[etherlab-users] About Big and little endian.

[Matthieu Bec]

Hello John,

try download using types that fit the target size, that might look like:

./ethercat -p3 --type uint8 download 0x1C12 0 0
./ethercat -p3 --type uint8 download 0x1C13 0 0
./ethercat -p3 --type uint16 download 0x1C12 1 0x1700
./ethercat -p3 --type uint16 download 0x1C12 2 0x1708
./ethercat -p3 --type uint8 download 0x1C12 0 2
./ethercat -p3 --type uint16 download 0x1C13 1 0x1B00
./ethercat -p3 --type uint16 download 0x1C13 2 0x1B08
./ethercat -p3 --type uint8 download 0x1C13 0 2
