SCADAmatic has introduced SimServe, a professionally developed Modbus Slave Simulator tool for any software developer or systems integrator working with the Modbus protocol. SimServe can simulate an unlimited number of Modbus devices using Modbus RTU, Modbus ASCII and Modbus TCP/IP. When an engineer is developing a system that communicates to an external device using Modbus, but the device isn’t available, this simulator tool allows work to continue and development to be verified.
Several features make development tasks easier for engineers. With SimServe the engineer can create simulated devices in a network tree to realistically represent a production network. SimServe allows each simulated device to be assigned a unique IP address or serial COM Port, and it can even simulate protocol converters like a Modbus TCP to RTU gateway. SimServe also allows the creation of tags linked to Modbus registers with configurable data types. This lets the user easily set Modbus register values in human readable formats for data types that span multiple registers, like 32 bit integers, 32 bit floats and 64 bit floats.
Additionally, the user may configure the bit/byte/word order of each device to ensure it matches the production unit, which will eliminate the guess work of “byte swapping” at the time of deployment.
SimServe is a software-as-a-service (SaaS) tool that runs in the background whenever the computer is powered on. This makes it easy to install SimServe on a separate computer (physical or virtual) and to include it on a development platform. The web-based interface makes the tool easily accessible by multiple engineers involved in development. The software is compatible on Windows 10 and higher operating systems.
