Digital Inputs via the LSB Module, LSB Address 11 and 55
8.3.1
Functional Description
•
4 floating digital inputs per module
•
8 digital inputs possible (2 modules)
•
The digital inputs are activated manually using switches.
LSB modules are universally applicable output modules for DIN rail mounting. They are actu-
ated via the LSB. The module is addressed via a settable address (1 ... 99). The data bytes
convey whether data is required or commands are to be executed.
NOTICE
All outgoing lines from the LSB module must be screened. The screens must be applied to the
PE rail as short as possible.
NOTICE
The termination resistor (120
)
must
be installed and activated on the first and the last BUS
device.
Avoid transmission line!
