  • Page 5: Scope

    1.0 SCOPE This document is a User Interface Specification for the Walchem Modbus/TCP product feature for W600 and W900 Controllers. It contains mapping of the various dynamic variables to their Modbus/TCP address locations. This document supports the Modbus/TCP feature on controller software versions 3.01 and higher.

  • Page 6: Modbus Settings

    Modbus Settings Settings relating to the Modbus/TCP feature can be configured in the Remote Communication Configuration Menu. The ‘Verbose Logging’ setting is used to generate an Event log entry for every Modbus message into and out of the controller. The information may be used in conjunction with an HMI log when troubleshooting communications during commissioning.

  • Page 12: Tcp/Ip Interface

    TCP/IP Interface The Modbus/TCP interface is attached to the TCP/IP stack that is implemented within the Walchem controller. When the Modbus feature is Enabled, the controller will listen to all communications that come in on the Modbus/TCP registered port 502. This port can be changed in the Remote Communications Menu.

  • Page 13: 16-Bit Word (Bitfield)

    4.4.2.2 16-Bit Word (Bitfield) Holding Registers and Input Registers can be used for Alarm Bitfields. An 8-Bit Alarm bitfield is packed into the least significant byte of a 16-bit register. This is offered as a single-register alternative to accessing alarm states individually. Bitfields can be decoded in section 5.5 Alarm Bitfields.

  • Page 14: 32-Bit Inverse Data Format (Integer Or Float)

    Input Register (FC4), the address indices 2 and 3 must be requested together: Addresses 30039 and 30040. To read the ‘Low Alarm’ status for Sensor 2-1 in a W600 Controller as a Coil (FC1), the Sensor Input Address Map indicates the starting address is x0865.

  • Page 18: Alternate Address Maps

    5.2.3 Alternate Address Maps The Alternate Address Maps provide a more efficient way to access similar data from different objects. Using these address tables, the same field type is accessible using consecutive addresses. For example, the primary values for all sensors installed in the controller can be accessed in a single Modbus FC4 request/response cycle starting at address 39217.
