S7 programmers regularly ask themselves “How can I measure the transmission speed between PLC and PC?” Unfortunately it is not possible to give a general answer, because the speed depends on several factors. Among other things, the speed of the PC, the S7 PLC used and the network play an important role. But with the new extension of our free PLCScanner you can measure this very easily.
For example, if a machine produces a part every 200 milliseconds, then the transmission of the associated data may take a maximum of 200 milliseconds. Until is of course less. Otherwise there will be overlaps and the resulting loss of data.
With our PLCScanner, you can now easily measure how long it takes to transfer the data to your system or machine.
