Ametek 3050 Series User Manual

A-2 | 3050-SLR Moisture Analyzer
The SerialMode parameter is set to 1 by default.
The SerialMode parameter change will not disturb the present serial communication link.
Power should be recycled or a reset command should be issued to activate the change in the
serial mode setting.
It is strongly recommended to conigure and to test 3050 analyzer in AMETEK ASCII mode
using user-friendly 3050 Conigurator software. The MODBUS RTU protocol mode should be
used for monitoring purposes.
When designing a Modbus RS485 multi-drop communication system with the Model 3050
analyzer, the system designer should consider the following:
• Analyzer primary output is moisture concentration and analyzer status codes.
The update rate of the moisture concentration is one time per minute or less.
Polling of these registers more frequently than once a second is not recommend-
ed.
• The maximum polling rate of a Modbus multi-drop system is determined by a
number of factors including the number of devices on the system, the number of
registers being polled from each device, the baud rate in half-duplex operation.
Calculations, and possibly experimentation, are needed to attain optimal system
operation.
