Description
The Modbus RTU driver allows the FieldServer to transfer data to and from devices over either RS-232 or RS-485 using Modbus RTU protocol. The FieldServer is capable of being used as a port expander.
The FieldServer can emulate either a Server or Client. The FieldServer is capable of supporting devices that use two Modbus Registers to transfer IEEE floating point format.
Fieldserver Mode | Nodes | Comments |
Client | 1 | Only 1 client node allowed on Multidrop systems |
