Technical manual
Serial and LON communication module (SLM)
Introduction
The Serial and LON communication module (SLM) is used for SPA, IEC
60870-5-103, DNP3 and LON communication. SLM has two optical
communication ports for plastic/plastic, plastic/glass or glass/glass fibre cables.
One port is used for serial communication (SPA, IEC 60870-5-103 or DNP3 port)
and the other port is used for LON communication.
Design
SLM is a PMC card and it is factory mounted as a mezzanine card on the first
Analog digital conversion module (ADM). Three variants of SLM are available
with different combinations of optical fiber connectors, see figure 385. The plastic
fiber connectors are of snap-in type and the glass fiber connectors are of ST type.
