4 Creating Project Files—PLC to Devices

•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.
