2.2.2 Using the SMP Gateway as a Protocol Translator
As we saw in the last section, the SMP Gateway is transparent when the master and slave
protocols are the same. When you configure different master and slave protocols, the
SMP Gateway becomes a protocol translator.
Since you can independently configure the communications links for the master and slave
components, you can easily use the SMP Gateway to integrate legacy serial devices in a modern
network environment. Similarly, you can connect modern IEDs to a legacy control center.
