Honeywell’s Enhanced Logic Manager Module (ELMM) provides an innovative modernization solution for legacy TDC 3000 and TotalPlant™ Solution systems with Logic Manager (LM). The ELMM enables incremental migration to the modern and long term supportable Enhanced Universal Control Network (EUCN) platform.​

Honeywell has developed an innovative way to migrate the Logic Manager to the latest Enhanced Universal Control Network (EUCN) technology. The Enhanced Logic Manager Module (ELMM) is designed to migrate the Logic Manager Module (LMM) on the Universal Control Network (UCN) to a modern and long term supportable platform. Users can implement the new software emulated ELMM to host LMM functions on a ControlEdge PLC and the same PLC can also be used for execution of control application converted from IPC 620 Processor eliminating the need for separate hardware for the interface to EUCN and to provide control execution. ControlEdge PLC is fully compliant to IEC 61131-3 supporting all five programming languages: Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), Instruction List (IL) and Sequential Function Chart (SFC).

Honeywell’s ELMM is a software emulation of the LMM module and is hosted on ControlEdge PLC. The same ControlEdge PLC also serves to replace the LM’s IPC 620 controller, and the migration project uses a proprietary tool to migrate the LM database and ladder programs to ControlEdge compatible application.


The ELMM supports all EUCN characteristics while offering tight integration with the Enhanced High Performance Process Manager (EHPM) and other EUCN nodes. It retains intellectual property in legacy assets by conserving applications running on the TPN. The ELMM also retains point processing and accepts checkpoints from the legacy module. All peer-to-peer configurations remain unchanged. The ELMM solution is specifically designed to support critical performance indices (i.e., latency, point processing and parameter access limits) while integrating system alarm and diagnostic functions. ​

By implementing the ELMM, Honeywell customers can:

•  Lower operational expenses, by implementing distributed I/O and control using ControlEdge PLC and its 900 Platform I/O modules. 

• Simplify project engineering through optional use of Universal I/O for ease of modification post- commissioning

• Realize greater operational integration for easier plant operation and maintenance

• Protect intellectual property and reduce re-engineering costs

• Minimize shutdown time with no changes to existing applications
