Communicating via the Interface Module
Using This Chapter Once the PLC-5 Ethernet interface module is connected and
configured, the interface module and the processor function as
one unit.
Applying Power to the Chassis After installing the interface module into the chassis and configuring
channel 3A for Ethernet communication, apply power to the 1771 I/O
chassis. Upon power-up, the PLC-5 Ethernet interface module
performs the following functions:
• establishes communication with the PLC–5 processor
• broadcasts BOOTP requests (if BOOTP is enabled; see page 3-4)
Monitoring the LEDs If your module is operating correctly, you see these LED indications:
• Status LED remains lit green
• Ethernet Transmit LED briefly lights green when transmitting
packets
If the LEDs do not indicate the above normal operation, see the
following table for an explanation of indicator lights.
