Is there a native protocol command to set a single output bit, or must I read the status of the output channel(8bits) and change the bit I want then write the output channel.

There isn't a native command that let you force a single bit ON or OFF so you do have to read in the output channel, make your changes and write back to the output.
MOBDUS does have a function that affects single bit which is function 05. You could use the MODBUS ASCII protocol for such a purpose.
