I am having an issue with the serial to ethernet connector software.
My Setup is:
Serial to Ethernet Connector v3.2 build 163
Windows Server 2003 Standard Edition
Description of Issue
I have a Modbus Master device requesting data from a virtual serial port. The virtual serial port is setup in SEC and configured for a TCP/IP Client. The request is then processed and sent down to my electronics and gets a reply.
The way the electronics works is that if a modbus request is not received within 30 seconds then it resets itself and i know this functionality works 100%.
What is happening is that there seems to be some sort of communications lock up with SEC as there is no data returned to my Modbus Master device. Upon stopping the Modbus Master device, the COM port is dropped and after 30 seconds the electronics should reset. This is not happening because the electronics is still receiving valid modbus requests even with the MM device turned completely off.
I used a simple PING x.y.z.a -t which, under normal operation, would show replies for 30 seconds then time out for a period of time before getting replies again. This is also not the case and the Ping always gets a reply therefore the electronics never resets itself which is causing havoc with my system.
Would an updated version of SEC possibly resolve this issue?
Any help would be much appreciated,
