Overview

There are several tools to assist you in diagnosing problems with the Series 90-70 Ethernet Interface and the network.

HThe Ethernet Interface LEDs provide an immediate visual summary of the operational state of the Ethernet Interface.

HThe Series 90-70 PLC Fault Table provides a record of exceptions logged by the PLC, the Ethernet Interface, and other Series 90-70 modules. The PLC Fault Table may be accessed through the Logicmaster 90-70 Configurator or Programmer software.

Refer to the Series 90-70 Programmable Controller Reference Manual for more information.
