Flag Area

MODBUS can also exchange data and fieldbus variables with the PLC via the
flag area. Caution is urged, however, when using data and/or variables in this area
that is accessed by both MODBUS and the PLC. This "conflicting" access is not
protected from either side and could result in data inconsistency.

Figure 106: Flag Area

The figure shows the maximum addressable flag area with a size of 104 kB.
The actual addressable flag area depends on the current memory arrangement in
the target system settings in CODESYS.
The default setting is 24 kB.
