Abstract :
Design practices are outlined which are intended to improve the throughput from PLCs through LANs to display panels while decreasing communications to the PLCs. The result of less activity on the network will also boost the scan speed of the PLCs, which have to do the real work. Ordinary techniques of using mailboxes in an intermediate device, as well as updating by exception through the use of ladder logic, are briefly discussed.<>
