PME (versions 6.0 to 9.5) is a Windows-based IDE that can program Series 90-30 PLCs. It supports all the same instruction sets and offers drag-and-drop ladder, online edits, and modern debugging.
A small number of online retailers and industrial surplus sellers continue to offer the software on physical media. These listings are for the complete, legal version of the software, typically on a two-CD package that includes the installation discs and a complement of reference manuals in PDF format. This can be a viable, legitimate option for those who require a physical backup or prefer a more formal acquisition method.

Ensure your USB-to-Serial adapter is mapped correctly to COM1 within the VM settings.
To run the Logicmaster 90-30 V9.05 software on a modern Windows 10/11 computer, follow these deployment steps:
He launched the software. For a second, the screen resolution shifted, the modern high-def display struggling to accommodate the archaic interface. Then, the familiar gray and blue interface of Logicmaster materialized. It was beautiful in its ugliness. Rows of ladder logic symbols, sharp and precise. If you’d like, I can: PME (versions 6
: Supported the creation, editing, and monitoring of ladder logic programs for the 90-30 and 90-20 series.
It provides ladder logic displays, program annotation, and real-time on-line diagnostics for Series 90-30 CPUs. Downloading & Installation
If your company originally purchased Logicmaster 90-30 but lost the floppy disks, you may have a legal right to obtain a backup copy from a colleague or an authorized distributor. Emerson’s license agreement historically allowed for one archival copy. In practice, many automation teams share a site license across a plant. These listings are for the complete, legal version
: A functional demo version (IC641SWP703) exists, but it limits program size to 750 bytes. Community sites like MrPLC.com occasionally host legacy files for troubleshooting purposes. System Compatibility
If the target PLC has a modern CPU (e.g., version 8.3 or later, or a CPU351/364), it is strongly advisable to use PAC Machine Edition. It eliminates the need for legacy operating systems and complex serial setup, as it communicates natively over Ethernet on supported models.
When looking for a reliable copy of the , engineers typically rely on three pathways: Pemmican Wars
GE’s automation division is now part of Emerson. Users with existing support contracts can often access legacy software archives through the Emerson Support Portal. This is the only way to ensure you are receiving an authentic, virus-free copy of the installation media. 2. Industrial Automation Archives
is more than just software—it is a bridge to millions of hours of proven, reliable industrial logic. While Emerson has moved on to Proficy and newer PLC families like the RX3i, and while modern plants are adopting IIoT and edge computing, the Series 90-30 continues to run in countless facilities. As long as these PLCs run, there will be a need for Logicmaster.
