VCL RUNTIME RATES
VCL is an interpreted language. Each line of VCL code is converted into an array of pseudo-code
by the WINCL complier which can then be flash loaded into the controller. The controller
interprets these pseudo-codes one line at a time while the system is running (powered). The
table below lists the rate that the VCL interpreter runs each of the various functions (Service
Rate) and lists how many of each function is available to the VCL software (Instances):
FUNCTION FUNCTION FULL NAME INSTANCES SERVICE RATE
ABS Absolute Value 2 4 ms
