3.99x modbus tcp timeout setting doesnt work ?

[muratguenduez]

hi bosses,
i have use gprs modem to connect a plc that i used before. i need to increase the timeout for the modbusTCP connection due to carrier issues. default is 3000 and i put it as 20000 but i see the connection error message on basicLabel in 3 second after runing the program!
i think this message should be seen after 20 seconds. why it is still 3 sec ?

or maybe i need to use another technic that i dont know =)

thanks

The problem is still there and the writing problem is slow
