MODBUS TCP Registers

This appendix lists the CGR 2010 ESM-specific read-only registers. MODBUS clients use them to communicate with a MODBUS server (i.e., the switch module). There are no writable registers. For configuration information about MODBUS TCP, see Chapter16, “MODBUS TCP Configuration”

System Information Registers

Memory address spaces 0x0800 through 0x0FFF are system information registers. Clients use the 0x03 Read Multiple Registers MODBUS function code. The system-information register mapping is as follows:

Port Information Registers

The port information registers are documented as follows:

  • Table C-2 below provides the port information register mapping for the CGR 2010 ESM SFP model (GRWIC-D-ES-6S)
  • Table C-3 provides the port information register mapping for the switch’s Copper model (GRWIC-D-ES-2S-8PC)
  • Table C-4 describes how to interpret the port state values for the switch’s SFP model
  • Table C-5 describes how to interpret the port state values for the switch’s Copper model
  • Table C-6 describes the interface-to-LPN mapping for the switch’s SFP model
  • Table C-7 describes the interface-to-LPN mapping for the switch’s Copper model

Port Information Register Mapping for SFP Model (GRWIC-D-ES-6S)

This section provides the port information register mapping for the CGR 2010 ESM SFP model (GRWIC-D-ES-6S).

Memory address spaces 0x1000 through 0x2FFF are interface registers. Clients use the 0x03 Read Multiple Registers MODBUS function code to access the registers.
