Configuring the Adapter 3-13
20-COMM-D DeviceNet Adapter User Manual
Publication 20COMM-UM002G-EN-P
When you enter ‘1’ (Reset Module), the adapter will be immediately reset.
When you enter ‘2’ (Set Defaults), the adapter will set all adapter
parameters to their factory-default values. After performing a Set Defaults,
enter ‘1’ (Reset Module) so that the new values take effect. The value of this
parameter will be restored to ‘0’ (Ready) after the adapter is reset.
Viewing the Adapter Status
Using Parameters
The following parameters provide information about the status of the
adapter. You can view these parameters at any time.
Parameter Description
04 - [DN Addr Act] The node address used by the adapter. This will be one of the following
values:
• The address set by the rotary switches.
• The value of Parameter 03 - [DN Addr Cfg].
• An old address of the switches or parameter if they have been changed
and the adapter has not been reset.
06 - [DN Rate Act] The data rate used by the adapter. This will be one of the following values:
• The data rate set by the rotary switch.
• The value of Parameter 05 - [DN Rate Cfg].
• An old data rate of the switch or parameter if it has been changed and the
adapter has not been reset.
07 - [Ref/Fdbk Size] The size of the Reference/Feedback. It will either be 16 bits or 32 bits. It is
set in the drive and the adapter automatically uses the correct size.
08 - [Datalink Size] The size of the Datalinks. It will either be 16 bits or 32 bits. It is set in the
drive and the adapter automatically uses the correct size.
12 - [DN Active Cfg] Source from which the adapter node address and data rate are taken. This
will be either ‘0’ (EEPROM) in which the address from Parameter 03 - [DN
Addr Cfg] and the data rate from Parameter 05 - [DN Rate Cfg] are stored
or ‘1’ (Switches). The source is determined by the settings of the adapter
switches.
14 - [DPI I/O Act] The Reference/Feedback and Datalinks used by the adapter. This value is
the same as Parameter 13 - [DPI I/O Cfg] unless the parameter was
changed and the adapter was not reset.
