MSR128 series is a Windows-PC-based recorder software program, which connects
to economical I/O modules such as models RZUS, RZMS, R1M, R2M, R3 and
R5 for DC mV, mA, thermocouple, RTD/potentiometer inputs and discrete
I/Os. The MSR128 is fully featured enabling the logging, trending, acquisition
and analysis of application data. Combined with I/O modules, the MSR128
provides a low cost industrial grade data acquisition system.
A typical application for the PC recorder would be to monitor temperature,
pressure, flow and other process signals. However, in several cases, our
customers are using it for emergency supervision of their power facilities.
They had been using a DCS in the central control room. Their DCS had a
limitation because it would only show about 10 loops per screen, so they
had to switch between multiple pages when monitoring dozens of loops.

The MSR128-V4 is a full-featured software package based
on traditional chart recorders. It also has several advanced functions
not found in chart recorders. An overview feature is one of them. All
128 channels (8 pens x 16 groups) can be monitored in one view. Four alarm
set points per channel can be set for each channel. You can choose a color
for each alarm zones. By using the same color-coding for all pens, 128
channels of alarm monitoring can be easily checked in the Overview. The
Alarm History is recorded with a Time Stamp in the Alarm History view.

In the Alarm Setting dialog box, you can specify which
tags you want to be notified when an alarm trips, together with a message
that you can specify. The Alarm Information window appears on the screen
with a beep sound in an alarm condition, showing Time Stamp, Tag Name,
Pen Number and Message. This line continues to blink until the alarm is
acknowledged. The Alarm Information and Alarm History windows function
are indispensable for a data logger, enable personnel to be notified when
an alarm event occurs and to review alarm history records. Using a combination
of Overview and Alarm History, the PC recorder can be used for emergency
supervisory purpose. |
