Use the above procedure to enter the required words of the write block transfer
instruction. Be aware that the block length will depend on the number of
channels selected and whether biasing and/or calibration is or is not performed;
for example, the block may contain only 1 word if no bias or calibration is
performed but may contain 14 words if using 6 inputs with bias and calibration.
The PLC–2 family write block transfer data file should look like Figure B.1.
