GM4-M032

Description

32k-step memory cassette for the GLOFA GM4 PLC family, used to expand program capacity beyond built-in CPU limits. LS Electric

The Polar Energy Assessment:

The GM4-M032 is a removable flash memory module that installs directly into compatible GM4 CPU units (e.g., GM4-CPUA/C). It provides additional non-volatile storage for larger programs, data logging, or backups, supporting up to 32k steps of ladder logic or function blocks. Ideal for applications requiring program portability or extended memory without upgrading the CPU. Follows GM4 OEM topology for seamless integration.

Pros

• Boosts program size affordably without CPU replacement.
• Non-volatile flash retains data during power loss; easy insert/remove for backups.
• Supports program upload/download via XG5000 software, enhancing flexibility.

Limitations

• Limited to 32k steps; larger applications may need GM4-CPUC or higher.
• Requires compatible CPU slot; not usable in base units without CPU.

Typical use cases

• Expanding program memory in mid-size machines, field program backups for maintenance, OEM builds with variable logic sizes, retrofits to avoid full CPU swaps.
