Product data sheet
Shenyang Guangcheng Technology CO.LTD.
If GCAN-IO-8000 is equipped with multiple sets of GC-2008 modules at the same
time, then we number them according to their distance from GCAN-IO-8000, from
near to far, and the nearest one is No. 1. The RPDO data received by the
GCAN-IO-8000 coupler needs to be sent according to the following table. For
example, when the GCAN-IO-8000 node number is 3 and 9 GC-2008 modules are
installed at the same time, you need to send two sets of data with frame IDs 0x203
and 0x303 to control all 9 modules. Among them, the eight data bytes with the frame
ID of 0x203 correspond to the GC-2008 module No. 1-8 in turn; one data byte with
the frame ID of 0x303 corresponds to the GC-2008 module No. 9.
Table 4.2 Correspondence between multiple sets of GC-2008 modules and CAN data
If GCAN-IO-8000 is equipped with multiple sets of GC-3804 modules at the same
time, then we number them according to their distance from GCAN-IO-8000, from
near to far, and the closest is No. 1. The TPDO data sent by the GCAN-IO-8000
coupler will be sent according to the following table. For example, when the
GCAN-IO-8000 node number is 3 and four GC-3804 modules are installed at the
same time, you will receive four sets of data with a frame ID of 0x183. Among them,
the eight data bytes with the frame ID of 0x183 correspond to the four channels of the
GC-3804 module in sequence; the eight data bytes with the frame ID of 0x283
correspond to the four channels of the GC -3804 module in sequence.
Table 4.3 Correspondence between multiple sets of GC-3804 modules and CAN data
If GCAN-IO-8000 is equipped with GC-1008 module and GC-3804 module at the
same time, then we number them according to their distance from GCAN-IO-8000,
from near to far, and the nearest one is No. 1. The TPDO data sent by the
GCAN-IO-8000 coupler will be sent according to the following table. For example,
when the GCAN-IO-8000 module node number is 3 and it is equipped with 3
GC-1008 modules and 1 GC-3804 module at the same time, you will receive two sets
of data with frame IDs 0x183 and 0x283. The data correspondence is shown in the
table below.
