=====Requests Configuration=====
 +
----
 +
A Modbus <b>request</b> is a way of obtaining data from Modbus slaves. The master sends a request to a slave specifying the function code to be performed. The slave then sends the requested data back to the Modbus master. You can create a maximum of 64 request configurations for each slave device.
 +
 +
<span style="color:red"> <b>Note: </b></span> Modbus Serial Master uses <i>Register Number</i> instead of <i>Register Address</i> for pointing to a register. For example, to request the <i>Uptime</i> of a device, you must use <b>2</b> in the <i>First Register</i> field.
 +
 +
The Request Configuration list is empty by default. To add a new Request Configuration loon to the Add New Instance section. Enter a custom name into the 'Name' field and click the 'Add' button:
 +
 +

<b>Additional note:</b> by default the newly added Request Configurations are turned off. You can use the on/off slider to the right of the Request Configuration to turn it on:

After having configured a request, you should see a new 'Request Configuration Testing' section appear. It is used to check whether the configuration works correctly. Simply click the 'Test' button and a response should appear in the box below. A successful response to a test may look something like this:

=====Modbus Master Alarms=====
 +
----
 +
<b>Alarms</b> are a way of setting up automated actions when some Modbus values meet user-defined conditions. When the Modbus Serial Master (this {{{name}}} device) requests some information from a slave device it compares that data to with the parameters set in an Alarm Configuration. If the comparison meets the specified condition (more than, less than, equal to, not equal to), the Master performs a user-specified action, for example, a Modbus write request or switching the state of an output.
 +
 +
The figure below is an example of the Modbus Master Alarms list. To create a new Alarm, click the 'Add' button.
