Store this angel in big sizeTMO-100, Radio modem for abstracts advice in Tetra infrastructures

Different applications, and altered bounded regions, accept altered requirements for automation protocols. Energy utilities in Germany and Europe use accepted standards (IEC 60870-5-101 or IEC 60870-5-104). In Asia and the U.S. they about use the Modbus RTU or DNP3 protocol. Less able-bodied accepted is the PakBus Sinaut agreement from Siemens, which is primarily acclimated in the baptize and sanitation industries.

The Modbus RTU Protocol is decidedly acceptable for apathetic or wireless manual paths, due to its convenient and solid structure. However, compared to added protocols, the Modbus RTU Protocol has the disadvantage that the outstation alone works by polling, which is the alternate polling of anniversary alone base by the adept station. Other protocols accept the advantage of the outstations application event-driven messages, rather than cat-and-mouse to be polled by the master. Through this process, alarms can be appear apart from the polling aeon of the Master device.

The TETRA TMO-100 supports pro¬tocols such as Modbus, PakBus, the Sinaut agreement from Siemens and abounding more. The TMO-100 does not about (but can if required) plan with GISSI, but anniversary individual abstracts set will be beatific to the one outstation it is addressed to. This is a above account of TETRA infrastructures, due to the top arrangement amount if sending accumulation messages, rather than careful messages. Another affection that reduces the arrangement amount is the chip adapted LZ77 abstracts compression mechanism.

For the Modbus RTU Protocol the TMO-100 offers a appropriate advantage to accomplish it accessible to action event-driven alarms on a ad-lib basis. For this the outstations can be ordered with an alternative E/A Board in accession to their consecutive interfaces. These inputs can be acclimated to automatically forward cachet all-overs letters to the adept station. This adept base food the alarms in Modbus registers, area they can be accessed at any time admitting the affiliated master-PLC or the SCADA Server. This makes it accessible to acknowledge to alarms or malfunction letters at any time, in the aforementioned way as unsolicited messages.

In accession to the consecutive asynchronous protocols, the TMO-100 can aswell action UDP- and TCP-protocols. In this case, the accessory operates as a TETRA router.
After the accessory is angry on, a PPP-connection is automatically accustomed to the Tetra infrastructure, and the assemblage receives an IP-Network abode from the Tetra Switch. The TMO-100 anon forward IP abstracts from the bounded Ethernet interface to the TETRA-IP-world, and carnality versa. For this the TMO-100 uses NAT, Port Forwarding and Port Translation, which turns the accessory into a fully-featured TETRA-router. For the user affiliated on the bounded IP-Port, the Tetra basement is not in actuality visible. He artlessly connects the PLC to the Ethernet anchorage and, afterwards ambience up the IP-Address, will be able to acquaint with added accessories or the SCADA Server aural the TETRA basement (and also, if enabled, above that).
The accessory can be configured either via the anchored Web server, the Modbus RTU Protocol application its consecutive interface, or the Modbus/TCP via its bounded Ethernet interface, or accidentally via the TETRA infrastructure.

For applications that charge anchored agenda or alternation inputs and outputs (I/O) aural the device, the TMO-100 can aswell be delivered with an alternative I/O-board with 16 agenda inputs, 8 (optional 16) agenda outputs, and 4 analog inputs (12 Bit resolution, 0-20mA/4-20mA). As able-bodied as the 16 bifold inputs, the accessory is able with 8 accident counters and 8 timer counters. All inputs and outputs are isolated. Access to the inputs and outputs takes abode via the Modbus-RTU or the Modbus/TCP Protocol, and can be accomplished locally or via the TETRA infrastructure, application either SDS or Packet Data.

Another important appropriate for abstracts modems is the adeptness to set up a articulation connection. Using an eight-pole RJ45 plug, an RSM (remote apostle microphone handset) can be absorbed to the TMO-100. When the PTT (push to talk) button on the RSM is pressed, the modem disconnects all abstracts access (SDS, CSD, PSD) and automatically switches into articulation mode. A articulation alarm is set up to either a preset ISSI or GSSI. After finishing the conversation, the abstracts advice will automatically be restarted by the device. When switching from articulation approach to abstracts approach or carnality versa, the modem can still forward a cachet bulletin to the ascendancy center.

Since 25 years the aggregation is acknowledged in bearing and distributing radio telecontrol, abnormally radio and radio-modem solutions for abstracts transmission.Since 1996 Funk-Electronic Piciorgros GmbH has focused on automatization, baptize and decay baptize ascendancy for electricity and account companies and the industry in general.
