Siemens 6ES5605-0UB11 – Hand-Held Programmer for SIMATIC S5 On-Site Changes

The Siemens 6ES5605-0UB11 enables small program modifications without a full programming unit. This hand-held device measures 210 mm in length and 85 mm in width. It has a depth of 35 mm, so it fits in toolboxes easily. The unit weighs 0.35 kg, making field use comfortable and portable.

Display and Keypad Specifications

This hand-held programmer features a 2-line by 16-character LCD for program viewing. The Siemens 6ES5605-0UB11 includes a 22-key membrane keypad for data entry. It provides dedicated keys for timer, counter, and bit operation commands. The display shows rung numbers, instruction codes, and parameter values clearly. A contrast adjustment wheel optimizes viewing in various lighting conditions.

Programming Functions and Memory Capacity

You can edit timers, counters, and bit logic values with this hand-held device. The Siemens 6ES5605-0UB11 monitors up to 32 program elements in a single session. It stores 8 kB of internal memory for offline program preparation. The unit supports force commands for testing input and output circuits. It also displays CPU status, scan time, and diagnostic buffer contents.

Communication Interface and Connection Details

You will find one 9-pin D-sub connector on the bottom of this programmer. The Siemens 6ES5605-0UB11 connects directly to the S5 CPU programming port. A 2-meter cable with 15-pin connector provides the physical link. The unit draws power directly from the connected S5 CPU module. It requires no external battery or power supply for operation.

Environmental Tolerance and Physical Design

The Siemens 6ES5605-0UB11 operates reliably from 0°C to 50°C ambient temperature. It tolerates humidity levels up to 85 percent without any condensation issues. The unit includes a rubber boot for impact protection during field use. A built-in belt clip allows hands-free carrying between control cabinets. The membrane keypad resists dust and light liquid spills effectively.

Below is a complete summary of its technical specifications.

The Siemens 6ES5605-0UB11 replaces older hand-held programmers in S5-115U systems. You do not need any additional software or computer for basic edits. This device also supports program transfer between multiple S5 CPUs. Consequently, it provides quick on-site troubleshooting and small logic changes.
