Function Block BT_PB345:
The function block BT_DP345 is used to decode the transfer protocol
of the operating devices. It ensures consistent data transfer.
When you program the controller, note that a total of 64 bytes as of the
address DB[P2] W[P3] are reserved for processing the protocol. Other
program components cannot use this area!
The function block BT_PB345 uses the following parameters:
Parameter Function
P0 EZ Base Address
P1 AZ Base Address
P2 Data block for storing the EZ/AZ data
P3 Base Address in Data Block [P2]
P4 Telegram Length
corresponds to the number of EZ/AZ data of the slave
configuration (8, 12, 16, 20, 28, or 32 bytes)
