• Device Command Registers—allows you to indicate

which PLC registers will be used for device commands.

• Device Defaults—allows you to set the default data

registers for more than one device of a certain type,

e.g., set the defaults for all 4720 power meters or all

S7-I/O units. The data registers can still be customized

for each device, as required. See Section 4.7.2 for

more information.

• Device List—allows you to indicate which SEAbus

devices or Siemens protective relays are connected to

port 2 and which PLC registers they are communicat-

ing with.

If the Device Protocol for port 2 is set to VDEW (see

Section 4.4), then two additional menu items are available:

Global Command Registers and Device Text to Values

Table. See Section 4.8 and Section 4.9 for instructions on

using these menu items.

You must have a PLC to Devices project file open to config-

ure port 1 using the instructions in this section. Select Port

tion screen appears.
