EtherCat master : IODrvEtherCat 3.5.10.0
Slave device : two digital input modules (EL1008), one digital output module (EL2008 ) and one Ethercat coupler.
Kernel: QNX + codesys runtime (3.5.10);

As long as running the project, there is a warning --- the number of slave has changed or is different from the configuration.
Could you tell me the reason why this warning occurs ?
