8.3.2 Read process

Command message
 TL (device addr.) (start addr. user data) (number of bytes of user data)
Reply message (message core, EKS → PC/control system, see Figure 7 or Figure 8):
For this command there are two possible replies:
 RL (device addr.) (start addr. user data) (number of bytes of user data) (user data)
or
 RF (device addr.) (00
The reply message RL (see Figure 7) stands for correct reception of the data.
If an Electronic-Key cannot be read, an RF reply message is received (see Figure 8). The status number then
indicates the cause of the error.
