  • Page 10: Modbus/Tcp Interface

    1.2 Modbus/TCP Interface Introduction HC900 controllers support the Modbus/TCP (also called Modbus TCP/IP or Modbus Ethernet) protocol for communications with third party HMI and SCADA software via a direct Ethernet TCP/IP connection. The controller’s Ethernet 10/100Base-T Host port is used for the Modbus/TCP connection. Ethernet TCP allows multiple concurrent connections to hosts for data interchange.
  • Page 11 HC900 Ethernet Communications Setup See the HC900 Process Control (HC) Designer Users Guide, Doc. # 51-52-25-110 or respective HC Designer Help Files for setting up the following network parameters: IP Address, Subnet Mask (optional), Default Gateway IP Address (optional) Be sure the PC, HMI panel, or other Host device has a Network Interface Card (NIC) with an IP address (fixed or DHCP served) that allows access to controllers on the same or other subnet.

    “Big Endian” is used with SpecView32 or Honeywell’s PlantScape/Experion/EBI software and follows the “Honeywell” default format of other control and recording products. It should be noted that most PC software packages offer a register (word) swap selection in their driver package anyway, so there should never be an incompatibility.

    Data that is 32 bits requires 2 sequential registers (4 bytes) to transfer its data. Data of this type includes IEEE 32-bit floating point, 32-bit signed integer and 32-bit unsigned integer. The stuffing order of the bytes into the two registers differs among Modbus/TCP hosts. To provide compatibility, the double register format for the HC900 controller is configurable.
