Dual Bus Number
Figure 15: Genus Bus Number Assignment
BUS.NUM The bus number provides a bus identity to various software
components. Each dual bus must have a unique value that is in the
range of 0 to 15.
PNC Configuration
Figure 16: PNC Assignments
BUS.PNC_SLOT
The PNC slot number is used to identify the slot location in which
the PROFINET controller is installed. (Up to four PROFINET
controllers may be installed in each CPU rack).
BUS.PNC_ADD The PNC address is the input reference that the PROFINET
controller utilizes to return its status and diagnostic information. It
is recommended that the reference should be placed in the upper
segment of the discrete input references (%I16465 and above).
Genius Communication Gateway Modules
Figure 17: GCG Assignments – Bus A
BUS.GCG_A.PRI_NUM The PROFINET Device Number for the Primary PLC Gateway module
attached to Bus A.
BUS.GCG_A.SEC_NUM The PROFINET Device Number for the Secondary PLC Gateway
module attached to Bus A.
BUS.GCG_A.PSDA The PROFINET Status/Diagnostic bits for the Gateway module
attached to Bus A.
BUS.GCG_A.GSDA The Genius Device Status bits for the Gateway module attached to
Bus A.
If using an embedded PROFINET Controller in a CPE400, use slot 0 here. If using an embedded PROFINET Controller in a CPE330, use the
slot number location of the CPU itself.
