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:
