Active I/O Messages

In this scenario, we have a pressure sensor attached to the AI channel of the ioLogik; a DO channel

is connected to a switch on an air pump. When the pressure of the tank is low, the ioLogik will start

pumping. At the same time, the ioLogik will send a TCP message to the central office, indicating

that the pump is ON. When pressure levels become high, the ioLogik will shut down the pump by

turning off the DO. Another TCP message will then be sent as well. We want the ioLogik to send a

TCP message that indicates the exact time the switch is turned on.

Product Model: ioLogik E2242

Rule 0:

IF AI-0 <= 8 mA, THEN DO-6 = ON

Rule 1:

IF AI-0 >= 18 mA, THEN DO-6 = OFF

1. In ioAdmin, make sure that you have logged in on the Server Settings tab. Go to the I/O

Configuration tab and set the AI-0 channel to 4-20 mA mode.

2. Go to the Click&Go Logic tab. On the Global Variable tool bar, click on the Active Message

Server button. Configure the Destination Address, Message Protocol, and Message Port. Click
