3. Implementation of the communication option cards
Configuring communication monitoring
Since the Altivar 38’s communication monitoring time out is the same as the default value of the Altivar 61’s [Modbus time out] (ttO)
field (10 s), there is no point in modifying the value of this field.
Modification of these parameters will only take effect on the next power-up.
After transfer of the drive configuration by the PowerSuite software workshop, the
[Channel switching] (CHCF) parameter is
automatically assigned to
[8 serie] (SE8), thus providing access to memory mapping for the Altivar 38 compatible with the Altivar 61.
PLC configuration and application
The fact of opening the Altivar 61’s "ATV38 compatibility" memory zone (SE8 mode) means that no changes need to be made in the PLC
application.
However, in response to a function 43 identification request (16#2B) the drive will identify itself as an Altivar 61, not an Altivar 38.
Scenario 2 Using the built-in port when replacing the ATV38 terminal port
Configuring the drive
This example is implemented in the PowerSuite software workshop and consequently all the settings linked to the configuration parameters
(address, baud rate, parity) will be assigned automatically, identical to the Altivar 38.
