3.9. Vender Specific Device Profiles
Class code 0x64. This object provides VF-AS1/PS1’s Parameter access.
All parameter’s Attribute ID is 3.
Refer to the following about each parameter’s Instance ID.
Attribute ID of all parameters are 3. Moreover, about the instance ID of each parameter, it
becomes "parameter communication number + 0x4000".
In the case of the parameter from which a communication number begins in "F", it
becomes "parameter communication number - 0x8000 (same as bit15 set to 0)".
About the details of the contents of a parameter, please refer to a VF-AS1/PS1
instructions manual.
Example 1.
In case of Basic parameter “CMOd - Command mode selection”,

Communication No: 0003 -> Instance ID: 4003

Example 2.
In case of Extended parameter “F268 - Updown frequency default value”,

Communication No: 0268 -> Instance ID: 4268

Example 3.
In case of Monitor parameter “FE03 - Output current”,

Communication No: FE03 -> Instance ID: 7E03

* Monitor parameter can access "Get" only.
For example, when "Acc. time" is set to 5 sec., since the minimum unit is 0.1s,
5 / 0.1 = 50 = 0x0032 (Hex.)
Since the communication number of " Acc. time" is "0009", it writes "0x0032" in instance ID
"4009."
Moreover, when the "highest frequency" is read, "0x1F40" is read.
0x1F40 = 8000 (Dec.)
Since the minimum unit is 0.01Hz,
8000 * 0.01 = 80Hz
3.10. About EDS-file
Even if access to each parameter of VF-AS1/PS1 uses a configuration tool and an EDS
file, it is possible. As for acquisition of an EDS file, it is possible to download from
homepage of our company.
Please use what was in agreement with the software version of usage's VF-AS1/PS1.
