Simatic Manager can support redundancy CPU but TIA portal so far not support.

I-DB is the safety Program auto-generate DB which is not allow programmer to access. Based on this error message is insufficient to find out the problem, could you provide more information?

You may consider to use Array in your case. First, arrange your alarm into few categories. Assume now I have 4 categories and they have different number of alarm, category 1: 30; category 2: 45;   category 3: 50;   category 4: 25;   Second, create 4 array of bits based on number of alarm bit in that category: category 1: ARRAY [0..29] OF BOOL; category 2: ARRAY [0..44] OF BOOL;   category 3: ARRAY [0..49] OF BOOL;   category 4: ARRAY [0..24] OF BOOL;   Third, you can map the alarm bit into the dedicated alarm bit by using Ladder diagram or structure text or other language. Assume the array is under DB101. DB101.DBX 0.0 := Emergncy_Stop_Alarm;  (*Structure Text example*) I'm using DB address (DB101.DBX 0.0) here but if you assign a name in your program, you can use the name to call.   Lastly, wish my idea could help you.

1) I checked the HMI tags; they appear to match the plc tags as I expect, but when I press the HMI buttons on the screen, in online mode, I cannot see the tags become energized in the ladder.   How you confirm the HMI tags is match to the PLC Tags. Is it by DB address? You need to make sure the HMI is link to the correct PLC addrrss.   2) The corresponding manual controls subsequently do not work.  The manual controls that do work, I can see the bits energize when I press the HMI buttons.   What means corresponding manual control subsequently do not work and the manual control that do work? This mean manual control work or not working?  

Try to delete SDB1002 and download again?

Hi Allen, Yes, your CPU is taking 24VDC as incoming power supply. Jairus's photo is another CPU modal. https://www.sahkonumerot.fi/2702074/doc/technicalinfodoc/ CPU1214C.pdf

I guess you could use "Read_Var" and "Write_Var" to read and write.

Hi everyone, currently I have a problem need to receive data from a Omron PLC to another Omron PLC. I would like to receive data from source EIP21 to destination ETN21. The steps I have done is:1) MOV #0020 D16180 (*Read 32 Words From Source*)2) MOV #0000 D16181 (*Use Local Network*)3) MOV #8400 D16182 (*Source PLC IP address is 192.168.5.132*)4) MOV #0003 D16183 (*Resend Time Set To 3s*)5) MOV #0000 D16184 (*Response Monitor Time Set To 0s*)6) RECV 400 D16130 D16180 (*First Source Word: D400, First Destination Word: D16130, First Control Word: D16180 *)Can help me check the is there any problem and any more steps I miss? Thank you.
