Nodes of different colours represent the following:
Solid arrows point from a parent (sub)module to the submodule which is descended from it. Dashed arrows point from a module being used to the module or program unit using it. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| integer, | intent(in) | :: | LoopNum | |||
| integer, | intent(in) | :: | LoopSideNum |
Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed arrows point from an interface to procedures which implement that interface. This could include the module procedures in a generic interface or the implementation in a submodule of an interface in a parent module. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

! PURPOSE OF THIS SUBROUTINE:
! Check for plant control errors revealed as run away fluid temps
! halt program so it won't siliently run in out of control state
! METHODOLOGY EMPLOYED:
! compare plant temps to plant min and max and halt if things run away
! sensitivity can be adjusted with parameters, picked somewhat arbitrary
