Assigning an Interface Block

The glp/0/T6tWyga/rq/dev/modbus/amik_rtu/if/block/1 topic addresses a particular modbus amik_rtu interface block 1. This request topic accepts assignment of a complete or a partial amik_rtu modbus interface block.

The following shorthand notation illustrates the assignments of a partial object to this topic, affecting only the monitor rate value.

'{"Volts_1":{"monitor":{"rate":20}}}'

Monitor rate value gives the periodic updates to monitoring service. We can set the monitoring rate property value in multiple ways.

The following examples all yield the same result:

Changing Property Value of Monitor Rate

The following examples changes the property value of monitor rate. The response shows the updated monitor rate value.
