Sherwood 1.09, published by the sz development, is a lightweight, single-version tool designed for engineers and technicians who need to inspect and log data held in Modbus-capable industrial devices. By speaking both Modbus RTU (serial) and Modbus TCP/IP (Ethernet), the program can poll registers from PLCs, drives, meters, and other slaves without forcing users to switch between separate utilities. The resulting live table can be saved, exported, or used as the nucleus of a simple SCADA layer: alarms, trends, and supervisory screens can be built directly around the polled data, eliminating the cost and complexity of full-scale supervisory packages for small pilot lines, test benches, or remote monitoring cabins. Typical deployments include verifying sensor scaling after a field replacement, commissioning solar inverters before hand-off, or collecting energy counts from a chain of Modbus meters spread across a campus. Because the interface stays close to the raw register map, integrators can also confirm that slave documentation matches the actual memory layout before committing to larger HMI projects. Sherwood therefore sits in the “Automation / SCADA” software category, yet remains lean enough to run on rugged laptops carried into plant areas where enterprise licensing and online activation are impractical. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
