Allen-Bradley 1745-PT1 SLC 100/150 Handheld Programmer

The 1745-PT1 is a portable, handheld programming terminal designed for the Allen-Bradley SLC 100 and SLC 150 programmable logic controller families. Belonging to the Bulletin 1745 hardware series, this pocket programmer enables technicians and field engineers to enter, edit, test, and troubleshoot ladder logic programs directly on the factory floor without requiring a personal computer or software suite.

Program Editing and Diagnostic Capability

The 1745-PT1 provides full operational access to the controller's internal memory structures. Operators can enter ladder logic instructions, monitor bit statuses, edit preset values for timers and counters, and force input or output states during system commissioning. The integrated display and key layout are specifically structured around the instruction set of the SLC 100/150 series, facilitating rapid on-site modifications and diagnostic checks.

Interconnection and Field Operation

Designed for portable maintenance, the 1745-PT1 connects to the expansion or programming port of an SLC 100 or SLC 150 CPU unit using an optional 1745-C1 interface cable. Power for the terminal is drawn directly from the host controller through the interface connection, eliminating the need for an external power supply during field service operations.

Frequently Asked Questions

Q: Is the connecting cable included with the 1745-PT1 handheld programmer? A: No, the 1745-C1 interface cable required to connect the programmer to an SLC 100 or SLC 150 controller is not included with the 1745-PT1 unit and must be sourced separately.

Q: Does the 1745-PT1 require an external power supply or batteries? A: No, the 1745-PT1 draws its operating power directly from the connected SLC 100 or SLC 150 controller via the 1745-C1 programming cable.
