Connecting the PC to an Ethernet Module or Coprocessor

Prerequisites

For an Ethernet module or coprocessor update, follow these recommendations:

Make a minimal configuration with only the following equipment:
- CPU with embedded Ethernet module, or CPU and Ethernet module (140 NOE 771 •1, or 140 CRP 312 00).
- Power supply.
- Rack.
Only connect the following devices to the same Ethernet network:
- PC running OS Loader software.
- CPU with embedded Ethernet module, or 140 NOE 771 •1, or 140 CRP 312 00 module.
Configure the PAC system with an empty program containing only the IP address configuration.

The Ethernet module or coprocessor has to be on the same Ethernet network as the PC running OS Loader. The Ethernet module and PC need to have compatible IP address, subnet mask, and default gateway.
The CPU is in Stop mode.
The Ethernet module to update has no TCP traffic.

NOTE: The update procedure is a maintenance operation. It requires the CPU to be in STOP mode, disconnected from the systems and applications it affects, and no functional communication traffic occur between the CPU and the module.

Connection Mode

To perform the physical connection between the PC running OS Loader and the CPU or Ethernet communication module, you can use:

A crossover Ethernet cable directly between both equipment.
Two straight through Ethernet cables via a hub.

Communication Protocol

Communication for Ethernet module or coprocessor update is performed with FTP protocol.
