We can set the buffer size in the HW option with Step7 programmer software, when two R/W Heads be connected with BIS M-60XX processor
We use the Balluff bis m-60xx processor, which can normally connect two read-write heads. When you need to reconfigure, allocate the buffers of the two read / write heads through the GSD file settings.
Balluff bis m-60xx processor needs to allocate the buffer of the first read / write head in the last byte of the module parameter in the configuration.
The second read-write head is buffer minus the buffer of the first read-write head.
