5.1.3 Device identification
Each PROFINET IO-Device possesses a device identification. It consists of a firm
identification, the Vendor-ID, and a manufacturer-specific part, the Device-ID. The
Vendor-ID is assigned by the PNO. For TR-Electronic the Vendor-ID contains the
value 0x0153, in case of the series 75 and 115 the Device-ID has the value 0x0401
and in case of series 88 the Device-ID has the value 0x0403.
When the system boots up the projected device identification is examined. In this way
errors in the project engineering can be recognized.
5.1.4 Distribution of IP addresses
Parameter
Default value
Description
MAC Address
-
By default in the delivery state the measuring system has saved his
MAC-Address
which is printed on the connection hood of the device,
e.g. “00-03-12-04-00-60”. The MAC-Address is not changeable.
Device type
Series 75 / 115:
TR CD_75_-EPN
Series 88:
TR AD_88_-EPN
The name for the device type is
- Series 75 / 115: “TR CD_75_-EPN”
- Series 88: “TR AD_88_-EPN”
and is allocated by TR-Electronic. The Device type is not
changeable.
Device name
-
Before an IO-Device can be controlled by an IO-Controller, it must
have a
Device name
, because the IP-Address is assigned directly
to the Device name. If necessary when the system boots up the IO-
Controller distributes the IP-addresses to the IO-Devices according to
their device names. This procedure has the advantage that names
can be handled more simply than complex IP-Addresses.
Assigning a device name for a concrete IO-Device is to compare with
the adjusting of the PROFIBUS address in case of a DP-slave.
In the delivery state as well as after a system boot up the measuring
system has not saved a device name. Only after assignment of a
device name with the engineering tool the measuring system for an
IO-Controller is addressable, e. g. for the transmission of the project
engineering data (e.g. the IP-Address) when the system boots up or
for the user data exchange in the cyclic operation.
The name assignment is executed by the engineering tool before the
beginning of operation. In case of PROFINET IO-Field devices the
standard DCP-Protocol is used.
IP Address
0.0.0.0
In the delivery state as well as after a system boot up the measuring
system has not saved an IP-Address.
Subnet mask
0.0.0.0
In the delivery state as well as after a system boot up the measuring
system has not saved a Subnet mask.
Proceeding at the distribution of Device names and Addresses
in case of an IO-Device
● Define Device name, IP-Address and Subnet mask. Depending on configuration
this process can be executed also automatically by the IO-Controller.
● Device name is assigned to an IO-Device (MAC-Address)
–
Transmit Device name to the device
● Load projection into the IO-Controller
● When the system boots up the IO-Controller distributes the IP-Addresses to the
Device names. The distribution of the IP-Address also can be switched off, in this
case the existing IP-Address in the IO-Device is used.
