[TRNSYS-users] Error message 19

[David BRADLEY]

Rabea,

   I think that if you delete the Type9 from your simulation and then 
re-add it then the error might go away. TRNSYS refers to outputs by two 
numbers separated by a comma. The first number designates the UNIT 
number of the component producing the output and the second number 
(after the comma) designates which output is needed. Something like:

myEquation = [9,5]*32

in the input file means the 5th output of UNIT 9 should be multiplied by 32.

 From time to time, I have seen projects in which there was an obviously 
incorrect UNIT number as in:

myEquation = [2387538998347,5]*32.

Since the Studio assigns unit number and writes the equation syntax, you 
can't manually correct the equation itself. However, if you delete the 
component that corresponds with the bad unit number, then add it back 
again then the error usually goes away.

kind regards,

  David
