The first line under 3.7 states,
"For a viual diagnosis, communiction status and device status must be indicated by LED's." The
last line in the table indicates that the Device
status is optional. Anyone know which is correct?
Also, should the required communication LED that is switched on during "frame sending" reflect the status of the slave transmit lines (any slave
transmitting would turn it on) or the status of
the particular slave on which it is located? The
former would place the LED after the slave transmit driver and the latter would place it
before the slave transmit driver.
