Creating and Editing Master Parameters

•
Information for the Slaves involved in remote I/O communications with the
Master must be input separately for each Slave.
•
After creating the parameters, they must be saved as a Master parameter file
and later set in (written to) the Master in the actual network.
Acquire Slave information by reading the actual network’s device list and create
the Master parameters with that Slave information. This method can be used just
after the network has been assembled, so the actual network exists but there are
no Master parameters at all.
The main features of this method are outlined below:
•
It must be possible to connect to the network. (If a direct connection isn’t pos-
sible, a copy of the network configuration file can be used.)
•
The “Create Master Parameters” or “Master Parameter Wizard” command can
be used to create the parameters.
•
If the “Master Parameter Wizard” command is used, I/O can be allocated auto-
matically. I/O words are allocated in node-address order with automatic alloca-
tion, but the allocation can be changed later by editing the Master parameters.
•
Since the Slave information is taken from the actual network, very little time is
needed to register Slaves for remote I/O communications. (It is also possible to
add or remove Slaves as needed.)
•
After creating the parameters, they must be saved as a Master parameter file
and later set in (written to) the Master in the actual network.
Editing Existing Parameters
Edit the Master parameters in a network configuration file saved from a device
list of the actual network. This method can be used to edit Master parameters
created when it isn’t possible to connect directly to the network or to change the
parameters for a planned change in the network configuration.
The main features of this method are outlined below:
•
The Master parameters can be edited if there is a network configuration file
with Master parameters, even if it isn’t possible to connect directly to the net-
work.
•
Use the “Edit Master Parameters” command for the desired Master.
•
Since the existing Master parameters are used, minor changes can be made
quickly. (Slaves can also be added or removed as necessary.)
•
If the Configurator is online, the changes can be written to the Master immedi-
ately. No time is required to read and save a Master parameter file. (The Mas-
ter parameters can also be included in the network configuration file.)
Edit the Master parameters that are in the actual network’s device list. This
method can be used when it is possible to connect directly to the network and
changes are needed in the Master parameters.
The main features of this method are outlined below:

It must be possible to connect directly to the network.
•
Use the “Edit Master Parameters” command for the desired Master.
•
