Hi!
Thanks for supporting this library.
I'd like to seek your advice on an issue I'm having surrounding *writing* to
Modbus registers.
I have a code snippet as follows:
!image-2022-05-30-13-31-56-320.png!
I'm able to make about ~100 requests successfully, until I encounter a`{{`
PLC Connection Exception: Error creating channel error{}}}. This is consistent
with multiple tries.
*I've tried using `{}CachedDriverManagers / PooledDriverManagers{`}, but
this will result in a NullPointerException when I tried to use its
`{}PlcConnection object to create a PlcWriteRequest.Builder{`}. Essentially,
the "builder" object is null:*
!mb2.png!
*However, I'm able to create `{}PlcReadRequest builders for reading data; no
NullPointerExceptions{`}:*
This is how I'm creating the `{}CachedDriverManager{`}:
!mb3.png!
I've noticed that I will never encounter a maximum buffer limit reached for
connections created from the `{}CachedDriverManager{`}, used to make Modbus
read requests. Hence, I considered using connections created from the
CachedDriverManger to make Modbus write requests, __however I get a
NullPointerException whenever I try to create a PlcWriteRequest.Builder object
from CachedDriverManager__.
Hope you could help point me in the right direction, been stuck at this for
a couple of days.
Thanks!
Regards,
Max
