Output 1: OR-link of evaluation cases 1 and 2
In the example above, output 1 of the lower LMS5xx is connected to input 1 of the
upper LMS5xx. A breach of the evaluation field is thus reported to the input of the
upper LMS5xx. In its evaluation case 2, this LMS5xx links the input to output 1. At the
same time, evaluation case 1 affects the upper LMS5xx and its output 1. By OR-linking
the two results, evaluation field breaches are reported on both LMS5xx units at output
1 of the upper LMS5xx.

Data interfaces
The device has different data interfaces for configuration and the transmission of
measured values.
NOTE
•
It is only possible to output all measured values of a scan in real time using the
Ethernet interface.
•
The data transmission rate of the RS-232 / RS-422 interfaces is limited to
500 kBd. Therefore these interfaces are not suitable for transmitting scan data
in real time.
Ethernet interface
The Ethernet interface has a data transmission rate of 10/100 Mbit/s. The interface is
a TCP/IP interface supporting full duplex and half duplex.
