Important notices regarding Weigh Scale Blender Communications - 3 Known Issues Below

6811 Controllers (Red Display) Send Settings / Recipe Download


Twelve software chips within the Maguire controller released between December 03, 2004 and July 12, 2005 (controller will display v=D1203L through v= E0712L) have a bug that affects downloading recipe from the G2 software to the blender. If a recipe is sent to the controller from G2 (or MLAN) during the time the blender is cycling, the new recipe components can be shifted up one component in the controller. If you are using G2 (or any other MLAN communication program) and twelve software controllers with a chip date code between December 03, 2004 and July 12, 2005 please contact Maguire Products for the latest chip version.

12-12 Controller - MLAN Set Remote Keypad, enabling Send Keystroke alters thumbwheel settings


This bug affects all 12-12 firmware versions going back to 2007. The bug involves the MLAN command "Set Remote Keypad" (ENABLE/DISABLE REMOTE KEYPAD in the MLAN Tester, G2 Software Control Blender Keypad) sent via MLAN over Serial or Ethernet. This would involve any program using the MLAN protocol to send and receive MLAN commands to the blenders including the G2 program, OPC, Modbus, Profibus or any other direct MLAN protocol product. The results of using the command Set Remote Keypad and enabling Send Keystroke (disabling controllers local keypad) on a controller that is using THUMBWHEELS can have a direct impact on the settings that the controller is currently running. Use of the thumbwheels includes both 4-Software thumbwheel auto-assignment as well as 12-Software manually assigned thumbwheels. The action of enabling the remote keypad causes the settings to change on all components using a thumbwheel. When the command DISABLE REMOTE KEYPAD is sent, the setting do not correctly adjust back although they do change again. Not until the controller is turned off then on again will the settings return to what is shown on the thumbwheels. If you use the remote keypad function and are experiencing this problem, please contact Maguire Products Inc for a software update.

High Totals generated from Controller


Two versions of 12-12 controller software were released with debug code enabled in the software that affected stored and reported component totals (Get Totals command). The two versions of software were:

L0202A /N
L0412A /N

The debug code would cause the controller's component totals to increment totals in very large amounts with each cycle. If a customer using MLAN communications (G2, OPC, Modbus, MLAN, Modbus, Profibus, Direct MLAN) experiences this problem, it would very evident that totals were incorrect. Software before as well as after these versions increments component totals correctly. If you have these versions and experiences this totals problem, please contact Maguire Products Inc. for a software update.

Hardware and Operating System Requirements

Hardware and Operating System Requirements for the installation of the G2 Server and/or the G2 Client Software
Computer System
IBM-PC or Compatible (Pentium III 600 or faster). We recommend that the G2 Server computer be dedicated to the purpose of collecting data for G2. Constant COM port communication between the G2 Server and the Maguire Weigh Scale Blenders may cause a noticeable lag in the processor when using the G2 Server computer for additional functions while the G2 Server is collecting data. Also note that if you are using Ethernet for blender communications to 25 or more blenders, demand on the computer system may require a system faster than stated above. In the case of Ethernet connected blenders totaling 25 or more, we recommend a minimum system of a Pentium III 1 GHz with 512 MB of RAM.
Operating System Requirements
G2 Server - Windows based platforms. Supported Windows Operating Systems: NT/2000/XP/VISTA/7/8
G2 Clients - Windows based platforms (95/98/ME/NT/2000/XP/VISTA)/7/8
(Windows 95/98/ME not recommended for G2 Server)
