Monitoring Data - Omron CX-PROGRAMMER V9 - REV 12-2009 Operation Manual

OMRON
When an Online transfer to PLC operation is executed, the PLC Memory Component will read the TIM/CNT
mode setting from the PLC. If the TIM/CNT mode is set to BCD, then the command will be actioned only if the
current data type is also BCD. If the data type is not BCD, then a warning message will be displayed, and the
commend will be aborted.
If the TIM/CNT mode is set to Binary, the command will only be actioned if the current data type is Decimal or
Hexadecimal. If the current data is neither Decimal or Hexadecimal, then a warning message will be displayed,
and the command will be aborted.
When an Online Transfer from a PLC, Compare or Monitor operation is executed, the PLC Memory Component
will read the data from the PLC and display it in the currently selected data format. If the data can not be displayed
in the currently selected format, then an error message will be displayed.

Monitoring Data
