Introduction to PROFINET IO

PROFINET IO is a fieldbus protocol that enables communication between programmable controllers and
distributed field devices on an Ethernet network. The protocol classifies devices into IO-Controllers, IO-
Supervisors, and IO-Devices, which have a specific collection of services.
PROFINET IO uses three different communication channels to exchange data. The standard UDP/IP and TCP/IP
channel is used for parameterization and configuration of devices and for acyclic operations. The Real Time (RT)
channel is used for cyclic data transfer and alarms. The third channel, Isochronous Real Time (IRT) channel, is
used e.g. in motion control applications (not implemented in the JOHB-SMP3).
PROFINET IO devices are structured in slots and sub-slots, which can contain modules and sub-modules
correspondingly. Device specific data is represented in slot 0, module and sub-module specific data is in
subsequent slots and sub-slots.
One of the benefits of PROFINET IO is the diagnostics and alarm mechanism. Every module and sub-module
provide alarm data to the IO-Controller using the cyclic channel. Diagnostic data can be read non-cyclically from
the device by using record data.
Properties and services of a PROFINET IO device are described in a GSD file that is written in General Station
Description Markup Language (GSDML). GSD file describes the device specific modules and the method of
assigning modules and sub-modules to predefined slots and sub-slots.
Information about how to obtain the GSDML file is contained in

PROFINET IO in the JOHB-SMP3

The decision to use either the Yaskawa P-Drive control and status words or the Yaskawa-specific control and
status words is done in the hardware configuration tool (customer supplied). The default value is the Yaskawa-
specific format.
The JOHB-SMP3 uses slots 0 and 1. Slot 0 does not have any sub-slots and the attached DAP module represents
the device. Other functional modules and sub-modules described in the GSD file can be assigned to slot 1 and its
sub-slots.
• Slot 0 = Device access point (DAP)
• Slot 1, sub-slot 1 = One of the following:
– Standard Telegram 1
– Standard Telegram 1 with 5 configurable inputs and outputs
– 40-Byte IO with 5 configurable inputs and outputs
– Standard Telegram 1 with 10 configurable inputs and outputs
– Gateway Module
The services provided by the JOHB-SMP3 option can be defined by using the hardware configuration tool
(customer-supplied) or by using the F7-23 to F7-42 parameters in the drive. For services that are defined using the
hardware configuration tool, the associated drive parameter (F7-23 to F7-42) will be ignored. To define the
services using the F7-23 to F7-42 parameters, leave the defined services in the hardware configuration tool at a
value of 0.
If all F7-xx parameters are set to 0, the value from the configuration tool will be used.
The JOHB-SMP3 option provides the following services:
• Cyclic messaging in Yaskawa P-Drive or Yaskawa-specific mode
• Acyclic parameter access mechanism
• Identification & Maintenance functions (I&M0)
• Yaskawa P-Drive parameters
• Diagnostic and alarm mechanism
• Fault buffer mechanism

PROFINET Configuration Parameters

PROFINET Configuration Parameters are set through the hardware (PLC) configuration tool. They define the
behaviors, features, and some of the data exchanged by the JOHB-SMP3 on the PROFINET network.
