Command Word/Bit Descriptions

Publication 1771-6.5.88 – July 1997

After you configure the QDC module with a valid MCC, the module
determines if it has access to ram (screw) position data from the ram
(screw) position sensor. The module considers these command
blocks recognizable and can return these status blocks when it has an
analog input reserved for a ram (screw) position sensor, and the
sensor is physically connected to input 1.

The host processor can write any of these command blocks to the
QDC module to control clamp position

After you configure the QDC module with a valid MCC, the module
determines if it has access to clamp position data from the clamp position
sensor. The module considers these command blocks recognizable and
can return these status blocks when it has an analog input reserved for a
clamp position sensor, and the sensor is physically connected to input 3.

The host processor can write any of these command blocks to the QDC
module to control ejector position:

After you configure the QDC module with a valid MCC, the module
determines if it has access to clamp and ejector position data from
both position sensors. The module considers these command blocks
recognizable and can return the status block when it has analog
inputs reserved for ejector position and clamp position sensors, and
both sensors are physically connected to inputs 3 and 4 respectively.
