Yaskawa P-Drive Acyclic Parameter Access Mechanism - YASKAWA PROFINET JOHB-SMP3 Technical Manual

Using the "Read Record"function block in the PLC, enter the value 200 (Hex) (or 512 decimal) into the index
field. The function block will then return (via the record field) an integer value like 1000, which represents 10.00
seconds.
Example: Write drive parameter C1-01 [Acceleration Time 1]
The MEMOBUS/Modbus address for C1-01 (from the drive Technical Manual) is 200 (Hex).
Using the "Write Record" function block in the PLC, enter the value 200 (Hex) (or 512 decimal) into the index
field. Enter the desired new value, as a 16-bit integer into the record field. If 5.00 seconds is desired, enter a value
of 500.
The parameter change will take effect immediately, but will NOT be saved if power is lost.

Yaskawa P-Drive Acyclic Parameter Access Mechanism

A Yaskawa P-Drive acyclic parameter access mechanism can be used to access Yaskawa P-Drive parameters and
drive parameters using an index of 0xB02E and the structure in
Requests and responses between the IO-Device and the IO-Controller or the IO-Supervisor are transferred with
the Record Data Objects.
Figure 8.2 Yaskawa P-Drive Acyclic Parameter Access Mechanism Structure
A write request is first sent containing the parameter request.
If the write request is valid, the JOHB-SMP3 acknowledges it with request accepted. The IO-Controller then
sends a read request. If the JOHB-SMP3 is still busy performing the internal parameter request, it will return a
negative response with the error code "0x11" (State conflict). In this case, the IO-Controller repeats the read
request until the JOHB-SMP3 has the Yaskawa P-Drive response data ready.
If the write request is invalid, a negative response is returned with an error code.
Base Mode Parameter Access - Local
The DO-ID field in the Record Data Object request header is not evaluated by the parameter manager. Parameters
can be read through any slot in the configuration.
