L #TUDA // high byte -> MB 250, low byte -> MB 251 -> lost T MW 250 L #NUDA // high byte -> MB 251, low byte -> MB 252 T MW 251 L #TUSW // high byte -> MB 253, low byte -> MB 254 -> lost T MW 253 L #NUSW // high byte -> MB 254, low byte -> MB 255 T MW 25 // -> presume MW 254 !!! L W#16#EEFF // end adr. MB 255 L W#16#EA15 // end adr. BS 11 // TNB 6 // Block copy MB 250 .. 255 -> BS 9 .. 11 //CALL SFC 20 ( // SRCBLK := P#????? BYTE 6 , // RET_VAL := conv_ret_val, // DSTBLK := P#????? BYTE 6 // ); // * Error in Line 2794 (FB 114): CALL SFC20 generated. Please complete parameter list. * L 0 T MW 250 T MW 252 T MW 254 // L BS 11; // contains #NUSW // * Error in Line 2801 (FB 114): Invalid operator. * L W#16#3 ==I R #FEHL BEC S #FEHL If BS are not used anymore in the plc program you can ignore this part of the program. Just use the parameters and temp var. If BS 9 .. 11 are used elsewhere they should be replaced by a data block. Good luck

Check out chapter 13 of this manual. You cannot convert this block.Use S7 SFC blocks to write and read PLC clock if somewhere else in PLC program the CPU time is needed. Kind regards, BV
