MODBUS TEST
The Modbus Test Program (WinMB) enables
you to test the operation of the serial port com-
munications, and determine Modbus register
and log contents. Use this program as an aid to
software debugging or for special installations.
Via WinMB, you can troubleshoot with any
device including the GC Controller, an
ultrasonic meter, or a flow computer.
Traditionally, Modbus registers are polled by
using a data collection system (DCS). To
facilitate installation and debugging, the
WinMB program emulates a DCS.
This section provides detailed instructions for
using the WinMB program. Use this program
only if you are familiar with Modbus
communication protocol and the operation of
the MON2000 software.
10.1 STARTING WINMB
To start WinMB from MON2000, pull down the
File menu and click the Modbus Test option.
FUNCTION NOT REQIURED FOR NORMAL GC OPERATION
The Modbus test is reserved for advanced functions
The Modbus Test function is not required for normal GC
operation. Skip this section unless you are developing
software, engaging in a software debugging process, or
designing a custom installation that directly accesses the
GC Controller Modbus registers.
