55 High
speed data forwarding
55.1 High
speed data forwarding - connection
This task is executed by PDAServer.exe, it may achieve millisecond level forwarding. The PDA server adds a multi port network card. In principle, the data required by other systems is not directly connected to the L1 controller, but is obtained through PDA forwarding. Different network segments are forwarded through different network ports, which can save a lot of PLC resources. The first forwarding method is set through Config.csv, as shown in the figure below, with the forwarding IP, forwarding destination IP, and forwarding cycle set. This method can only forward to one place.
Figure 1 Setting up high-speed data forwarding to a location The second method is set through toIP. ini, which allows for high-speed forwarding to up to 10 locations, forward the received data at once when the forwarding cycle is 0.
Figure 2 Setting up high-speed data forwarding to multiple locations 55.2
High speed data forwarding - hybrid
This task is executed by Retransfer.exe, the forwarding period is an integer multiple of 10ms. Retransfer.ini is the configure file. Type 0: Combine data from different connection channels and send to the destination IP using UDP. The configuration example is as follows, the period is used to set the period (ms). Type 1: Retransfer all data of the connection, the efficiency is lower than the previous method.
