GE IS215VPROH1BD module

GE IS215VPROH1BD module

In its default configuration, a receive window and timestamp option are defined based on RFC1323 (a protocol standard). When an error packet is generated, only frames marked as lost or incorrect in the window buffer are retransmitted, rather than all data. Thus improving the efficiency and reliability of TCP transmission. In special circumstances, if the system generates a large number of error packets, the TCP buffer window will immediately be filled with error labels, leading to buffer overflow. Due to the VxWorks operating system not having the ability to automatically clear the buffer, communication failures can occur, and DCS displays bad points. At this point, only by restarting a pair of controllers can the buffer overflow error be cleared. From this, we can infer the cause of communication failures: due to the special nature of GE HMB compilation, GSM services must be interrupted during the compilation process, which will inevitably generate a large number of erroneous data packets, causing buffer overflow of the OVATION controller, thereby causing communication failures. Solution: After repeated experiments, we have come up with a solution that balances two control systems: not enabling the reception buffer of the OVATION controller. In the VATION manual, we obtained a configuration method for changing the default receive buffer of the controller: do not enable this option in the controller startup configuration document. Although this sacrifices some communication performance, it can avoid buffer overflow errors
