             Summary: Reading data from PLC via Modbus with Camel using timer
                 Key: PLC4X-292
                 URL: https://issues.apache.org/jira/browse/PLC4X-292
             Project: Apache PLC4X
          Issue Type: Wish
          Components: Integration-Camel
    Affects Versions: 0.8.0
            Reporter: Dmitry Shagiakhmetov


I want to get data from plc with period = 1 ms. I try it using consumer:
{code:java}
val modbusConsumerEndpoint = Plc4XEndpoint(modbusEndpointUri, plcComponent).apply {
 tags = mapOf(fieldName to "input-register:$plcInputPort")
 period = 1
}

from(modbusConsumerEndpoint)
                .process {
                    it.message.body = (it.message.body as Map<String, Any>)[ModbusEndpointParams.fieldName]
                    it.setMainBody(ctx)
                }
                .marshal().json()
                .setHeader(KafkaConstants.KEY, constant(""))
                .to(mainKafkaEndpoint){code}
But I have only one loop. {color:#000000}*Plc4XConsumer* may work with trigger, but I couldn't find any examples for that.
{color}

{color:#000000}Either I try to use camel chain with timer:{color}
{code:java}
from("timer:foo?period=1")
 .process {
 it.message.body =
 mapOf(fieldName to "input-register:$plcInputPort")
 }
 .to("plc4x:modbus://uri"){code}
But *Plc4XProducer* works only for writting. I solve this problem by creating own Endpoint with custom Producer includes ReadRequestBuilder extend  Plc4XEndpoint and Plc4XProducer. It looks not like production decision.

What is a right way to do this task?
