Weigh Scale Blender Communications
The Maguire Weigh Scale Blenders are capable of two-way communications for enhanced control and data collection. The Maguire Weigh Scale Blender's Controller itself uses Maguire's MLAN Protocol to send and receive data through commands within the protocol. All Maguire Controllers use RS-232 (MLAN) or Ethernet for communications. Our 12-12 Controller has Ethernet onboard while older Maguire Controllers can utilize an Ethernet to Serial Converter. See the Weigh Scale Blender's manual
for communication port details. Several options are available for methods of communication, all of which use the MLAN Protocol.
Gravimetric Gateway™ Server (G2 Server)
The Gravimetric Gateway Server also referred to as the G2 Server, is the name we give to the server software written exclusively for the MAGUIRE Weigh Scale Blenders. The G2 Server enables you to communicate directly from the server with one or more WSB controllers or connect remotely from anywhere over a TCP/IP network using the Gravimetric Gateway™ Client Software. The Gravimetric Gateway™ Server provides two-way communication between the server and the MLAN network of blenders through downloading and constant retrieval of information from WSB controllers. The Gravimetric Gateway™ software was designed to work as a stand-alone application to provide enhanced reports and control. The Gravimetric Gateway™ software has the ability to use MySQL for it's databases.
The full version of the Gravimetric Gateway™ Server/Client Software is available for download here on the web site. This full version software is limited to running as a demo package and/or as G2 Lite which offers support for a single Maguire Blender. In this free download, extrusion control is not available. To unlock the full potential of this G2 software package , including extrusion control, a security key is required and is available from Maguire Products. Download the latest full version
, or call Maguire Products for more information about G2. Download the G2 Software
OPC - Object Linking and Embedding (OLE) for Process Control
OPC is a worldwide standard of application interface in industrial automation software and the enterprise systems that support industry. Maguire Products has worked closely with the following OPC Server developers to provide OPC profiles to work directly with our Weigh Scale Blenders. If you are interested in using OPC, please contact the following companies to discuss Maguire Weigh Scale Blender communications. All transactions and support for OPC are through the OPC Developer company.
Modbus over TCP/IP (12-12 Controllers only)
The Maguire 12-12 Controller is capable of Modbus communications over TCP/IP. Modbus for the Maguire 12-12 controller uses the MLAN Protocol command set as outlined in the Excel spreadsheet below.

Direct MLAN Protocol
The MLAN Protocol (Maguire Local Area Network) is a protocol consisting of commands that allows two-way communications to the Maguire Weigh Scale Blenders. All Maguire Weigh Scale Blenders dated back to 1992 contain the essential MLAN commands for basic control and data collection while newer Maguire controllers contain additional commands for enhanced control and data collection. The MLAN Protocol was initially intended to provide information for individuals who are writing software for Programmable Logic Controllers (PLCs) and needed to communicate with the Maguire Weigh Scale Blender. This protocol is the method used by our G2 Software as well as the OPC profiles written for the OPC servers listed above. The Protocol is available for free and is explained in detail in our MLAN Protocol Manual
. Customers who wish to write their own software to communicate directly with the Maguire Weigh Scale Blenders will need the MLAN Protocol Manual
. For a complete understanding of the operation of the Weigh Scale Blender (WSB), it is recommended that you have the four and/or twelve component controller manual(s) available as a reference.
