Handling SD Cards, ESM, and Batteries

SD Cards

Use only SD cards recommended by Rockwell Automation, such as catalog numbers 1784-SD1 or 1784-SD2, for optimal performance and reliability. Using non-recommended cards may lead to data corruption or loss, and may not withstand industrial environments.

Energy Storage Modules (ESM)

The ESM is essential for maintaining clock and memory retention when the controller is powered off. Ensure proper installation and handling to avoid damage.

Batteries

Batteries used in the 1756-L6x controllers need regular monitoring and replacement to ensure continued reliability. Different battery models have varying lifespans and storage requirements.
