3.1.6.6 PLC checksum calculation

When working in offline mode, the PLC Checksum calculation option calculates the CRC of the PLC equations and Relay
configuration section for the open *.650 file. When a *.650 file is uploaded to the relay, the calculated PLC Checksum and
the actual value of the PLC Checksum read from the relay (Actual values > Status > System Info) must match.
In order to calculate this checksum, the following sections of the * .650 file are considered:
• All equations compiled in the file and located in EnerVista 650 Setup Setpoint > Logic configuration
• Configuration available in the file and located in EnerVista 650 Setup Setpoint > Relay configuration, excluding:
– HMI tab configuration
– All configured text
– Opening and closing time in the Switchgear section
