5.2.1 PROFINET Scanner Status and Control Data
The RX3i PNS001 provides 32 bits of input status data and receives 32 bits of output control data.
The application program in the control system in which the PROFINET Controller is resident should contain
code that will monitor the input status bits from the PNS module.
5.2.1.1 Output Control Bits
The 32 bits of control output assigned to the PNS module are reserved for future use.
5.2.1.2 Input Status Bits
The 32 bits of input status assigned to the PNS module provide information about the scanner. All status
bits are active high. Bit 1 is the least significant bit.
