Hi mohali23, 1- Is what I stated right ? --> No. IOID will define whether module to be read/written is input or output type. U can read/write input module data record. Similarly U can read/write output module data record. Data records is nothing but configuration data of module. Also LADDR is the starting [local] address of module. U have to use lowest address in case input and output starting addresses are different. So U will need to use B#16#54 as IOID if input has lower address than output address and vice-versa. 2- What does it mean to set IOID = B#16#F4 ? --> No idea. |

Thank you brother sachinpatke for answer, but excuse me I'm still confused .. what does it mean to write input module data record?, I mean what I know is that I can only read from an input module. For my example if I want to write process image of outputs to the soft starter (data record 68), I have to use sfc58 to write it. Now I have 3 cases 1- PIW and PQW address are 128...129 in HW configuration, Should IOID set to B#16#54 ? 2- PIW 128...129 and PQW 130...131, Should IOID set to B#16#54 ? 3- PIW 130...131 and PQW 128...129, Should IOID set to B#16#55 ? And because I want to write to the soft, should LADDER be set to PQW address in all cases or to the lowest address ? |

For my example if I want to write process image of outputs to the soft starter (data record 68), I have to use sfc58 to write it. Now I have 3 cases --> Data records is for module parameters/properties. The module is either input or output type. In case of mixed module like DIO, u have to use lower LADR address and use IOID of lower address module type. Have a look at the manual--- http://home.hit.no/~mortenp/A289/Manualer/Simatic/S73bhb_e.pdf |

Thank you, I got it. If you please, tell me if you knew anything regarding setting IOID = B#16#F4. |

Hi mohali23, If you please, tell me if you knew anything regarding setting IOID = B#16#F4. --> Can u share the manual where this IOID is mentioned ? |

unfortunately it is not mentioned in any manual, it is used in a plc program in the factory I work in. |
