Hi, If you build up the ANY pointer you can specify the memory area. For example 16#82=Output area (O). See details in this topic:ANY, POINTER in SCL Anyways I never used SFC20 to write Q area. Have you considered to use "SFC 15 "DPWR_DAT"". See System Software for S7-300/400 System and Standard Functions Volume 1 and Volume 2 under "16.6 Writing Consistent Data to a DP Standard Slave/PROFINET IO Device with SFC 15 "DPWR_DAT"" |
