTC requirements, compatible Micro830, Micro850 or Micro870 controller, leftmost plug-in slot availability, controller firmware, supported backup and restoration software, battery age and remaining retention requirements. Do not select this module for Micro820 controllers or for additional runtime recipe and data-log storage.
