1.2.2 CAN Mode

Supports two 10M/100M adaptive network ports. Supports half duplex and full duplex transmission;

The gateway is a PROFINET IO slave on the PROFINET side;

Supports bi-directional data transmission, also can only be used as CAN receiving or sending;

Supports two run mode, basic and advanced. Basic mode is compatible with versions V1.4.
Advanced mode is the CAN frame filtering function for CAN ID, available for GT200-PN-CO V1.7 and
above.

Under the basic mode, each CAN frame in the PROFINET message is 16 bytes; Each PROFINET data
contains up to 8 CAN frames;
PROFINET input and output bytes can be set in the TIA Portal or STEP 7 modeling software, the maximum
number is:
Max Input Bytes+ Max Output Bytes≤256 Bytes
①
Max Input Bytes ≤128 Bytes
②
Max Output Bytes ≤128 Bytes
Supports only four combinations of input and output bytes:
Input Bytes Output Bytes
16 16
32 32
64 64
128 128

Under the advanced mode, three types of commands are supported, which are called "Producer Filtering ",
"Consumer Filtering" and "Query/Response Filtering". The number of data per CAN frame supports 0 - 8
bytes.
Note: these three types of commands only specify the communication mode of the gateway, not the actual
CAN protocol.
PROFINET input and output bytes can be set in the TIA Portal or STEP 7 modeling software, the maximum
number is:
Max Input Bytes+ Max Output Bytes≤768 Bytes
