Implicit EtherNet/IP messages contain 0 for attributes of some analog modules

Applies To:

Versions Affected:

Versions affected: PAC firmware R9.4a through R9.5e
Problem is fixed in version: PAC firmware R9.5f

Resolved In Version:

Problem is fixed in version: PAC firmware R9.5f

Symptoms:

If configuration information for an EtherNet/IP assembly is stored in flash memory, after power-up, attribute data for some analog modules may be set to 0 (zero) in Target-to-Originator (T2O) implicit messages.

Workaround:

Do not store the assembly configuration to flash. Instead, use PAC Manager to clear flash memory of the brain or controller, and then, after power up, use EtherNet/IP Configurator to download the EtherNet OTG file.

Resolution:
