Input Image Table
See Table 4.
An overview of the Input Image Table modules follows. All of the data
contained in the Input Image Table is written into the dual port memory by
the DSP controller so that the PLC can read it in its master IO space.
Modules 10 through 13
These four are identical 12 byte modules that contain monitored gun
parameter values for four guns. The PLC defines which group of 4 guns is
being displayed on the Operator Interface at any given time by writing the
Gun Page No. into Module 4 of the Output Image Table. The DSP controller
processes this value and places the current monitored parameters for the
group of 4 guns requested by the PLC.
Module 14
This module contains 8 bytes of global status and fault conditions. These
eight bytes provide a quick access to the most important status and alarm
conditions of the system. For example, the lockout state of each gun can be
examined by reading the last byte of module 10 (or 11, 12, 13); however, if
the PLC needs to quickly check if any gun is in lockout, then it can simply
read the first byte of module 14. Address Offset 52 is used to determine the
communication status between Gateway and the Nodes. This byte is
updated every 5 seconds if the Gateway receives any message from any of
the Nodes.
Module 15
This module contains a different value every 1 second so that the PLC may
know that the Gateway’s DSP controller is executing and not locked up.
