Advise the Modbus emulator, I need to test connect from master to slave and get registers from slave using Modbus RTU protocol, connection via rs-232 interface.

  • plc-blog.com.ua/devemu_emulator_modbus maybe worth a try? - DimXenon
  • In general, on request there are a lot of links with descriptions: yandex.ru/search/?text=Modbus%20rs-232%20emulator - DimXenon
  • Yes, that I will not start to download - the antivirus blocks, the port does not open, so I ask for verified ones. - Andrey Sibirkin
  • I downloaded the Modbus Slave emulator, in theory I should simulate the connected com port, ok, I looked into the device manager there already com1 is busy, trying to create a connection com2, writes - "Port 2 not avaliable" and I think I can, instead of a Slave emulator Master download? - Andrey Sibirkin
  • Your system will “listen” to the controller-server, which is designated as slave. (Server - slave, client - (your application) - master. Strange at first glance, but this designation.) So you need an emulator - slave. - DimXenon
