We have configured our board as modbus COM Port Master and our I/O devices as COM Port slaves. So we have data as tags read by com port master and now we want to forward those data to an uplink network like SCADA through modbus protocol , configuring our Board as TCP slave and SCADA as TCP master . For that we need to link COM port master data with TCP Slave. and it keeps showing yellow triangle on tcp slave, what does that mean and how to configure it?
