Communicating with IEC 870-5-104 protocol

Hi all,
I try to connect two different PC in master and slave modes and use to IEC870 v2.21 driver.
I have configured them one PC for IEC 870-5-104 MASTER and one PC for IEC 870-5-104 SLAVE
Slave Port is 2404
I set the address variable(Tag) in Slave and get the value from Slave to Master but I don’t get value of Slave
Please support for me !!!

Hi tieungunhi59,

I suggest take a look at the article and watch the driver configuration parameters

It is also important to read the following article and verify if the communication problem is not being caused by external issues to the driver.
