Block Summary
Thus from a block data-sharing point of view, each block will contain data as shown in
the following list. Any number of ECOM100s (or Do-more's) on the network can listen
(subscribe) to any of this data. The important thing to remember is that only one PLC can
write (publish) a particular block; otherwise, there would be a conflict. Thus there can be any
number of subscribers, but only 16 publishers per Peerlink data-sharing network.
