4.9Global Command Registers
This option allows you to specify global commands for all the devices specified in the Device List. It is available only for VDEW devices.
The Global Command Registers consist of six registers. These registers allow the PLC to transmit commands to all the devices in the Device List. To send a command, all the PLC needs to do is to place the command values into the appropriate PLC registers, which the DTU3005 unit reads and then processes.
4.10Device Diagnostic Registers
This option programs the DTU3005 to send communica- tions diagnostic information to a set of registers on the PLC. The information can be used to troubleshoot problems with the devices and the communications network.
The format and content of the diagnostic registers are described in detail in Appendix F.
1.To configure the device diagnostic registers, select Diagnostics from the Edit menu. The following screen displays:
2.To enable the sending of diagnostic information to the PLC, select the Do you want device diagnostics information sent to PLC? checkbox with the mouse or the spacebar. Then enter the starting register num- ber in the PLC Registers: field. The register block is 6
bytes long. Be sure that the registers you specified are not being used by other devices.
3.Press Shift+Tab, or click the left mouse button to high- light the File field and enter the file number. This
