Hello, If my slaves adress is 4004, but it has to be in hexadecimal notation. so in modbusmaster reader (simulator on PC) I have to put decimal notation of this 4004 (in hexadecimal) so it means it is 16388... It works very well with this number but in SIEMENS tiaportal I cannot do it I tried to put this adress behind number 4 but it is not possible caouse im out of range.. in siemens u can to 40001 to 49999 or 400001 to 465535... any ideas ??? thank you ------------------------------------------------------------------------------------------ |

Hello,
next description of system. Be careful, you put to this problematic little confusion or chaos. You said: ...If my slaves adress is 4004, but it has to be in hexadecimal notation... I understand your words that value 4004 is decimal notation and need to be set in hex notation, look again to your words. In this case dec 4004 is hex -> 0FA4. Really I'm little bit confused with your question even if I see your next description with hex 4004. Ok, if you did wrong explanation, now to opposite, you definitely mean 0x4004 (hex) and need dec notation for that. Generally (as like in Siemens) you need set decimal value of register address. For Holding register address you need add 400001 (16388 is next range for value, bigger than standard) to your documented address in decimal notation so your final register address is 400001+16388->416389. pls pay attention to future (for sure) to differ values with some prefix in case of hex - give that 0x... with value which is clear as hex notation, any other we can read as decimal. Ok, if you did also another wrong but you mean 4004 as decimal value, what you need put to correct address, your steps are same: 40001+4004->44005 is your final register value. Really I recommend be very clear with information you give to Forum for help asking, now you have hope complete answers for your situation |
