Modbus,Profibus and Fieldbus are industrial standrad
protocols with which instruments are communicating each
other. A protocol is a set of rules that governs
communications within a network, defining everything from
how connections are made between devices to how the message
itself is formatted. They can be implemented through
software, hardware, or both.

Yokogawa CENTUMVP R6.09 unable to download to Engineering Station with ExaOPC R3.75 The issue is when I try to download the common project section to the Engineering Station (STN) from the HIS in System View, it is unable to connect. The error displayed is: WARNING: Could not connect to equalize destination. (7001) Retrying. Number of retries = 0/1 ERROR: LdXopsLoadMain: connect error 10060 ERROR: Processing terminated due to connection error. (7002) Equalization end with errors. STN0149 ---- ERROR = 2 WARNING = 1 ---- Background: >Updated the ExaOPC software on the STN from 3.60 to 3.75 >STN operating system is Windows Server 2008 R2 >HIS operating system is Windows Server 2016 Stanard Solutions attempted include: >Ensuring all IP addresses are correct and all networked devices can be pinged. >The ability to ping a device using its host name from another device ( from HIS) >Ensure both devices firewalls are disabled. >The antivirus installed on the STN is disabled. >Ensuring both devices are within the same workgroup. >Added both devices to each other's Host and LMHost files. >Running IT Security tool after changing any administrative settings.
