Interconnecting the receive buffer
The inverter writes the received data in the receive buffer:
● PZD receive word 1 ... PZD receive word 12 double word in r2060[0] ... r2060[10].
● PZD receive word 1 ... PZD receive word 12 word in r2050[0] ... r2050[11].
● PZD 1 ... PZD 4 bit-by-bit in r2090.0 ... r2090.15 to r2093.0 ... r2093.15
The position of the mapped objects in the receive buffer is displayed in:
● r8760 for double word switching
● r8750 for word switching

Interconnecting the send buffer
The inverter sends the data from the send buffer as follows:
● p2051[0] ... p2051[13] in PZD 1 ... PZD 14 (indication of the actual link in r2053[0 ... 13])
● p2061[0] ... p2061[12] in PZD 1 ... PZD 14 (indication of the actual link in r2063[0 ... 12])
