Hi, sadly I don't have any example project for FB45 with TIA V11 and it's hard to explain via forum texting. Imean, if you could do an init_run, it's no magic to also do reads and writes. Just look at the FB45 manual: http://support.automation.siemens.com/WW/view/en/90063944 This manual was made for STEP 7 V5.5 but it works similar to STEP 7 V11. |

Hi, which values did you use at "length" and "address MDS" in your MOBY CMD_d data block? |

all address are ok except MDS address 16#0. it required to change in command db (07CF for MDS D400)? |

there is no error on FB45 either RF180C Or Rf260R. Just want to confirm that the address MDS is the UID of MDS or Memory Length address? |

If starting 2000 bytes reserved for user memory then if we put MDS address 16#0 then it should be read and write properly. "//Commonds MOBY" "MOBY_CMD".CH_I[1].command=02(forwrite=1) "MOBY_CMD".CH_I[1].sub_command=0 "MOBY_CMD".CH_I[1].length=10 "MOBY_CMD".CH_I[1].address_MDS=16#0 "MOBY_CMD".CH_I[1].DAT_DB_address=0 "MOBY_CMD".CH_I[1].DAT_DB_number=1102 But issue is when give command for write the ready signal goes low(writing start) and after write completed again high. at same time if we give read command nothing changes and there is no error in both cases. is it writing properly? is it required configuration of Tag?
