4.9 Communications
WARNING! –
DO NOT ATTEMPT TO CHANGE SETTINGS OR OTHERWISE OPERATE THE DRYER
REMOTELY WITHOUT A FIRM UNDERSTANDING OF DRYER OPERATION. IMPROPER SETTINGS
OR CONTROL MAY RESULT IN DAMAGE TO THE DRYER.
THE MODBUS PORT AND MODBUS REGISTERS ARE NOT PROTECTED FROM UNAUTHORIZED
ACCESS ON THE NETWORK. ANY SECURITY CONCERNS SHOULD BE ADDRESSED BEFORE
CONNECTING THE ETHERNET PORT TO THE NETWORK.
The display panel includes an Ethernet and a Serial port which can be used for Modbus communications.
The Ethernet port can be used to access Modbus/TCP registers, as well as, VNC servers across multiple dryers.
The Serial port can access Modbus RTU registers using either RS232 or RS422/485 hardware protocol.
VNC Server
The internal VNC server runs in the back ground by default. Any VNC Client may be used to access the dryer’s VNC
server via port 5900. Excessive network traffic or network interference may cause the VNC server to intermittently
shut down. Rebooting the display panel via the Service menu or via Modbus register 40101 will restore the VNC
Server after reboot.
Serial Modbus RTU Port
The serial port is located along the bottom edge of the HMI. This port supports full RS232, RS422, and RS485 hard-
ware protocols. This port is NOT isolated. Proper cabling and isolation techniques are required to prevent electrical
noise from entering the system through this port. Contact your local electrical parts distributer for assistance.
Other Serial Protocols
In order to connect the dryer to serial networks that use other protocols (such as ProfiBus or Device net) a gateway
device will need to be connected to convert the Modbus RTU protocol to the desired protocol. Consult your systems
integrator for assistance in specifying the correct device.
Ethernet
Proper cabling and isolation techniques are required to prevent electrical noise from entering the system through this
port. Contact your local electrical parts distributer for assistance.
The Ethernet port is pre-configured to acquire its network IP address and configuration from the network’s DHCP
server. Use the following procedure to set a static IP address.
