19. Disadvantages of Poll Response Disadvantages of a poll/response network · Poll/Response uses %100 of available bandwidth. · The data "Transport" is the "Application". You can't break them apart. · One protocol for all field equipment limits deployment of new technology & impedes migration to new topologies. · It is not a "managed" network. · One-to-One data relationship between the Host and field equipment Master Slave
