Node Design; Grouping Of As-Interface Master Modules - WAGO -I/O-SYSTEM 750 Series Manual

2.1.2 Node Design

2.1.2.1

Grouping of AS-Interface Master Modules

Note
A maximum of three AS-Interface master modules can be incorporated
into one fieldbus node!
A single AS-Interface master module 750-655 can be placed at any position in
the node. However, if two or three modules are to be placed in direct vicinity
to each other in one node, they must be placed at the end of the node since in
that case power for the field supply should not be derived from the power
jumper contacts of the AS-Interface master modules. Also, the power for the
AS-Interface module must not be supplied via the CAGE CLAMP®
connections of the modules but must be fed in either between AS-Interface
master module and the slaves or between the slaves.
