    REV. 5 Liebert Monitoring Group –Development Modbus Communications Connectivity to OpenComms-485 using Modbus This design specification describes the Modbus communications protocol as supported by the OC-485 interface card. It includes information on how to pass information to and from the OC-485 card via Modbus. It is also intended to help facilitate answering questions regarding supported types, frame format, function code support etc.
  • Page 5 Modbus Packet Format Each Modbus packet consists of the following fields: • Device Address • Function Code • Data Field(s) • Error Check Field The address field immediately follows the beginning of the frame and consists of 8-bits (RTU). This bit indicates the user assigned address of the slave device that is to receive the message sent by the attached master device.
  • Page 6 Write multiple Registers The data field varies in length depending on whether the message is a request or a response to a packet. This field typically contains information required by the slave device to perform the command specified or to pass back data to the master device.
