MODBUS ASCII/RTU master and slave simulation Description

MODBUS ASCII/RTU master and slave simulation is a plugin for Advanced Serial Port Monitor, capable of working as a MODBUS master or slave for accessing data contained in on a MODBUS device that is properly connected to the computer through a serial port. It may be used in the diagnostics of slave responses to MODBUS queries, being able to send custom command strings and allowing users to observe the outcome. For those unfamiliar with the term, MODBUS is a communication protocol that is widely used with programmable logic controllers, suited for industrial applications and electronics. Its main advantage is, besides easy deployment and maintenance, the fact that it doesn’t put significant restrictions on vendors, thus enriching the plethora of possibilities in what development is concerned. MODBUS ASCII/RTU master and slave simulation works in conjunction with Advanced Serial Port monitor, which is designed for monitoring the data from COM ports. Through it, the plugin can access resources from one or more MODBUS devices, being able to gather and output the response to various command strings for testing purposes. It features support for standard MODBUS messages, namely 01-06, 7, 8, 11, 12, 15, 16, 17 and 22 and uses standard Win32 drivers in order to communicate with COM ports, providing users with full control over the operating behavior of the serial connection. The plugin’s functionality can be explored from an individual window, where parameters such as Device ID, function, address and length may be customized. After you press the ‘Send Request’ button, the response starts to become available, allowing you to analyze the data in several formats. All in all, MODBUS ASCII/RTU master and slave simulation could be a great asset for users who are dealing with MODBUS devices often, allowing them to diagnose and troubleshoot connection and functional issues.
