9300 Servo PLC and ECSxA!
Tip!
Possible causes for incorrectly received telegrams can be:
·
Missing bus termination
·
Non−sufficient shielding
·
Differences in potential with regard to the earth connection of the control electronics
·
Bus load too high. See chapter 3.13.3, "Bus load by the PLC". ( ^ 3−15)
