TCP IP Modbus
i have implemented TCP IP Modbus communication protocol on Freescale ColdFire micro controller. The TCP IP stack is similar to windows TCP IP stack. For the moment it has just the server part of the protocol this means that other devices can connect to it. My problem is that i don't know how to maintain the connection, because it drops after a while. I had in mind, to use interrupts, but i don't know if this is the right solution. My database has around 2000 modbus signals ... Do you guys have any solution to this problem ?
