Toshiba Service Objects; Parameter Mapping - ICC XLTR-1000 Instruction Manual

ICC
RS-485 port configurations &
options available for the various
Toshiba drives, please refer to the
relevant Toshiba documentation
for your drive.
• When using the "W" function code
to write drive configuration
parameters, be sure to follow
Toshiba's guidelines regarding the
number of times a specific
parameter can be written without
risk of EEPROM damage.

9.11.2 Toshiba Service Objects

The Toshiba ASD master driver uses service objects to describe what services
the gateway should perform. For each service object, the gateway will continually
read the parameters defined within the service object from the designated drive,
storing the value(s) in the database (if the read function is enabled). When data
in the database changes where the parameters are mapped, a write request is
generated to the designated drive notifying it of the changed parameter value(s)
(if the write function is enabled). For more information on configuring Toshiba
ASD service objects, refer to section 8.6.16.2.

9.11.3 Parameter Mapping

Drive parameters are mapped in the database as 2-byte values. This means that
each parameter in a service object takes up two database addresses. For
example, if a service object's starting parameter is "FE00", the number of
parameters is "5", and the database address is "100", then parameters FE00
through FE04 will be mapped at database addresses 100 through 109
(parameter FE00 mapped at addresses 100 and 101, parameter FE01 mapped
at addresses 102 and 103, and so on).
