The following parameters are used to con󶍾gure PDO mapping. Every two parameters
form a group. 0-23 indicates I/O Messages Mapping(T->O) and 24-47 indicates I/O
Messages Mapping(O->T). Data[0]=0x44 and Data[1]=0x70 shown in the 󶍾gure represent
that TPDO1 is mapped to U0-68.
By default, I/O Messages Mapping(T->O)[0] is mapped to U0-68, I/O Messages
Mapping(T->O)[1] is mapped to U0-69, I/O Messages Mapping(O->T)[0] is mapped to
U3-17, and I/O Messages Mapping(O->T)[1] is mapped to U3-16. These four parameters
cannot be changed, otherwise, a fault may occur. Other parameters can be user-de󶍾ned
as required.
MD500:I.Data and MD500:O.Data are IO data during data transmission. The written
values in O.Data are written to the parameter corresponding to the mapping that is
con󶍾gured in the preceding process. Con󶍾gured parameters corresponding to I/O
Messages Mapping(T->O)[0] will be uploaded to I.Data regularly.
