17. 6 samples can be sent in any particular data packet 4 1 Small Packet Size Advantages Data is returned to the host computer system very quickly ideal where short response time is requires i e real time operations are essential Dis advantage small packet size results in high network overhead 4 2 Large Packet Size Advantage Large packet sizes provide efficient use of network traffic Data from each analogue channel is easily packed and sent across the network Disadvantage Data packets are sent slowly across a network making them ideal for use in control system loops PID etc 4 3 Broadcast vs Single Host Operations When a single User Operator is accessing data from the instruments and standard PodMng application software is in Run mode the instruments send data only to the single computer system All other computers connected to the network using a standard network interface card will ignore the data from the NetPod The software contained within the network card filters out instrument packets from the standard user operations i e print servers etc and enables normal network operations to be undertaken However should more than one user be running the Pod Manager software then the instruments sends special packets called broadcast packets instead of the normal datagrams The broadcast packets will be received by every computer system connected to the network which results in a small overhead in processing for machines that
