The Acyclic Connection/Abort status box contains the following information.

Area
Start Address
Length
1. If the selected PLC memory area, on to which the data must be mapped is
not supported by the PLC CPU, a warning message will be displayed upon
downloading the configuration.
2. If an invalid setting is made the Length value will change its colour to red,
indicating an invalid setting. In addition, a warning message will be dis-
played, upon saving the changes. Invalid settings are for example
• The start address and length definitions of the data block will cause it
to exceed the area in the PLC.
• The mapping overlaps with one or more of the I/O Areas (Output and/
or Input) mappings.

Note In the above figure, n is the start address of the memory locations, defined by
the Area and Start Address setting in the Acyclic Connection/Abort Status
Box.
Status Controlled
by
ON Unit If the bit corresponding to a slave device address is ON, it indicates that
the PROFIBUS Master Unit has established a PROFIBUS DP-V1 Class
2 type connection.
OFF Unit If the bit corresponding to a slave device address is OFF, it indicates
that there is no open PROFIBUS DP-V1 Class 2 type connection with
the specific slave device.
Selects the PLC memory area to which the Acyclic Con-
nection/Abort status bits will be mapped. Possible
options are (See Note):
• Not Used (Default setting, Start Address and Length
will be set to 0).
• CIO
• DM
• Work
• HR
• EM Bank 0 to 12 (Decimal)
In this field the user can enter the start address in the
PLC memory of the mapped data block.
The length value is a fixed number. The total number of
words is 16.
