Telegram No.6 shows malformed packet
Build Information:
--
AMS protocols of CmdId 9 (ADS Read Write) are shown as Malformed Packet.
Problem is in file
wireshark/plugins/ethercat/packet-ams.c
Line 553:
proto_tree_add_item(ams_adstree, hf_ams_adsdata, tvb, offset+16,
ams_length-offset, ENC_NA);
Should be:
proto_tree_add_item(ams_adstree, hf_ams_adsdata, tvb, offset,
ams_length-offset, ENC_NA);
because offset is still at the correct position.
