SCADA is normally declared as station A However for various reasons it may have been configured as station B In that case the T200 must be declared as station A e Service There are two ways of handling sent frames The send no reply expected service entails no confirmation by the equipment for which it is destined The send confirmation expected service requires confirmation by the destination The send no reply expected service makes it possible to reduce the number of frames exchanged and hence accelerate the flow of information over a link However it should be avoided on noisy transmission media messages are frequently disturbed and in this case the sender does not know that the frame has not been received correctly lt is therefore in practice usable only on dependable media Such media are links such as RS232 links optical fibre links etc on which the speeds are generally very high This explains why it is generally not used However it is possible to configure it e Collision avoidance With certain transmission media collisions can occur between frames sent by the SCADA and frames sent by a far end equipment between frames sent by various far end equipments It is often easy to limit its consequences in the former case A different TL Timeout Link see above will be set at the SCADA end and at the far end equipment end and if two frames come into collision their repetitions will be staggered and the problem will be
