Product Information


Modbus RTU Slave Option for IntelliLogger IL-Mini™

An IL-Mini™ equipped with the Modbus Slave option and connected to a Modbus network can be programmed to expose internal Register values to connected Modbus Master devices (e.g. controllers, displays, etc). With this feature, the IntelliLogger IL-Mini™ can be sampling temperatures, pressures, flows, etc from hardwired inputs… performing calculations and also serving the Register values to a connected Master device over the Modbus RTU network.

Configuration of the Registers is simply done from within the HyperWare-II icon-based programming environment. Register addresses are assigned to each of the icons within the Program Net for which register value sharing with a connected Modbus Master device is desired.

IntelliLogger IL-Mini™ Modbus Registers can be configured to allow a Master device to access the following IntelliLogger IL-Mini™ parameters:

Current Value Readings

Current values, whether they be analog input signals, calculated values, event states or any other I/O parameter can be read from the IntelliLogger IL-Mini™. Modbus access is implemented by the addition of Probe Point icons into the IntelliLogger IL-Mini™ Program Net and then assignment of a Modbus register number to the Probe Point.

Remote Contol Icon State Update

Remote Control (On/Off) icon states within the IntelliLogger IL-Mini™ Program Net can be updated by writing to IntelliLogger IL-Mini™ Modbus Registers . This facilitates remote On/Off control of actions within the IntelliLogger IL-Mini™ from a remote instrument over the Modbus link. These On/Off actions can change the operation of the IntelliLogger IL-Mini™ program while it is running as well as control physical outputs on the IntelliLogger IL-Mini™.

Remote Constant Update

Upon command from a Modbus Master device, the Remote Constant icon within an IntelliLogger IL-Mini™ Program Net can be updated. This allows a remote Modbus Master device to change set-points, alarms, constants used in calculations, etc via the Modbus link.

The IntelliLogger IL-Mini™ can now be ordered with the following Modbus support options:
