Here you will find a technical description of how to configure the KUNBUS gateway Ethernet/IP with CODESYS.
System overview
these devices have been used for this application note
KUNBUS Gateway Ethernet/IP
Revolution Pi Core 3 (3+, S) or Connect (+, S)
please connect your devices as shown in the below
Preparation
Please follow the instructions of the checklists:
follow the checklist below
install Packages on CODESYS IDE
Install runtime on the Revolution Pi Connect
Optional: install CODESYS license
#sudo nano /etc/dhcpcd.conf
# Example static IP configuration:
interface eth1
static ip_address=192.168.1.100/24
/etc/dhcpcd.conf shown in line 50-52
# A sample configuration for dhcpcd.
# See dhcpcd.conf(5) for details.
# Allow users of this group to interact with dhcpcd via the control socket.
#controlgroup wheel
# Inform the DHCP server of our hostname for DDNS.
hostname
# Use the hardware address of the interface for the Client ID.
clientid
# or
# Use the same DUID + IAID as set in DHCPv6 for DHCPv4 ClientID as per RFC4361.
# Some non-RFC compliant DHCP servers do not reply with this set.
# In this case, comment out duid and enable clientid above.
#duid
# Persist interface configuration when dhcpcd exits.
persistent
# Rapid commit support.
# Safe to enable by default because it requires the equivalent option set
# on the server to actually work.
option rapid_commit
# A list of options to request from the DHCP server.
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
# Respect the network MTU. This is applied to DHCP routes.
option interface_mtu
# Most distributions have NTP support.
#option ntp_servers
# A ServerID is required by RFC2131.
require dhcp_server_identifier
# Generate SLAAC address using the Hardware Address of the interface
#slaac hwaddr
# OR generate Stable Private IPv6 Addresses based from the DUID
slaac private
# Example static IP configuration:
interface eth0
static ip_address=192.168.168.70/24
#static ip6_address=fd51:42f8:caae:d92e::ff/64
#static routers=192.168.0.1
#static domain_name_servers=192.168.0.1 8.8.8.8 fd51:42f8:caae:d92e::1
# Example static IP configuration:
interface eth1
static ip_address=192.168.1.100/24
# It is possible to fall back to a static IP if DHCP fails:
# define static profile
#profile static_eth0
#static ip_address=192.168.1.23/24
#static routers=192.168.1.1
#static domain_name_servers=192.168.1.1
# fallback to static profile on eth0
#interface eth0
#fallback static_eth0
# Prioritize wlan0 routes over eth0 routes.
interface wlan0
