AM3-IP-MB Modbus web server

Control Solutions’ Model AM3-IP-MB includes the i.CanDoIt® Modbus web server, with alarm monitoring, email notification, scheduling and data logging. AM3-IP hardware features 18 universal inputs soft configured as analog or discrete input. AM3-IP also includes four 4-20mA analog outputs, 8 dry contact relay outputs, and 2 pulse counting inputs. Protocol support in AM3-IP-MB includes Modbus RTU (RS485) master, Modbus TCP client and server, and SNMP agent.

The AM3-IP-MB 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 data logging, time & date scheduling, and template or rule based alarm processing with email notification and/or I/O activation in response to events. Data logging simply records the contents of registers on a user specified schedule. Event logging keeps a record of alarm events. Scheduling causes register values to be set according to a schedule. 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 Modbus version of the i.CanDoIt® server features a Modbus RTU Master and Modbus TCP Client and Server. This server is ideal for systems based entirely on Modbus. The server will support polling of up to 50 RTU slaves, and IP connections with 25 TCP/IP devices. The i.CanDoIt® server as a Modbus controller is freely programmable.

Control Solutions’ AddMe III features 18 universal inputs which are context sensitive. When configured as an analog input, the continuously self-calibrating sigma-delta converter produces 15-bit resolution with high noise immunity. When configured as a discrete input, the converter switches to 8-bit resolution at 128 samples per second for fast response.

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 and output type and scaling are configured in web pages served by the internal web server.

The AM3-IP-MB also makes an economical Modbus TCP slave I/O device. Read and write physical inputs and outputs as holding registers. Use the server map to create a virtual Modbus device that lets you access I/O points as any type of register, including Modbus coil. 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 AM3-IP-MB can be used as an SNMP I/O device. Read physical inputs using SNMP Get. Write physical outputs using SNMP Set. 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.
