PBM_RD_ERRCODE | PROFIBUS

Specify the library handle. See "Library handle" for details.

Specifies the pointer to the T_ERR_CODE structure to store the acquired parameter.
The T_ERR_CODE structure is as follows.

typedef struct _T_ERR_CODE{
    unsigned short  param_err_code[4];
    unsigned short  inter_err_code[4];
} T_ERR_CODE;

param_err_code[0]

0	:	normal
		("code2" is not used)
1	:	There is a slave that has illegal total of DI/DO size.
		When the total of DI/DO size in a certain slave exceeds 244 bytes.
		("code2" indicates a corresponding slave. And if multiple slaves are corresponding slave, it indicates a slave of the smallest number.)
2	:	There is a slave that doesn't have slots.
		("code2" indicates a corresponding slave. And if multiple slaves are corresponding slave, it indicates a slave of the smallest number.)
3	:	There is a slave that exceeds the permissible size of slave parameter.
		("code2" indicates a corresponding slave. And if multiple slaves are corresponding slave, it indicates a slave of the smallest number.)
4	:	There is an invalid slot that has an invalid module data.
		(The upper byte of "code2" indicates a corresponding slave and the lower byte indicates a corresponding slot. And if multiple slots are corresponding slot, it indicates a slot of the smallest number.)
5	:	There is an invalid slot that exceeds the permissible total size (244bytes) of DI/DO data.
		("code2" indicates a corresponding slave. And if multiple slaves are corresponding slave, it indicates a slave of the smallest number.)
