How to Set Up the MB_SERVER block on an S7-1200 PLC | Authorized Siemens Support | AWC, Inc. 

great video Josh! I had to get reacquainted with this and was having trouble getting it setup until I saw this. Keep the videos coming!

Thank you very much, really helpful !

Thanks. It is very helpful. But what if i want boolean register? Instead of holding register?

I followed these steps but are having issues with ModScan. ModScan worked correctly to start but then hit the 3.5 minute restriction; when I re-opened I cannot re-establish communication. Would you say this is PLC issue or a ModScan issue? Nothing changed on the PLC side and I can still ping successfully.

Followed this turorial to the letter but I'm getting an error even without even trying to connect a modbus client to the PLC . ERROR Output is True and STATUS is 809B. I'm using TIA V13 which only goes to firmware 4.1 on the 1214C I'm using but the PLC has been used with V15 and has been upgraded to 4.2. Is this the reason.
