18.5.4.1 Communication ports
The serial communication module (SLM) is a mezzanine module placed on the
numeric processing module (NUM). It is used for LON, SPA, IEC 60870-5-103 and
DNP communication.
There are two types of IO connectors: snap-in connector for plastic fibre cables and
ST/bayonet connector for glass fibre cables. The SLM can be equipped with either
type or connector or with a combination of both types of connectors. This is identified
with a tag.
Connect the incoming optical fibre to the RX receiver input, and the outgoing optical
fibre to the TX transmitter output. Pay special attention to instructions concerning
handling and connection of fibre cables.
For setting the transfer rate (baud rate) and slave number, please refer to the
Application manual and Commissioning manual respectively.
