Comet MS55D 16 Channel Data Acquisition Monitoring System with Display
- Measure and process 1 to 16 input variables
- Each of the 16 channels offers the virtual channel (countable)
- Acquire autonomous recording of measured values
- On-line monitoring of measured values and states
The complete solution for monitoring of temperature, humidity and other values.
Data loggers are designed for measuring, recording, evaluation and subsequent processing of input electrical signals, which are subject to relatively slow changes (> 1s). In conjunction with the appropriate sensors and transducers are suitable for monitoring physical quantities.
The device includes traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO / IEC 17025. The calibration sheet is always loaded as modules. If the defined required configuration of inputs by, calibration certificate proves calibration inputs according to the required configuration – more than one range for each of the 16 inputs.
Common Connectivity Options
Monitoring system MS may be configured for almost any desired measurement application. Sensors can be wired to datalogger in star-like connection as well as in serial. Combination of both is also possible. The monitoring system MS is characterized by a wide range of communication interfaces such as the RS232, RS485, USB, Ethernet and GSM or GPRS modem. Thanks to Wi-Fi routers several measuring systems MS can be wirelessly connected to a network.
Features of Ethernet Interface:
Ethernet interface
Data logger is designed for connection to standard computer network. The 10 and 100Mb/s Ethernet is supported. No need to build new data lines. Thanks this installation cost are essentially reduced and instant easy start of monitoring system operation is enabled.
Modbus protocol
Enables to read actually measured values by means of industrial standard Modbus. Data is available in several formats. Protocol is suitable for implementing of MS data logger to SCADA system.
SNMPv1 protocol
Actually measured values can be acquired by means of SNMPv1 protocol. MIB tables are available for free. Designed especially for IT applications and use in “managed” computer networks.
Fast data download
Record download speed was increased four-times from previous MS5 data logger generation.
SOAP protocol
Protocol designed for data logger integration to own www infrastructure. Available actual values can be captured by www server (Apache, IIS) and processed by the user. Communication protocol SOAP version 1.1. is supported. By means of this protocol data logger sends actual values in preset intervals to specified server.
Syslog protocol
Syslog message is sent after alarm state or data logger error appears. Syslog is compatible with RFC5424.
Data logger sends warning emails up to three different addresses. E-mail is immediately sent after alarm state of monitored technological process appears. User is also informed on error states of device itself (measuring channel error, fulfilling of internal memory, self-test error). SMTP servers requiring autentization are also supported.
XML file
Actual values can be downloaded to XML file. This option is suitable for data logger integration to SCADA systems.
Data logger display
Network parameters can be set directly from data logger display. It is possible to change IP address, subnetwork mask and initial gate.
Secured WEB server
WWW server is built in the device. Here it is possible to monitor actual values, alarm states and information on data logger. Also access password for www pages can be entered. WWW pages are user modifiable. Free SDK description is available to create own www pages.
SNMP Trap
SNMP Traps are sent after alarm state or device error appears.
Database system
Prepared for connection to database system including online values transfer.
WWW remote conditions
Control of remote condition and relays is enabled also via www interface.
