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
