4.3 Synchronism of Transfer Data
Application software and the OD.RING module may simultaneously access the memory transfer
area because they asynchronously access that area. In these cases, note that synchronism of transfer
data as a memory transfer area block is lost.
For example, if an application reads the memory transfer area during update by the OD.RING
module of that area, the chronological sequence of the data contained is disrupted.
Application software and the OD.RING module, however, assure such sequence in each individual
word. Thus, analog data and counter values are transferred normally.
