Resolution
The DR (Sepam 1000 Americanized) commumicates with a protocol called PowerLogic (Sy-Max) and the Sepam 20, 40 & 80 uses Mod-Bus RTU , an Industry standard protocol developed by Modicon. These two relays cannot communicate on the same daisy chain. A device such as EGX, ethernet gateway, can interface the two protocols for a common host.
