│ For Model 525 and 535 controllers:
│ This rung writes the status register to coils. It copies
│ the 16-bit word at V405 (Axis 1 Status Bits) to coils C65
│ through C80. This lets you use the contacts to monitor the
│ axes' status without using the less-efficient bit picks. The
│ At Command Position bit (Status Bit 16) is written to C65, the
│ first coil.
│
│ For Model 545 and 555 controllers:
│ A bit pick routine will work as well.

│ This rung halts the axis when hydraulic or electric power is
│ turned off. It writes a 72 ('H' or 'HALT' command) to V456,
│ the Axis 1 command register. This prevents the integral
│ term from winding up.
