AxisLog Mini is a data logger hardware which connects to the equipment control system over Modbus.
PRODUCT
AxisLog-Mini
(Data logger hardware)
AxisLog Mini acquires and stores up to 40 Modbus parameters and periodically uploads these over FTP to a central server over GPRS. It sends SMS alerts to user on pre-configured conditions/events. It can be configured through RS232 serial port, over FTP and selectively over SMS.

Interfaces
- Serial interface: RS485, half-duplex (2-wire) port. RS232 option instead of RS485 is also available
- Configurable standard baud rates (2400 to 115200)
- Supported industrial protocols
- Data acquisition from third party devices over Modbus RTU (master only), Modbus ASCII as per Modbus Application Protocol V1.1b
- Other protocols such as MPI, PPI, DF1 using external converter
- Data acquisition from sensors requires external signal conditional modules to be interfaced over Modbus
- User interface RS232 for configuration/display of status. The tags/status/data can be viewed in tabular format using hyper-terminal over RS232
- Supported number of parameters 40 parameters (in any combination of analog or digital). Each analog parameter is 32/16 bit depending on the data type Data Acquisition and Storage
- Data logging frequency (configurable): 2 logging groups - each can range from 1-99999 seconds
- Data logging interval (configurable): 6 logging groups - each can range from 1-99999 seconds
- Data logging: Log all polled values
- Trigger for block read
- Data acquisition: single register read/block read
- Mini does not support combination of several DI parameters to form one Analog parameter. However this combination can be done at the slave device Data Transfer
- Data file structure: individual .CSV files for each tag. CSV file consisting of equipment name, value, time, and date stamp. The files can be directly viewed in Microsoft Excel or suitable viewers
- Data transfer protocol: FTP
- FTP transfer interval (configurable): 2 FTP interval groups - each can range from 00:01 to 99:59 (HH:MM format)
- Storage device and capacity: non-volatile flash memory - 7,00,000 records
- Server connectivity: GPRS Other Details
- Configuration: AxisLog Mini can be configured in 3 ways: Configuration file download through RS232 interface, configuration file download/upload over FTP, select configurations by SMS from 2 configured users
- Maintenance and diagnostics: system status (date / time, Modbus status, and FTP status) available over RS232 (hyperterminal)
- Diagnostic mode for troubleshooting of data memory operations, RTC, communications, and SMS logic
- Error and event logs sent over FTP to server, every FTP interval
- Security access control: 2 levels of access (for example: operator, supervisor)
- Tag read/write: tag read or write possible through SMS from 2 authenticated users
- SMS alerts: Send SMS on alarm condition maximum 10 users and 15 alerts. Alert conditions are user configurable. Hardware/OS
