OMRON PART 1: CX-Programmer
CX-Programmer_Page (xxxi)
• Changing the PVs for DM/EM Areas in Bit Units
Previous version (Ver. 3.3) New version (Ver. 4.0)
PVs for DM/EM Area data
could not be changed in bit
units.
While online, when the binary display is selected in the
Set New Value dialog that is displayed when the
address in the watch window is clicked, the DM/EM
Area data can be changed into PVs in bit units.
Prevention of Leaving Set Forced Set/Reset Status
• Checking the Forced Set/Reset Status when Changing from Online to Offline
Previous version (Ver. 3.3) New version (Ver. 4.0)
After forced setting/resetting of
a bit online, the forced set/reset
status remained unchanged
when online status was
changed to offline status.
After forced setting/resetting of a bit online, a dialog
box is displayed when status returns to offline to allow
the forced set/reset status of addresses to be
displayed. The forced set/reset status can also be
cancelled.
Enable this function by selecting Tools − Options and
then selecting Check forced status after online
connection in the PLCs Tab Page (the default setting
is OFF: no confirmation).
This function prevents going offline unprepared when
the CPU Unit is still in forced set/reset status.
Improvements to Printing Functions
• Printing Ladder Programs as Shown on Screen
Previous version (Ver. 3.3) New version (Ver. 4.0)
Ladder programs could not be
printed as they were shown
on the screen.
Sections of the ladder program can be printed
separately as they are shown on the screen.
Select to print the ladder screen in the page setting.
The ladder screen can be printed as it is shown on the
ladder screen.
The program can also be printed at a smaller size
(Reduced size), or a larger size (Enlarged size), instead
of the standard size (Normal size).
Improvements to Multi-interlock Display Functions
• Displaying the Multi-interlock Status (CS/CJ-series CPU Unit Ver. 2.0 or Later)
Previous version (Ver. 3.3) New version (Ver. 4.0)
Interlock instructions allowing
nesting were not supported.
If the interlock instruction that allows nesting (multi
interlock instruction) is used with a CS/CJ-series PLC
Ver. 2.0 or later when performing online monitoring, the
display will show which instruction segment is presently
in interlock status using a tree-structure at the left of the
ladder screen (multi-interlock map). By double-clicking
the instruction in the multi-interlock map, the ladder
view will jump to the display of the applicable rung.
