Specifies the prefix to be used when generating the name for dynamic connection network PUs.

DYNVNPFX=CNV
When the DYNVNPFX start option is not specified, the default value is the three character prefix CNV. The PU names will then take the format CNVxxxxx, where xxxxx is a unique value which is generated and concatenated to the default prefix to create the eight character PU name.
DYNVNPFX=prefix
Specifies a two character prefix that is used to generate the names for dynamic connection network PUs. This prefix will be used if DYNVNPFX is not coded on the virtual node GROUP definition statement. The PU names will take the format ppxxxxxx, where xxxxxx is a unique value which is generated and concatenated to the specified prefix pp to create the eight character PU name.
