3 RS485 Port Configuration
TheRS485portcanbeusedtocommunicatewiththeDriveusingControl
Techniques' standard software communications packages such as UniSoft,
MentorSoft, CTFile and Systemwise. (Refer to the Help file in Unisoft, MentorSoft,
etc. for connection details.) The ANSI protocol is the standard protocol used by the
Control Techniques' software packages, but Modbus RTU and ASCII modes are
also supported as slave nodes only.
The RS485 port is configured by setting certain user parameters on the Unidrive or
Mentor II. These control individual features about the port. Any changes take effect
when the configuration parameters are stored and the UD70 or MD29 is reset.
The following parameters used to configure the RS485 port.
3.1 Node Address
Unidrive: #17.05 Mentor II: #14.01
Range: 11 to 99, excluding 00 to 09, 10, 20, 30, 40, etc for ANSI.
1 to 99 for Modbus RTU and Modbus ASCII
Default: 11
Every node on an ANSI or Modbus network MUST be assigned a unique serial
address. Changes to the node address will not take effect until the parameters
have been stored, and the UD70 or MD29 has been reset.
The serial address ensures that only the intended node responds to commands
issued by the network master controller. Each node should be assigned a unique
address BEFORE it is connected to the RS485 network.
