Hello Experts, 

I have to move data of 80 bytes (Char) from a DB to process image output. The instruction BLKMOV shall work for this but the problem is how I can write or define destination address when it is not possible to define a tag under PLC tag table of this size.

Hardware : CPU 315F-2 DP

Software : TIA Portal V13

I have published one thread linked to this problem so far I know it is not possible.

Hi Fani.Ing,

U can write P#Q 33.0 byte 80. 

But for consistent writing Q data, u should use SFC14/15.

Hi Sachinpatke

Thanks for valuable suggestion. This P#Q33.0 BYTE 80 work fine for me.

I should use SFC 15 as you suggest. I been looking at examples and in one of previous project where I used this earlier still not able to figure out why I have error code 8090. Please have look at attached picture. Any idea why I have this error?

hi Fani.Ing,

have you checked the Tips, that the help has given you?

21hex means that the projected output-address should beginn at 33 and the module must be 80 bytes long.

regards,
