Modbus Reader is a FREEWARE program. If you have already created a Modbus Constructor project for the device you designed, your clients will not have to purchase Modbus Constructor – it is enough to download a freeware Modbus Reader.
Modbus Reader can run several projects at once, i.e. query or simulate several devices using Ethernet or COM ports.
Data logging supported for multiple devices.
Modbus over TCP/IP, Modbus RTU and ASCII protocols are supported.
In addition to the requests specified in your project, you can modify any of your device's data elements by simply clicking on any associated data field, whether in Master (by sending an appropriate request) or Slave mode.
