Wizard - Modbus RTU Master
This wizard can be used to create a Modbus-RTU-based network configuration based on certain infor-
mation about the sub-network. The on-line help system explains each configuration step in detail.
• Important Notes:
Many OEM devices do not fully comply with the Modbus standard. For example, they may
implement a variation of this standard or be limited to the use of specific Modbus commands
other than the ones used by this wizard. In all cases, the user should consult the documentation
of the devices that shall be used on the sub-network for information about their serial commu-
nication requirements, and if necessary contact the manufacturer of the device to obtain further
information about the serial communication protocol.
In the event that the wizard doesn’t handle a particular Modbus command required by a device,
it is possible to specify this command manually as a transaction in the ABC Config Tool.
Using this wizard involves the following steps:
Step 1: Communicator Type
Select ‘Modbus RTU’.
Click ‘Next’ to continue.
Tip:
It is possible to return to a previous
menu at any time without losing any set-
tings by clicking ‘Previous’.
Step 2: Physical Settings
Select the physical properties of the sub
network.
Click ‘Next’ to continue.
