hi, the amount of data you can read/write depends on what CPUs you use. We just know one of your CPUs. Whats your second? Is there any error on the blocks? Have a look to this FAQ how to evaluate the error-information of system-blocks: How do you evaluate the status of system blocks in STEP 7 (TIA Portal)?hope this helps, regards, |
