The expression uses the values retrieved from the INP x links as operands, though constants can be used as operands too.
RRM 3-14 Calculation
The EGU string is solely for an operator’s sake and does not have reverence be used. No Run-time Parameters These fields are not configurable using a configuration too and none are modifiable at run-time.
The result is stored in RPCL. These fields are listed in Scan Fields.
Log base 10 unary LOGE: Nested parenthesis are supported. Natural log unary LN: The CALC field contains the infix expression which the record routine will use when it processes the record. No Literals Standard double precision floating point numbers Inf: Natural log unary EXP: A routine postfix is called to convert the infix expression in CALC to reverse polish notation.
Redord semicolon is used to separate expressions.
These fields are not configurable using a configuration too and none are modifiable at run-time. The comma is supported when used to separate the arguments of a binary function.
The keyword VAL returns the current contents of the VAL field which can be written to by a CA put, so it might not be the result from last time the expression was epkcs. It is this expression which is actually used to calculate VAL.
The EGU field contains a string of up to 16 referwnce which is supplied by the user and which describes the values being operated upon. The following alarm parameters which are configured by the user define the limit alarms for the VAL field and the severity corresponding to those conditions.
Minimum any number of args MAX: This page Page Discussion History.
Retrieved from ” https: Alarm Fields lists other fields related to alarms that are common to all record types. Browse Main page Recent changes Random page Help. CALC can be changed at run-time, and nanual special record routine calls a function to convert it to Reverse Polish Notation.
See Alarm Specification for a complete explanation of alarms and these fields.
They are used to process the record. See Address Specification for information on how to specify database links. The Calc record has the standard fields for specifying under what circumstances the record will be processed. The LALM field is used to implement the hysteresis factor for the alarm limits.

No Monitor Parameters These parameters are used to determine when to send monitors for the value fields. Right shift Assignment Operator: Conditional Expression The C language’s question mark operator is supported. Sets the upper control and the lower control limits for a field. Also, the RNDM nullary function can be included as an operand in the expression in referencw to generate a random number between 0 and 1.
