IP67 Digital I/O Modules for PROFINET IO

SubslotNumber: 0x01

channelProperties.Speifier: 0x0002 (Disappears)

channelErrorType: 0x0002 (under voltage)
Note: If you do not apply +24 output voltage on
TBDEP-8YYP-D84 or TBDEP-4YYP-D8U (Full input configuration only) with
firmware version ≤1.32
, an alarm “power drop” will be sent to the PLC. The only way to clear this alarm is to
apply +24 output voltage.
Topology Discovery (LLDP)
LLDP (Link Layer Discovery Protocol) is a standard which provides a solution for the configuration issues
caused by expanding LANs. LLDP specifically defines a standard method for Ethernet network devices such as
switches, routers and wireless LAN access points to advertise information about themselves to other nodes
on the network and store the information they discover.
The HarshIO 300 ePN manages LLDP as a Sender and Receiver;

As a Sender; each Ethernet port of the integrated switch of the HarshIO module produces LLDP frame
to its neighbor devices with the following information:
o
MAC address
o
Ethernet port identification
o
PROFINET name
o
Material number (TBDEP-xxxx)
o
Description name

As a Receiver; each Ethernet port of the integrated switch of the HarshIO module consumes the LLDP
frame of the neighbor devices.
Note: LLDP is always active on the ePN module.
Easy Device Replacement
PROFINET optimizes the device replacement and first commissioning processes.
PROFINET devices are identified via a name that is assigned in the configuration. When replacing a defective
device, a new device (with the same commercial reference) can be recognized by the IO-Controller by means
of topology information and have a name automatically assigned to it.
An engineering tool is therefore not required when replacing devices. This mechanism can also be used
during the initial commissioning of a complete plant. Quick commissioning is thus especially possible for
series machines.
The HarshIO 300 ePN supports easy device replacement service (based on LLDP receiver protocol).
