Local Behind-level Expansion Address Description
After coupler module is power-on, it will scan local back-level expansion interface,
and it will assign one expansion address for each scanned expansion submodule.
→
Expansion example:
Like, the local back-level interface of ECAT communication module (ZMIO310-ECAT)
connects to 3 input modules (ZMIO310-16DI), 2 output modules (ZMIO310-16DO /
ZMIO310-16DOP), 1 AD module (ZMIO310-4AD) and 1 DA module (ZMIO310-4DA) in turn.
ECAT communication module starts to scan and assigns address when it is power-
on. The submodule address is assigned starting from 0, then assign the address
according to the connection sequence, that is, the expansion address of the first input
module is 0, the expand address of DA module is 6.
