Communication settings
11) Enable HMI Ethernet in [Project Settings];
12) Set PLC IP in [Device IP] settings;
✎Note:
1) The S7-1200 supports simultaneous connection of three devices, so the driver supports simultaneous access to PLC by three touch screens.
2) HMI access PLC, use S7 protocol, access PLC TSAP 02.01 (s7-1200 PROFINET interface only supports three connections, the default support), detailed reference to the system manual of S7-1200.
PLC settings
1) Add BD
Please uncheck [Symbolic access only] option;
2) Address settings, using BD2 as example.
DB×DBB2xxxx, DB×DBW2xxxx, DB×DBD2xxxx for accessing data of DB2 in B1.
2 represent DB block number
xxxx represent address
Such as:
DBxDBB20000 = DB2.DBB0
DBxDBW20004 = DB2.DBW4
