Variable: nviNV_config
Format: UNVT_DPI_CONFIG
Explanation:
This network variable input provides information on how parameters should
be mapped to network variables. The NVI contains two fields:
• NV_index
• DPI_parameter
To check an already existing configuration, use the following procedures:
A. To check which DPI parameter a network variable is connected to, use
nviNV_config with the following data:
UNVT_DPI_CONF.NV_index = NV_index to check
UNVT_DPI_CONF.DPI_parameter = 65535 (decimal)
B. To check which network variable a DPI parameter is connected to, use
nviNV_config with the following data:
UNVT_DPI_CONF.NV_index = 255 (decimal)
UNVT_DPI_CONF.DPI_parameter = DPI parameter to check
The result of the requests above are placed in nvoFB_config. If there is no
configuration available, 0 (zero) is returned.
Valid Range:
NV_index out: 14…20
NV_index in: 31…36
