e-mail (up to 5 recipients) at the indicated hour every day, on a selected day of the week or
on a selected day of the month.
Alarms and control
Two alarm thresholds may be set for every channel. Binary outputs can be assigned to
alarm thresholds. Two modes are available for alarms: latched
(‘Alarm’ mode) and
non-latched
(‘Control’ mode). The binary output module (OUT6RL) contains 6 outputs
relays. The message about exceeding the alarm threshold and return to the normal value
can be sent automatically in the form of an e-mail (up to 5 recipients).
Math channels
Within the math channels, selected mathematical operations are available: addition,
subtraction, division, multiplication, raising to the 2, 3 or any power and square root. The
formula entered in the math channel can contain up to 200 characters.
Results recording
Process values, math channels and totalizers can be recorded into internal flash memory
with the capacity of 2 GB. Data are saved as text files and protected with encoded
checksum. Apart from the measured values, the recorder also saves events (power loss,
resetting, exceeded threshold values, etc.) and authorised operations.
Displaying the results
Measured and calculated results can be displayed on the 7
” colour LCD screen.
Depending on the configuration, results are displayed as graphs or digits (max. 11 signs
displayed for process values and max. 14 signs displayed for totalizers; after exceeding the
measuring range for process value or totalizer value, the ----- symbol will be displayed on
the screen and will be saved in the archive). The results can be also displayed collectively
as trend charts or tables (max. 11 signs for process values and totalizers values).
Measurement screens can be browsed sequentially or set to a selected channel.
Communication with a supervisory computer or a control system
The recorder enable data transmission to a supervisory computer or a control system by
means of:
a built-in RS-485 serial port; available Modbus RTU protocol,
Ethernet port; available Modbus TCP protocol.
