Code changes.
To change the Request Bits, first set the Request Bits to 0000 then change
the setting. The same applies when periodically executing the same operation
command.
Example: Changing a Single Action to a Multi Action
1. For a single action, the Response Bits are set to the single action value,
0001.
Note The Request Bits cannot be changed directly to 0002 because the
setting will not be accepted.
2. Change the Request Bits to 0000, then confirm that the Response Bits
have been set to 0000.
3. Then change the Request Bits to the multi action setting of 0002.
• Each set of Request Bits has a corresponding set of Response Bits. Once
the Request Bits have been set, the Response Bits operate in the order
shown in the following table.
