All commands can be transmitted independent from each other, i.e. all can be
send at the same time. However, their effects are not independent, as for
example sending Freeze and Unfreeze at the same time results in an
Unfreeze command at the slaves.
Specific groups to send the Global-Control command to, can be defined by
selecting the appropriate checkbox. Selecting the All Slaves checkbox will
disable the individual checkboxes, and result in a Global-Control command to
all slave devices.
In order to transmit the Global-Control, press the Transmit button. The com-
mand will be transmitted only once. Both the Global-Control command con-
tents, group select and the transmit command are transferred to the Unit
through its CIO words (see section 4-2-1 Software Switches 1 (Word n) and
section 4-2-2 Global-Control Message (Word n+2)).
from the PLC Program to write to the same software switches. Care should be
taken to avoid these situations.
The PROFIBUS Master DTM uses CX-Server to connect to the Unit for both
downloading a configuration as well as monitoring the Master Unit. To setup
the communication to the Unit, perform the following procedure.
1. Open the Master DTM Configuration Interface, Device Setup tab (see sec-
tion 3-3-1 Configuration User Interface).
2. Select the Unit Number. It must match the unit number set on the PROFI-
BUS Master Unit, through the rotary switch on the front.
3. Select the Configure button to start CX-Server.
Up on pressing the Configure button, CX-Server is launched and displays the
CX-Server User Interface as shown below.
In order to configure CX-Server for communication with the Unit, perform the
following procedure.
1. Select the type of PLC to which the Unit is attached, from the Device Type
drop down selection box.
