Rockwell Automation AutoMax R-Net Processor Module - Manual (Page 19)

4Ć3
4.1.1.3 Register 13 (Slot Number)
Register 13 indicates the slot location of the AutoMax RĆNet
Processor module.
4.1.1.4 Register 14 (Messages Received Count)
Register 14 indicates the number of messages received by the
AutoMax RĆNet Processor module since powerĆup. This register will
increment (up to 32767) as messages are received. This register is
reset to zero at powerĆup or can be reset by the user.
4.1.1.5 Register 15 (Receive Timeouts Count)
The AutoMax RĆNet Processor module expects to receive a response
to a message within the time period specified by register 22. If a
response is not received, a receive timeout occurs and is logged in
this register (up to 32767). This register is reset to zero at powerĆup
or can be reset by the user.
4.1.1.6 Register 16 (CRC Error Count)
CRC (Cyclic Redundancy Check) is an error detection scheme to
insure the validity of the data that is sent and received. This register
will increment (up to 32767) if a CRC error occurs. This value will
ideally remain zero. This register is reset to zero at powerĆup or can
be reset by the user.
4.1.1.7 Register 17 (Overrun Error Count)
Overrun errors are caused by receivingtoo many bits of data in a
transmission frame. (This is typically caused by missinga stop bit.)
This register will increment (up to 32767) if an overrun error occurs.
This value will ideally remain zero. This register is reset to zero at
powerĆup or can be reset by the user.
4.1.1.8 Register 18 (Illegal Message Count)
Register 18 will increment (up to 32767) each time a message frame
is received that did not contain enough bits of data. This can be
caused by transmission problems or improper protocol. This value
will ideally remain zero. This register is reset to zero at powerĆup or
can be reset by the user.
4.1.1.9 Register 19 (Messages Transmitted Count)
This register increments (up to 32767) each time a message is
transmitted from the AutoMax RĆNet Processor module. This register
resets to zero at powerĆup or can be reset by the user.
4.1.1.10 Register 20 (Lost Token Count)
This register increments (up to 32767) when no activity is detected on
the network within 10 ms.
4.1.1.11 Register 21 (Maximum Node Number)
This register defines the number of nodes on the network. At
powerĆup, the AutoMax RĆNet Processor CPU will set this location to
7 more than the node address (up to 250). For efficient operation,
