Modbus TCP
Establishing a connection via TCP/IP to the device is only possible if the device is
equipped with an Ethernet Interface (RJ45).
Contact your IT administrator in order to establish the network connection.
Part 1: Setting the TCP/IP Parameters
Call up [Device Para / TCP/IP / TCP/IP config] at the HMI (panel) and set the following
parameters:
• TCP/IP address;
• Subnet mask; and
• Gateway.
Part 2: Configuration of the Devices
Call up »Device parameter/Modbus« and set the following communication parameters.
• Setting a unit identifier is only necessary if a TCP network should be coupled to a
RTU network.
• If a different port than the default port 502 should be used, please proceed as
follows:
• Choose "Private" within the TCP-Port-Configuration.
• Set the port number.
• Set the maximum acceptable time out for "no communication". If this time has
expired without any communication, the device concludes a failure has occurred
within the master system.
• Allow or disallow the blocking of SCADA commands.
Part 3: Hardware Connection
• There is a RJ45 interface at the rear side of the device for the hardware connection
to the control system.
• Establish the connection to the device by means of a proper Ethernet cable.
