Setting parameters
To activate network operation of the MA 30/31, it may be necessary to set
several parameters. For best results, use the CONFIG 3.0 configuration soft-
ware for PCs, a program developed expressly for this purpose. This allows
the use of a fixed data format to adjust via the service interface of the
MA 30/31 the master and all slaves in the network without interrupting the
connection to the host computer.
4.1
Setting the last slave address
Last slave address
The MA 30/31 searches for the selected number of slaves in the network
when the operating voltage is switched on. The number of the slave with the
highest address is called the
last slave address
. This information must be
passed on to the MA 30/31. There are two possibilities:
•
Setting the
last slave address
with the rotary switch on the MA 30/31
•
Setting the
last slave address
via software setup
(rotary switch in position "0")
A hardware address has a higher priority than a software address, i.e. the
software address is only evaluated when the rotary switch is in position "0".
On the other hand, a software address does not need to be set if a hardware
address >0 has been configured.
It is not necessary to call up the setup when adding one or more subscribers
to the network; the rotary switch can simply be turned to the appropriate posi-
tion. The next time the operating voltage is switched on, the new slave(s) will
automatically be added to the network.
If you would like to make the setting using the software setup, you must put
the MA 30/31 into operation and configure it from a PC.
4.2
Setting the host interface
Host interface
Prior to the initial commissioning of the host interface, it must be set to the
parameters of the host computer/PLC.
To do this, use the service interface of the MA 30/31 and switch to "service
network" (see chapter 2.6 "Service mode").
Using the CONFIG 3.0 configuration software, you can make the changes to
the host interface off-line, and then download them to the MA 30/31.
