Christofer Dutz commented on PLC4X-314:
---------------------------------------
Ok ... in your capture you have a recording of communication with 4 S7 400
devices with a pdu size of 480 ... that should be more than enough to carry the
request you want to send. Is is possible that in your tests that are causing
problems you are using a S7 1200? ... cause if I use one of those I need to
split the request up into multiple requests.
