8.1 Delay time
Delay time is understood to mean:
– In I/O data mode: delay until an input signal of the input module is output on the asso-
ciated output module.
– In serial data mode: delay until a serial telegram is output via RS-232/RS-485 on the
second wireless module via the serial interface.
Among other things, the delay time depends on the following factors:
– Frequency band used
2.4 GHz or 868 MHz, the higher the frequency, the lower the delay time.
– Utilization of the frequency band
The more wireless networks operating in the same frequency band, the higher the delay
time.
– Network structure (e.g., star or mesh network)
The larger the network, the higher the delay time.
– Distance and set data rate of the wireless interface
The lower the data rate via the wireless interface, the higher the delay time.
–Data encryption
If data encryption is activated, the delay time increases.
