Reset Button
Some module functions, such as reading module switch settings, are performed
only at startup. The Reset Button is a momentary contact switch that allows you to
restart the module without having to cycle power to the base. It is recessed to
prevent inadvertent use. To reset the module, use a small object such as the tip of a
ball point pen to depress and hold the switch for approximately one second. When
the switch is released, the module will begin the startup sequence (see Section 3.2).
Module ID Switches
The Module ID switches are used to identify the module to a DHCP server. See
APPENDIX E. USING DHCP. When the switches are set to a value of 00, the
module will obtain IP parameters from EEPROM. A value of FF selects a special
configuration mode. By depressing the actuator at the top or bottom of the switch,
you can decrement or increment the switch value. The top switch is the most
significant digit in the Module ID.
NOTE:
The value of the Module ID switches are read only at module startup. They are ignored if you are
using the PLC start option.
Serial Port
The Serial port can be used to set network parameters such as the IP address when
no other method is acceptable. It provides a subset of the RS-232 interface that
should work with most PLC programming cables.
Ethernet Port
The Ethernet Port accepts standard 10BaseT or 100BaseTX cables (shielded or
unshielded twisted pair). To connect the cable, align the connector tabs and insert
the cable until the restraining lock snaps in place. To remove, press the cable release
and remove the cable.
3.2. Module Startup
When power is applied to the module or the module is reset, the module will
perform a lamp test which will flash all the software-controlled LEDs in sequence.
Once the test has been successfully completed, the module will read the network parameters and start
the application firmware. The exact sequence depends on the startup method you have selected. See
Choosing a Module Startup Method on page 9. During the startup process, the Module Status
indicator will blink green. Once the application firmware has successfully started, the Module Status
indicator will be steady green. When the network server has successfully started the Network Status
LED will be steady green.
