IB-110 Modbus web server

Model IB-110 Internet I/O Board includes the i.CanDoIt® Modbus web server, with alarm monitoring and email notification, plus Script Basic. IB-110 hardware includes 8 universal inputs, a Modbus RTU RS-485 master, plus Modbus TCP client and server and SNMP agent.

The IB-110 can also be used as a Modbus TCP slave I/O device or for SNMP input/output. Access I/O points as Modbus holding registers. Read and write inputs and outputs using SNMP Get and Set.

The goal of i.CanDoIt® is to provide a simple and cost effective facility management and remote monitoring solution suitable for use in small sites. The i.CanDoIt® Modbus web server includes template or rule based alarm processing with email notification and/or I/O activation in response to events. The resulting register manipulation may generate network communication with remote devices, control local I/O, or change setpoints. The i.CanDoIt® is programmable, even though it is rather powerful without programming.

The IB-110 Internet I/O Board (formerly i.Board2) is the second member of Control Solutions' Internet I/O Board family. For all those applications where you need the sophistication of an Internet Appliance but only have a handful of points to monitor, IB-110 is the answer. Now you can combine the universal inputs of the IB-110 with any variety of I/O that communicates Modbus RTU. Web enable power meters, flow meters, or any other smart sensor that talks Modbus.

Control Solutions’ IB-110 Internet I/O Board with i.CanDoIt® features 8 inputs which accept analog input from thermistors or 0-10V sensors, or discrete input from dry contact switches. The IB-110 also provides a serial port supporting Modbus RTU over RS-485.

Input data is presented in scaled integer and floating point format. Linearization tables are provided for 10K and 20K type II, III, and IV thermistors on analog inputs. Input scaling is configured in web pages served by the internal web server.

The IB-110 also makes an economical Modbus TCP slave I/O device. Read physical inputs as holding registers. You can also use Modbus TCP to read and write registers that are mapped to the Modbus RTU master, giving you Modbus TCP access to slave Modbus RTU devices.

The IB-110 can be used as an SNMP I/O device. Read physical inputs using SNMP Get. Via the Modbus RTU mapping, using SNMP to Get or Set registers in slave Modbus RTU devices. Set up SNMP Traps to give you notifications when physical inputs or slave Modbus registers exceed your given threshold.

The i.CanDoIt® Modbus web server includes a large number of predefined web pages for configuration and monitoring. Support is also provided for user defined web pages using HTML and JavaScript. Any of the data registers are accessible to user defined web pages via internal CGI processing of user tags. This allows a fully customized look and feel for the system.

Configuration is done via the web pages. Configuration is saved in the internal Flash file system, and may be exported for backup or for duplicating the configuration in another device.
