MT-251 module has been designed for wireless integration over 2G/3G network of various remote devices (e.g. measuring units, PLC controllers, I/O stations, operator panels) equipped with serial port RS-232, RS-485 or Ethernet port. With compact, robust design, attractive technical features and easy to use configuration tools the MT-251 gateway is an optimal solution for demanding wireless telemetry, control, diagnostic, surveillance and alarm systems. Module is equipped with 3G modem and optionally can be produced with MIM (Machine Identification Module) soldered to PCB replacing or backing-up standard SIM card. It can be powered from DC voltage source (18-55 VDC) and additionally it equipped with intelligent charger designed to manage of external SLA backup battery.

MT-251 can be used as wireless, “transparent” serial and Ethernet port, but it can also play a role of local Master querying periodically an external device for user defined recourses. In such case MT-251 creates in memory a mirror of the external recourses and detects alarms, state changes and fulfilled logic conditions incorporating raw and calculated values. Data are transmitted via 2G/3G network according to user defined rules. Data may be logged with precise timestamp in non volatile Flash memory according to configured schedule or on event.

Resources:

  • USB port for local configuration and programming
  • Interface for backup 6V SLA battery – charging support
  • Internal flags and registers for user application program
  • Firmware Flash memory with remote update capability
  • Data logger supporting microSD card
  • Option of soldered MIM card replaced SIM
  • RTC with external synchronization functions

Functionality

  • Transmission mode: 2G/3G packet transmission, SMS, Ethernet
  • Access to remote recourses using standard protocols MODBUS RTU and MODBUS TCP
  • Intelligent packet routing and Multimaster support in MODBUS mode
  • Transmission of data from external devices connected to serial and Ethernet port
  • External resources mapping (mirroring) for event detection and triggering
  • MT2MT buffer for direct data sharing between other MT telemetry modules
  • Multibroadcast for transparent mode
  • SNMP ver. 1 protocol support (included traps and polling functionality). Module operates as a SNMP agent – device which can be polled by server and can send unsolicited information (traps) to server. External resources mapping (mirroring) for event detection and triggering
  • Data logger recording on microSD card with 0,1 sec resolution
  • Programmable control logic using I/Os, timers, counters, flags and register for triggering events (data transmission/ recording, SMS transmission, e-mail transmission, setting output and internal register, etc.)Configurable SMS messages triggered by alarms and scheduled
  • Dynamic Fields in SMS text, support for symbolic names and macros
  • Event based transmission (unsolicited messaging) triggered by change of binary input/output state, internal flag state, by true condition.
  • Remote configuration and programming via 2G/3G network
  • Configurable access security – list of authorized IPs and telephone numbers, optional password
  • DIN rail mounting
  • 18-55 VDC Power supply
  • Built-in management of external SLA backup battery
  • Built-in advanced auto-diagnostics
  • Spring terminal blocks
  • User friendly configuration tools and communication driver (OPC and RDB support)
