Parameter Parameter
Name Type
element_list channel list
•
[SENSe:]DATA:CVTable? (@<element_list>) allows you to "view" the latest
values of internal algorithm variables while algorithms are executing.
•
The Current Value Table is an area in memory that can contain as many as 502
32-bit floating point values. Algorithms can copy any of their variable values
into these CVT elements while they execute.
•
There is a pre-defined organization for the first part of the CVT. It is divided
into 32, 10 element segments. This allows up to 32 PID algorithms to place up
to 10 variable values each into the CVT. The pre-defined PIDB algorithm can
return 4 variable values. The PIDC algorithm (defined as a custom algorithm)
can return up to 9. With up to 32 PIDs possible, 320 elements are allocated for
"standard" PIDs. ALG1 can use elements 10-19, ALG2 can use elements
20-29, ALG3 can use elements 30-39, etc. through ALG32 which can use
elements 320-329. The values stored in each segment are:
ElementVariableDescription
xx0 Sense Process value monitored(PIDB & C)
xx1 Error Setpoint value minus Sense value(PIDB & C)
xx2 OutputProcess control drive value(PIDB & C)
xx3 Status Bit values indicate Clips/Alarms limited(PIDB & C)
xx4 SetpointSetpoint value
xx5 Setpoint_DValue of Differential term from setpoint(PIDC only)
