4 Creating Project Files—PLC to Devices
4 Creating Project Files—PLC to
Devices
This chapter covers configuration of the DTU3005 for PLC
communications with Siemens devices. Once you have created a PLC to Devices project (see Chapter 3), follow the
directions in this chapter to configure the project file. Then
see Chapter 7 for directions on downloading the project to
the DTU3005. See also Appendix D for wiring diagr ams for
your particular PLC, as required.
4.1 Application Description
The PLC to Devices application allows a PLC to control and
monitor up to 32 SEAbus devices or Siemens protective
relays. In this application, the DTU3005B initiates all communications with both the PLC and the Siemens devices.
The DTU3005B uses an internal transfer table to transfer
data to the PLC. The transfer table contains a block of
selected real-time data parameters obtained from a device.
The DTU3005B unit acts as a master to the PLC, and continuously transfers the table data to the selected block of
registers on the PLC. A delay option is provided for each
device’s table entry to prevent unnecessarily slowing down
the scan time of the PLC as well as to give some device
data transfers higher priority than others.
No ladder logic is required on the PLC to use the basic feature of this application, which allows a limited amount of
information to be transferred between the PLC and the
devices. Ladder logic programming is required to use the
command block function. The command block is used to
send commands to the devices, such as operating or
releasing relays, or resetting energy counters. See
Section 4.11 for information on configuring this feature on
the DTU3005B. The format of the command registers for
each device are described in Appendix E.
The DTU3005B can automatically update diagnostic information in the PLC. It allows the PLC to determine when a
device is not communicating. See Section 4.10 for information on enabling and configuring this feature. The format and
content of the diagnostic registers are described in detail in
Appendix F.
4.2 Configuring the Project File
Once you have created or opened the project file, select
Edit from the main menu to display the following menu
items:
• Port 1 (PLC)—allows you to select the model and configure the communications settings for the PLC connected to port 1.
• Port 2 (Devices)—allows you to co nfigure communications settings for SEAbus devices or Siemens Protective relays connected to port 2.
12 Siemens Energy & Automation, Inc.
• Port 3 (Passthrough)—allows you to select whether
port 3 is used as a passthrough to the devices or the
PLC.
• Diagnostics—allows you to indicate if you want the
DTU3005 to write communications diagnostic information to the PLC.
4 Creating Project Files—PLC to Devices
• Device Command Registers—allows you to indicate
which PLC registers will be u sed for dev ice co mmands.
• 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 communicating 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.
4.3 PLC Setup—P ort 1
You must have a PLC to Devices project file open to configure port 1 using the instructions in this section. Select Port
1 (PLC) from the Edit menu, and the Port 1 PLC Configura-
tion screen appears.
