Source
Port: This drop-down list determines the ETH-200 port that this
point will obtain its value from and write values to.
•
Edit
Protocol: This drop-down list allows the selection of any of the point’s
protocol-specific attributes. Once selected, the point’s attributes related to
the chosen protocol will be displayed in the middle portion of the point box.
The available protocol-specific selections and corresponding attributes are as
follows:
•
Toshiba:
o
Address: The address of the
Toshiba ASD that this point
refers to. This address field is
only used in conjunction with
the Toshiba RS485 protocol: Toshiba common-serial port
connections are point-to-point, and therefore do not require
targeting a drive at a specific address.
o
Parameter: The Toshiba ASD parameter (in hex, 0000-FFFF)
within that drive that this point refers to.
•
Mitsubishi:
o
Address: The address of the
Mitsubishi or MGI drive that
this point refers to.
o
Parameter: The parameter within that drive that this point refers
to.
•
Modbus
Master:
o
Address: The network address
of the Modbus slave that this
point refers to.
o
Register: The holding register
or input register that this point
will access. The type of
register accessed (holding or
input) will be determined on the basis of the “Read Function”
setting (see below).
o
Write
Function: Allows selection of the Modbus “write” function
code that will be used to write to the designated holding register
(this setting does not apply to input registers, as they are read-
only). The default setting is “Write Multiple Registers” (Modbus
function code 16). Alternatively, this setting can be changed to
“Write Single Register” (Modbus function code 06) in order to
connect to those Modbus slave devices that do not support
function code 16.
