Thank you for your reply. The example provided looks like its for STL / LAD but I am using SCL . Can you please provide me inof. related to my specific case. Please see below. I have declared a DATA BLOCK at the very top of OB1 (See attached file). I would like to fill the array with ASCII data. I would like transmit the data in ASCII to a CP 340. The attached file shows what I have written but I am having problems compiling the file, I get an error. Any help that can be provided would be appreciated. Attachmentcp 340 prg.pdf (433 Downloads) |

Hello jpapu9; The SCL compiler tells you the fault appears when you write .VAR. in your program. If you compare with the Data_Block examples in the S7-SCL V5.3 for S7-300/400 manual, you will see that you do not use the 'VAR/END_VAR' declaration in a Data_Block (this is used to declare STAT variables in a FB). Simply write your variable declarations after your Data_Block DB4 initialization. Hope this helps, Daniel Chartier |
