Commands
After the PLC performs a block transfer write, a block read should be
performed to evaluate the response code from the HI 2151 to verify that
the data was received and implemented. The response word will either
show a successful processing of the block or will indicate the first error
encountered in processing of the data.
NOTE:
Setpoints, deadbands and preacts can all accept negative values. To enter negative
values, use the “twos complement” method.
NOTE:
Block Writes cannot be performed while the instrument is in calibration mode. The
calibration must be sealed by pressing enter at Endcal.
