Is there any TM172PDG28SI's ability for RS-485 Exchanging over custom protocol?
What I mean:
1) There is one device with rs-485 interface and custom protocol implementation in it. Packages is very primitive and parsable
2) So there is one PLC TM172PDG28SI with two free RS-485 interfaces
3) In PLC's IDE every RS-485 can be configured only for ModBus protocol.
4) IDE's functions also may working only with ModBus.
So, Is the ability for custom protocol exchanging over RS-485

Yes that is possible. Look in ESME HVAC for the sysUART function in Target blocks
with this function you could create a communication via Serial line.
