I am trying to get a micrologix 1500 to comunicate with a panewiew 300 micro using two AIC+'s. In linx i can only see one either the plc or the panelview depneding on which aic i plug my computer into. it only sees the one im pluged into and not the other. the two aic's are linked through the DH485 the plc in connected RS232 in one aic and the panelwiew is conected RS232 mini din on the other aic. any ideas what im doing wrong.
