use the Auto-CLEAR function.
Auto-Addressing defines whether or not the CS1/CJ1W-PRM21 Master DTM
will automatically map the I/O data in such a way that no gaps exist in the I/O
data. If enabled, the user does not need to handle the exact mapping of I/O
data on to the PLC memory areas. Refer to section 3-4-3 Defining and
Changing I/O Mapping for more information on I/O data mapping.
After making the changes, select the Save button in the lower right corner of
the user interface to accept the changes. Next select the Bus Parameter tab to
display the Bus Parameters.
The Bus Parameter setup tab contains all the settings required to setup the
communication cycles on the network. The settings depend on the selected
baud rate, the number of slaves, the amount of I/O data per slave, etc.
By default, the CS1/CJ1W-PRM21 Master DTM will calculate the bus param-
eters, based on this information.
recommended to do that. Making the wrong configuration may lead to unex-
pected behaviour.
An example of the Bus Parameter tab is shown below.
The baud rate has been set to 1500 kBit/s. The amount of slaves and the
amount of I/O data, results in a poll cycle time of approximately 3.8 ms (Min
Slave Interval).
After making the changes, select the Save button in the lower right corner of
the user interface to accept the changes. Next select the Slave Area tab to
display the I/O Mapping.
