ModbusTCP Delphi component running from WinServer2012

Anders Balslev — Mon, 27 Aug 2018 11:51:56 -0000

On my Delphi Berlin, I have created a (very) simple project where a button is used to connect to a Modbus server (IP, Port 502).
Connection from Win7, Win10 and WinServer 2008R2 runs fine. But when I run it from Win server 2012, the connection takes 5-10 seconds.
Is it possible to get personal support regarding this?

Hi Friend!
I'm trying to develop a simple program using delphi to send and receive data between PC and a device which is using modbus RTU over TCP/IP protocol.
I installed Delphimodubs 1.5.2 in Delphi7 and run ModbusMaster.exe in Indy9.
I enter my device IP and also the register number, and press Read Register button, but I receive an error "Connection Closed Gracefully".
I can connect to my device with SimplyModbus TCP software, would you please check the picture here and help me with the problem?
