PLX82-EIP-PNC ♦ Communication Gateway Configuring the PROFINET Controller
EtherNet/IP™ Server to PROFINET Controller User Manual

Parameter Description
Start of bus
communication Automatically by device or Controlled by application .
If Automatically by device, the PNC controller device starts with the data
exchange on the bus after initialization has ended.
If Controlled by application, the application program must activate data exchange
on the bus.
The default is typically set to
Controlled by application .
Application monitoring
Watchdog time is set per station in the Stations Timing window. This field
displays the watchdog time in milliseconds. The Watchdog time determines the
time in which the device watchdog must be re-triggered from the application
program while the application program monitoring is activated.
When the watchdog time value is equal to 0, the watchdog is deactivated and the
application program monitoring is also deactivated.
Watchdog time Range of Value/Default Value
Permissible range of values 20 to 65535 ms
Default 1000 ms
Deactivated 0 ms
Process image
storage format Big Endian (Most Significant Byte first)
Little Endian (Least Significant Byte first)
Port Settings Displays or selects Port 1 settings. This is used if Fast Start Up (FSU) is selected
for PROFINET devices that use FSU connection to establish a cyclic data
exchange.
If FSU is check on a port, you must select
100BASETXFD . Otherwise, select
AUTO .
IO State Information Input Provider - Disabled, Bit, Byte
Output Provider - Disabled, Bit, Byte
Allows you to configure the PROFINET Input/Output Object Provider State
(IOPS). This allows the PNC application program to detect whether data received
from a slave is valid or not and vice versa.
Disabled - The PROFINET controller application cannot detect whether the data
received from the PROFINET slaves are valid or declare its output data sent to
the slaves are valid or invalid.
Bit - IOPS is handled as a bit list. Each sub-module description is represented by
a single bit. If set to 1, the data is valid. If set to 0, the data is invalid. Sub-
modules with input and output data simultaneously have IOPS in input and output
directions.
Byte - In the dual-port memory (DPM) of the PNC, IOPS is handled as a byte
array. Each sub-module description is represented as a byte. If the byte is set to
0x80, the data is valid. Otherwise, the data is considered invalid.
In this mode, the entire IOPS byte is directly copied from/to the cyclic frame,
providing the PNC's application program the possibility of accessing all bits of
IOPS. Typically, only the first bit of the IOPS byte states whether the data is valid
or invalid.
Module Alignment Byte boundaries
2 Byte boundaries
Module Alignment defines the addressing mode of the process data image. The
addresses (offsets) of the process data are always interpreted as byte addresses.
The Module Alignment then defines the addressing mode.
