Not that this addresses the rant, but you could add your analog channels via this product. The protocol master doesn’t have to be in the same panel (but it does need to be in a safe environment (no water, excessive or hazardous dust, etc…)). You also wouldn’t have to deal with Profibus, you just simply message to and from the protocol master as if it were another AB PLC (SLC, MicroLogix).
