Mirror Failsafe

Output failsafe levels are determined by the 16-bit value stored in holding register 43:

Bits	Binary Values	Failsafe effect
16, 0	00 10 11	IO1 - no change IO1 - OFF IO1 - ON
17, 1	00 10 11	IO2 - no change IO2 - OFF IO2 - ON
18, 2	00 10 11	IO3 - no change IO3 - OFF IO3 - ON
19, 3	00 10 11	IO4 - no change IO4 - OFF IO4 - ON
20, 4	00 10 11	IO5 - no change IO5 - OFF IO5 - ON
21, 5	00 10 11	IO6 - no change IO6 - OFF IO6 - ON
22, 6	00 10 11	IO7 - no change IO7 - OFF IO7 - ON

Broadcast Reset

The Modbus address of a RIO-16D device can be changed by broadcasting (i.e. sending to Modbus address 0) a write to holding registers 171-173.

The write should be done with a single, Write Multiple Registers command. In the first two registers (most signifigant word followed by least signifigant word), you should write the device's serial number. In the last register, you should write the new Modbus address.

As per the Modbus standard, the RIO device will not respond to this broadcast. Immediately after receipt, the RIO device will begin responding to requests made of the new address.

Command State

The user-supported values for the UPCmdState are:

Value	Meaning
0xFFFE	Run
0xFFFF	Halt

To halt execution, write 0xFFFF to UPCmdState. To restart execution, write 0xFFFE to UPCmdState.

To restart program execution from the beginning, read the value of UPLoadAddr and then write this value to UPVPC and 0xFFFE to UPLoadAddr in a single operation.
