NETWORK_DELAY - UCTL Manager configuration option
Description
The NETWORK_DELAY option specifies the maximum acceptable delay in transmitting data over the network between the Universal Control Manager and Universal Control Server.
If a data transmission takes longer than this specified delay, the operation ends with a time-out error.
NETWORK_DELAY provides the ability to fine tune Universal Control's network protocol. When a data packet is sent over a TCP/IP network, the time it takes to reach the other end depends on many factors, such as network congestion and bandwidth. If the packet is lost before reaching the other end, the other end may wait indefinitely for the expected data. In order to prevent this situation, Universal Control times out waiting for a packet to arrive in the period of time specified by NETWORK_DELAY.
Note
An understanding of the TCP/IP protocol and the network configuration between the Universal Control Manager and Universal Control Server is required in order to determine the appropriate delay value.
