I am able to establish a TCP/IP connection (over port 502) to the embedded FreeModbus TCP server stack however I run into a perplexing crash when I try to process a simple get slave ID command to the server from a Windows Modbus client test app. The Modbus command appears well formed...

I'd like to program a TCP/IP Modbus driver to work with .NET so I can then develop an HMI. I want to do this from the ground up, but I'm not sure where to start. I've spent the day looking around for a Modbus driver that will work for me that is free, but one doesn't...
打开ModbusPal来模拟一个slave,添加一个coil(线圈) 模拟modbus slave之后,就可以开始攻击了,首先可以先爆破UNITID(站ID) Msf这个脚本是单线程,爆破起来很慢,也可以写一个python进行多线程爆破 可以看到UNITID是233的时候有返回值。确定UNID为233。 再使用auxiliary/scanner/scada/modbusclient模块对modbus进行攻击,这里...
