A plant is divided into hardware zones. Here you can define variables for the entire system.
With right click you have some extra functions. (e.g. Add hardware zone, rename plant)
Total Constantly Montiored Zone
Each T.C.M.Z is split into 3 defined areas, Fatal Fault , Gate/Fortress Fault and Warning Fault.
TheFatal Fault Flag is a PLC Output which monitors the status of the Fatal Fault area of the Hardware Zone T.C.M.Z matrix such that any Fatal Fault Lamp Marker energized will cause the Fatal Fault Flag to energize.
This Flag is used in all Step Sequence fault matrices to cause a C.M.Z fault and inhibits Auto/Manual Release in every sequence within the Hardware Zone. A standard Lamp Marker in every Sequence Fault matrix is dedicated to this fault.
The Fatal Fault must be corrected before Auto or Manual Release is available. Fatal Fault can not be overridden.
The Gate/Fortress Fault Flag is a PLC Output which monitors the status of the Gate fault area of the Hardware T.C.M.Z matrix such that any Gate fault Lamp Marker energized will cause the Gate fault Flag to energize.
This Flag is used in all Step Sequence fault matrices to cause a C.M.Z fault & inhibit Auto and Manual Release in every sequence within the Hardware Zone
For every Hardware Zone, there will be an associated warnings matrix.
The warning messages do not affect machine operation. However the status of the warning matrix is continually monitored by ‘HMI’ which displays any active warning messages.
The Selmo standard has a parent parameter Layer in the plant. The input and output data points are defined there. That makes the process flexible and adaptable.
A Hardware Zone is defined as an area of a machine/cell which is afforded independent Auto/Manual control. Each Hardware Zone has it’s own dedicated A/M panel functionality built into the HMI. Each HMI can accommodate the A/M panels for 3 Hardware Zones. A Hardware Zone will contain/control one or more Step Sequences based on the configuration of the machine/cell.
With right click you have some extra functions. (e.g. Add sequence, rename hardware zone)
Hardware Zone T.C.M.Z
Each hardware zone also has a T.C.M.Z
A sequence describes the logical flow of a machine step chain.
It consists of the logic layer and the system layer. There the sequences of the step chain are fixed and driver models are added.
