IntelliLogger - Modbus RTU Connected Flow Power and Wireless Sensor

IntelliLogger™ Modbus Capability

The IntelliLogger now supports the full suite of Modbus protocols for data acquisition.. Modbus RTU Master and Slave as well as Modbus TCP Client and Server.  With this Modbus capability, the IntelliLogger can be configured to sample inputs from Modbus enabled devices such as intelligent sensors, power meters, gas analyzers, flow computers, gen-set controllers, etc.  Via this industry standard communication link,  the connected device memory registers can be read by the IntelliLogger and processed within the IntelliLogger Program Net in the same ways that hardwired signals (eg 4-20mA, Vdc, etc) are handled.  The key difference is that the Modbus interface is via a digital serial link between the IntelliLogger and one or more Slave/Server devices rather than the mentioned analog signals.

Alternatively, the IntelliLogger can be configured as a Modbus RTU Slave (or Modbus TCP Server) and share its own internal Modbus registers for interrogation or update from other networked Modbus Master (Client) devices.

For those new to the capabilities of Modbus, a Modbus educational overview is presented in the Modbus Protocol Background tab below.

Modbus Interface with the IntelliLogger™

The IntelliLogger can be integrated into a Modbus network providing a whole new set of data collection and reporting capabilities. With the new Modbus interface options, the IntelliLogger can be quickly programmed to perform functions such as:

• Query connected Modbus ‘smart’ transducers for Register values and utilize them in the IntelliLogger Program Net simultaneously with other hardwired inputs.
• Expose internal registers to other Modbus devices for use in their algorithms. Shared IntelliLogger Registers can be input, output and/or calculated values.
• Remotely control IntelliLogger outputs via Modbus communications from a Modbus Master
• Serve Web pages with embedded data collected from Modbus Slave devices
• Adjust IntelliLogger operation via Modbus communications during IntelliLogger program execution
• Send status and/or alarm emails (or SMS) with embedded readings and/or attached data collected from Modbus Slave devices
• Acknowledge IntelliLogger programmed alarms
• Change IntelliLogger alarm thresholds during IntelliLogger program execution
• FTP readings collected from Modbus Slave/Server devices as well as hardwired inputs

The IntelliLogger can now be ordered with the following Modbus communication options:

• Modbus RTU Master
• Modbus RTU Slave
• Modbus TCP Server
• Modbus TCP Client

Additionally, the IntelliLogger can be ordered with the following combinations of Modbus in a single instrument:

• Modbus RTU Slave AND Modbus TCP Server and/or TCP Client
• Modbus RTU Master AND Modbus TCP Server and/or TCP Client

• Query connected RTU Slave/Server device registers
• Supports long distance wiring runs to Slave transducers
• Acquire register values from multiple connected Slave/Server devices
• Utilize Slave/Server registers in Program Nets similar to hardwired inputs
• Share logger register values with Master/Client devices
• Read and Write to Slave/Server device registers
• Flexible and Simple configuration of Slave/Server register parameters
