Siemens PXX-L11, PXX-L12 – Extension modules CM1N9282en_06
Building Technologies 2015-12-23
The PXX-Lxx extension modules support Extended Command Set (ECS) to EIA-
709.1-B protocol. If a L
ONWORKS node is written with an ECS command (e.g.
installation by NL220), several legacy commands will be refused by the module
from this moment on. A module configured in this manner will only allow restricted
communication with older tools that do not support ECS (e.g. the diagnostic tool
NLUtil).
Mechanical design
The compact construction enables the extension module to be used in highly
confined spaces.
