Status Word/Bit Descriptions

Publication 1771-6.5.126 – March 1998

Notes: For [ ] engineering units, see page 2.

The QI module decodes its own I/O configuration based on parameters
that you provide in the Module Configuration Command Block (MCC).
I/O configuration determines which of the command and status blocks
the module supports. For the module to support command and status
blocks, you must establish the following position input:

Connect a ram (screw) position sensor to input 1.

In the listings of status blocks, each stored-value word is followed by
a bracketed [ ] 2-digit number code denoting the engineering units
and range associated with the value as shown in the following table:

#Code

Inverse time (algorithm) (00.00 to 99.99 inverse minutes)

28

Inverse time (algorithm) (00.00 to 99.99 inverse seconds)

31

Percent (00.00 to 99.99%)

The System Status Block (SYS) reports system status.

The module can always return the System Status Block to the host
processor. It returns this block after each block transfer read (BTR)
request from the PLC processor unless the previous block transfer
write (BTW) to the module was a valid dynamic command block
(DYC) containing a request for some other status block.

The QI module can return any of these status blocks:

Block

Description

IPS

Injection Profile Status Block

HPS

Pack/Hold Profile Status Block

PPS

Plastication Profile Status Block

PTS

Process Trace Status Block

RLS

Inject ERC Values Status Block

After you configure the QI module with a valid MCC, the module
determines if it has access to ram (screw) position data from the ram
(screw) position sensor connected to input 1.
