Delta RMC101 - Manual (Page 77)

Basic Topics 3.4
Using RMCWin 3-27
3.4.8 Using the Status Bits Window
The Status Bits window displays the bits of the Status words for each axis. It is constantly
updated as the bits change in the RMC.
To display the Status Bits window, do one of the following from the main window:
• On the Window menu, click Status Bits.
• Press CTRL+B.
Additionally, the Status Bits window can be displayed by using any of the methods of displaying a
Pop-up Editor.
3.4.9 Using the Command Log
Command Log Explained
When debugging problems with a system that is using the RMC, it is often difficult to determine
whether the problem is caused by an action of the RMC or the Programmable Controller (P/C).
To help with this problem, the Command Log is available. The Command Log holds the last 256
commands received through the communication module; commands sent by RMCWin or the
event step table are not displayed. Therefore, the Command Log can be used to determine which
commands were actually received by the RMC.
The "To PLC from Module" Section
This section is applicable only with PROFIBUS-DP in Compact Mode. Otherwise, the values will
be zero and grayed out. This section displays status information for each axis that is available to
the P/C. For each axis there are two pieces of information:
Status - This displays the Status word of the axis.
Data - The value of this field depends on the Status Area Request field of the last command sent
from the P/C on this axis. It can be equal to any of the Status Parameters.
The "From PLC to Module" Section
All communication types use this section. The most recent commands are at the top of the
Command Log. In addition, you will notice that the commands that changed from the previous
Command Log entry are colored red.
When using a Communication Digital I/O, the commands that are issued based on the digital
inputs will be recorded in the command log. Refer to the Communication Digital I/O section for
specifics on these commands.
For other communication modules, these fields represent the commands and command values
received from the P/C. In addition, if there are rising or falling edges on CPU or Sensor Digital I/O
inputs 0 used by the Input to Event table, 00045 commands (Start Events) will be issued to the
command log.
