Allen-Bradley 1745-PT1 Handheld Programmer

The Allen-Bradley 1745-PT1 Handheld Programmer is a compact pocket programming terminal designed for Rockwell’s SLC-100 and SLC-150 PLCs, enabling on‑site programming, editing, monitoring, and troubleshooting of ladder logic and controller configurations in real time. It connects to an SLC‑100/150 processor via 1747‑C10 communications, allowing direct upload, modification, and verification of the user’s program without requiring a desktop PC-based development environment. As the dedicated pocket programmer for the Bulletin 1745 family, the 1745-PT1 is commonly used by maintenance technicians and systems integrators to load programs, diagnose faults, and verify I/O mappings and overall system behavior directly at the controller. This tool is associated with legacy SLC systems and remains a practical option for sustaining and updating older installations that rely on SLC‑100/150 controllers.
