COMP_VAL1 (Floating point with status) |
0 (Determined by source) |
Access: Configurable, Tuning NVM: Restored on Restart |
The first comparative value. Compared with DISC_VAL to calculate EQ, GT, LT, and NEQ. |
|
COMP_VAL2 (Floating point with status) |
0 (Determined by source) |
Access: Configurable, Tuning NVM: Restored on Restart |
The second comparative value. Used as part of the range that DISC_VAL compares against to calculate IN_RANGE. |
|
DISC_VAL (Floating point with status) |
0 (Determined by source) |
Access: Tuning NVM: Restored on Restart |
The input comparison value. Used with COMP_VAL1 to calculate EQ, GT, LT, and NEQ. Compared against the range of COMP_VAL1 - COMP_VAL2 to calculate IN_RANGE. |
|
EQ (Discrete with status) |
0 |
NVM: Preserved on Download |
Equal to. Compares COMP_VAL1 with DISC_VAL. Discrete output (True=1/False=0). |
|
GT (Discrete with status) |
0 |
NVM: Preserved on Download |
Greater Than. Compares COMP_VAL1 with DISC_VAL. Discrete output (True=1/False=0). |
|
IN_RANGE (Discrete with status) |
0 |
NVM: Preserved on Download |
In range. Compares DISC_VAL against the range of COMP_VAL2 and COMP_VAL1. |
|
