Data exchange
Twentybytes always must be sent and received for communication with the PNOZmulti.
Ethernet/IP
The input/output data from the PNOZmulti can be polled using the assembly object (Class
04h).
} Data from the PNOZmulti are requested with instance64h.
} Instance 96h writes the data from the Ethernet IP scanner to the PNOZmulti.
Modbus TCP
No connection needs to be configured for the PNOZmc8p. Port 502 is used in accordance
with the Modbus TCP specification.
The Modbus TCP supports the following function codes:
3,16 and 23 (refer to the document "PNOZmulti Communication Interfaces" for details of
additional function codes)
The address input range begins with Register 0. The address output range begins with Re-
gister 1024. The Byte sequence for a Word is High Byte/Low Byte
Word
Left Byte Right Byte
Low Byte
(Bit 7 ... 00)
High Byte
(Bit 15 ... 08)
Input and output data
The data is structured as follows:
Input area
The inputs are defined in the master and transferred to the PNOZmulti. Each input has a
number, e.g. input bit 4 of byte 1 has the number I12.
