Dear Sir,
Objective : To Implement TCP/IP stack on a ethernet
card.
Sir,We want to communicate between PC
and PLC having an Ethernet card,using master slave technique.
PC is the master,which requests for the register
contents of PLC(Slave) .PLC Ethernet Card and Pc is connected by
BNC connector(RS-485).
PLC having Intel 80c186 processor and 32Kb EPROM
and Intel 82595Tx card controller which is responsible for
transmission
recieving of data.
To communicate betwween two (PC and PLC) we need to
implement Modbus/TCP protocol.
Since our Ethernet card doesnot support any
protocol first we have to implement TCP/IP.
How can I Implement it?
With regards,
RAJARAM
