- FlexSerial – programmable handling of non-standard serial protocols
- Remote configuration, programming, diagnostics and firmware upgrade via GPRS
Functionality
- Transmission modes:
- GPRS – packet transmission
- SMS
- CSD – circuit switched data transmission (in modem mode only)
- Access to module resources using standard protocols MODBUS RTU and MODBUS TCP
- Event based transmission (unsolicited messaging) trig-gered by change of binary input state, internal flag state, by reaching alarm level of analog input, by true condition
- Programmable control logic using I/Os, timers, counters, flags and registers for triggering events (data transmis-sion/recording, SMS transmission, e-mail transmission, setting outputs and internal registers, making calls, etc.)
- Intelligent packet routing and Multimaster support in MODBUS mode
- Configurable SMS messages triggered by alarms and scheduled
- Dynamic fields in SMS text
- Configurable alarm levels, hysteresis, deadband and filtration for analog inputs
- Data and event recording on micro SD card with 0,1 sec resolution
- Transmission of data from external devices connected to RS-232/485 serial port
- 5 V feeding provided for external device connected to RS-232 serial port (e.g. operator panel, GPS receiver)
- Configurable events based on mirrored resources of external devices
- Remote configuration and programming via GPRS/ HSPA
- Configurable access security – list of authorized IPs and tel. numbers, optional password
- DIN rail mounting
- Supply voltage 12/24 VDC (24 VDC in case of using connected external battery)
- Built-in management of external SLA backup battery
- Built-in advanced auto-diagnostics
- Detachable terminal blocks
