Issue
This resolution clarifies the minimum hot fixes to be installed in Unity Pro v11.0 that guarantee a correct value of the variables from the PRM.

Product Line
EcoStruxure Control Expert, M580, PRM (TCSEGPA23F14F)

Environment
Unity Pro v11.0, BMEP581020 v2.50, PRM

Resolution
The PROFIBUS Remote Master (PRM) is a Profibus gateway that can also be used with M580 and the variables of the slaves are populated by a Device Derived Data Type. So, you need to install the hot fixes below to have a right order of bytes on Device DDT variables of the module and also when you connect the PRM to the BMENOC0301/0311/0321, modify the subnet mask or gateway address in the DHCP server:

• UnityPro_V110_HF0312464R_P-V81-M580 PRM data in DDT are mixed
• UnityPro_V110_HF0325873R DTM BMENOC doesn't transmit configuration to DTM PRM
