61 Configuration Register:

This is a single byte, 8 flags.

bit 0 - 2

not used.

bit 3

Disable re-transmission of COS messages R/W . When this bit is set ALL event driven messages are sent only

once per event. Unacknowledged messages are not resent.

bit 4 - 7

not used.

This attribute is stored in non volatile memory.

* These parameters are optional

0 NO-OP:

This is used primarily during “Autobaud” and to solicit a response from another node to verify bus integrity.

No action is performed by our device.

1 Change Address:

There are two methods to change the address.

•

If the message contains one or two data bytes the address is changed to the address defined by the first byte.

The second byte is ignored.

•

If the message contains eight data bytes, then bytes 3 and 4 are checked against the Vendor ID.

Bytes 5-8 are checked against the Serial Number. If the Vendor ID and Serial Number are correct, then byte 1 is

used to determine the new address. If either is not correct the message is ignored.

2 Initiate Self Test:

This action initiates a self test sequence internal to the node. This action is acknowledged prior to

the start of the self test. An Event ID 0 is then transmitted only if internal errors are found.

6 Reset Errors:

This action clears the error flags in both bytes of attribute #9, Bus Diagnostic Register.

8 Enroll:

Enroll returns a 6 byte message. The first four data bytes are the Serial Number and the remaining two bytes

are the Vendor Identification Number. The firmware waits for a random delay, up to 10 ms, before responding to this

action. This delay makes it possible to detect multiple devices with the same logical address.

51 Force Input/Output Variable State:

This forces the logical state of the Input, Attribute #18. The data contains a

Boolean single byte: 00 or 01.

52 Remove Force Input/Output Variable State:

This function removes the forced state, and restores normal operation.

53 Read Primitive Tag:

This action is called with one byte of input data - the attribute number. This action responds

with the following 3 bytes of data: Attribute # (unsigned 8), Primitive Tag (unsigned 16).
