Unconnected (UCMM)
messaging relies on shared resources to transfer
data to the PLC. This could result in message timeouts if there are a lot of devices fighting for these
shared buffers. If you don’t want the RTA gateway to constantly keep the con
nection open to the
PLC but only maintain a connection when there is data needed to be transferred, then Unconnected
(UCMM) will work best if you are only writing to the PLC.
Connected
(Class 3 Explicit)
messaging
relies on reserved resources to transfer data to/from the PLC
. Connected (Class 3 Explicit)
messaging is recommended if you are reading and writing and always want to keep that connection
open to the PLC.
