subject: The Functionality Of Telemetry Module Imod With Gsm Modem [print this page] iMod allows you to transfer data both via Ethernet, and in the networks of mobile communications standard GSM, while ensuring that: a router function RS-232 / RS-485 / Ethernet / GPRS. Modbus function router / gateway access via FTP, WWW, Telnet.
It is possible to ensure remote configuration and management. Transmission of data on GPRS technology can be used as an additional channel of communication in case of malfunction wire communication line.
The module provides iMod Multiplexing, so the modem supports three simultaneous channels of access, one of which is used for data exchange, the other for the SMS, the third as a backup.
At the same channels do not influence each other, so both can be receiving and transmitting data, short text messages, as well as the work of the third channel, which you can use to perform user-defined functions.
Thus, for example, the transmission of the SMS system failures will not be postponed even if the other channels are involved in a given time to solve other problems.
The telemetry module supports iMod service DynDNS, so you can reduce the cost of monitoring and control systems. DynDNS - free server DNS, service domains. Learn more about this service can be read on the page devoted to this issue.
Versions of industrial computers NPE
NPE-series devices, and telemetry modules of the iMod have a great set of versions that are functional, but the principle of marking devices for both series are identical. So are lots of versions of the digital indices 9100, 9200, 9201, 9300, 9400, 9401. Numbered, taken by the developer, defines the amount of available memory chips in the device, as well as the number of analog inputs.
After the digital signs may be present letter subscripts R and (or) W, denoting: R - in the version (version) provides 2 relay (switching) output; W - in the version includes support for a protocol-Wire (OneWire).
Finally, in versions that contain a module composed of a modem, a hyphen indicates the letter of GPRS or EDGE, depending on which technology supports the GSM modem, GPRS or EDGE, respectively.
For example, NPE-9300 - version (option), which contains modus rtu the following basic functionality: two RS-232 port, one RS-485 port, the interface is Ethernet, 8 digitalm-bus inputs, 6 digital outputs, the Flash memory of 1 GB. At the same time, for example, NPE-9300W-EDGE in addition to the basic functionality version of NPE-9300, adds support for one of the inputs of Protocol 1-Wire (OneWire) and contains a built-in modem with support for EDGE.
Differences between the versions of the NPE, specifications, operation, appearance and purpose are detailed on the official website of scada the manufacturer, containing, among others.
