Chapter 14 SPI Protocol Option

The Altanium controller communicates with central networks or molding machines that
support the Society of Plastics Industry (SPI) standard protocol.
The system takes the device ID of 26h on the SPI communications channel. This ID has been
assigned to general-purpose temperature controllers with multiple zones. The system
supports a subset of the commands that have been defined for this ID. The commands for
this ID that are not supported by the system do not have equivalent functions in the system.

14.1 SPI Command Summary

The SPI commands supported by the system are listed below. The system supports the
defined poll and select functions for each command. If a selected command is made to all
zones in the system, the error requirements must be satisfied for every zone before an ACK is
returned.
