Configuration

This chapter describes how to adapt the function and performance of this product to suit specific
applications. Because multiple devices are connected to Fieldbus, it is important to carefully
consider the device requirements and settings when configuring the system. Specifically, the
following steps must be taken.

(1) Network design

Determine the devices to be connected to Fieldbus and check the capacity of the power supply.
(2) Network definition
Determine the PD tag and node addresses for all devices.
(3) Definition of combining function blocks
Determine how function blocks are combined.
(4) Setting tags and addresses
Set the PD Tag and node addresses for each device.
(5) Communication setting
Set the link between communication parameters and function blocks.
(6) VFD parameter configuration
Set the parameter for function block VFD.
The following section describes each step of the procedures in this order. The use of a dedicated
configuration tool significantly simplifies the procedures below. This chapter explains procedures
that enable the user to configure even hosts that have relatively simple functions. Refer to
Appendix 4 when the device is used as Link Master.
4.1 Network Design
Power supply:
z „
Fieldbus requires a dedicated power supply. It is recommended that current capacity be well
over the total value of the maximum current consumed by all devices (including the host).
Conventional DC current of 4 - 20 mA cannot be used as is.
Terminator:
z „
Fieldbus requires two dedicated terminators. Refer to the supplier for details of terminators
that are attached to the host.
Field device:
z „
Connects the field devices necessary for instrumentation. This product has passed the
interoperability test conducted by the FieldComm Group. In order to smoothly start Fieldbus,
it is recommended that the devices used satisfy the requirements of the above test.
Host:
z „
Used for access to field devices and advanced control. At least one device with the bus
control function is necessary.
