DH485 Protocol


Thread Starter


The DH485 protocol is free now, correct? Does anyone know where to find this protocol, I couldn't find it on AB's website.
I need this protocol too. Please to anyone who may get it, send me mail with them . Thanks.
I'm student of SCADA/HMI systems on faculty of mechanical engineering in czech republic, and I write a thesis to communication with PLC micrologix 1000 and SCADA systems.

Ok. Thanks, I was afraid of that. Do you know if the same rule applies to the SLC 5/05 Ethernet? I know that the Ethernet Ip is open through the ODVA.org.
