frame field elements. The resulting complete basic frame is calculated in the channel as a
result of the write operation. Whenever a basic frame is written, the complete basic frame is
calculated again.
$P_BFRAME Current first basic frame in the channel
The predefined frame variable
frame with the field device of 0, which is valid in the channel, in the parts program. The
written basic frame is immediately included in the calculation.
