PNRIO Channel Groups

The InputImageValues array Variable contains the Input Process Values of the Input Channels the RIO Channel Group Object represents. The InputImageValues Variable is linked to the associated PnIoTelegramType Input Object using a 0:RepresentsSameEntityAs Reference.

The InputImageQualifiers RioBitFieldVariableType Variable contains a bit field representing the qualifier bits associated with each Input Process Value the RIO Channel Group Object represents. The InputImageQualifiers Variable is linked to the associated PnIoSignalType Input Object using a 0:RepresentsSameEntityAs Reference.

The OutputImageValues array Variable contains the Output Process Values of the Output Channels the RIO Channel Group Object represents. The OutputImageValues Variable is linked to the associated PnIoTelegramType Output Object using a 0:RepresentsSameEntityAs Reference.

The OutputImageQualifiers RioBitFieldVariableType Variable contains a bit field representing the qualifier bits associated with each Output Process Value the RIO Channel Group Object represents. The OutputImageQualifiers Variable is linked to the associated PnIoSignalType Input Object using a 0:RepresentsSameEntityAs Reference.

The array index is used as the unambiguous assignment of qualifier bit and value. The array indexes and the bit numbers of the InputImageValues array and the InputImageQualifiers bit field must be equal to the RioChannelNumber Property Values of the corresponding RIO Channel Objects. The OutputImageValues array indexes and OutputImageQualifiers bit numbers must be mapped to the value range of the RioChannelNumbers of the referenced Output Channels by adding the size of the InputImageValues array.

The RioChannelNumbers of the Input Channels shall have the value range 0 to <size of InputImageValues array> minus 1. The RioChannelNumbers of the Output Channels shall have the value range <size of InputImageValues array> to <size of InputImageValues array + size of OutputImageValues array> minus 1.

If the number of RIO Channels the RIO Channel Group represents exceeds the capacity of the RioBitFieldVariableType (which is 32), as many RioBitFieldVariableType Variables shall be part of the RIO Channel Group Object as are needed to represent the qualifiers of all RIO Channels.

The BrowseNames of the RioBitFieldVariableType Variables shall be extended with a suffix ensuring uniqueness and indicating the section of the bitfield the variable represents in this case, e.g. “_0_31”, “_32_47”, and so on.

The optional Offset Property of the RioBitFieldVariableType shall be provided in this case and contain the start of the range the RioBitFieldVariableType Variable represents. Possible Values for Offset are 0, 32, 64, and so on. The Offset Value added to the bit number is equal to the array index of the corresponding Process Value. For bit fields representing Output Channels the array index must be mapped to the value range of the RioChannelNumbers of the referenced Output Channels by adding the number of Input Channels (see above).
