This application note was provided by our valued supplier Acromag.
Defining the Problem
Acromag has a peer-to-peer technology called i2o. It allows 2 or more modules to talk to each other transmitting data and no network master or special software is required. I2o operates over Ethernet media; Cat 5 or 6 copper, Fibre Optics, Radios or via Mobile. When operating over a mobile network, it is important to minimise the connection time and amount of data since mobile service providers charge by the amount of data being transmitted.
For example the application below shows an XT1211-000 module with 8 differential current inputs. In addition, it is sampling a 4-20mA signal from a field transmitter and sending the data using i2o to an XT1531-000 with 4 current outputs. The mobile modems at each end are transparent to the Acromag I/O and transmit the data over the network.
Implementing the Solution
Firstly, on the i2o mapping page, the XT1211 input module is configured for each input channel. In addition, a target IP Address and a Modbus Register (output channel) is selected.
Three important features in the XT modules that allow i2o to be utilised over mobile networks to reduce costs.
- Update the time
- This can be any setting from 5 to 65,535 seconds
- This periodic transmission can update the output status based on the input to output scaling
- The XT Modules keep target sockets open
- If they aren’t kept open, then during the i2o messaging a socket is opened, data exchanged and the socket closes
- Percentage Change
- This is the difference. When an I2o message was sent.
- If the input changes by the percentage change threshold or greater, an i2o message will be sent immediately.
