The device address is composed like following:
Important:
If the PLC address is defined at the Topic level, it can be omitted in the Tag definition. In that case the Tag name will only contain
the "ValueName".
If the PLC address is specified at the Topic level, it will replace any address defined Tag by Tag.
note:
For an S7-300, it’s generally always 03.02 .
For an S7-400, you have to take into account the slot number of the CPU.
For example if the CPU is on slot 4 rack 0 use TSAP 03.04, if the CPU is on slot 5 rack 1 use TSAP 03,25.
MPI
MPI, MPI node address
node address: MPI node address of the PLC
Reach by MPI the PLC with the node address 2
PROFIBUS, Profibus node addr
node address: PROFIBUS node address of the PLC
Reach by Profibus the PLC with the node address 9
ISOTCP
ISOTCP, IP address, CalledTSAP
IP address : IP address of the PLC (ex: 10.0.120.204)
Called TSAP : Transport Service Access Point (ex: 03.02)
Reach by ISOTCP the PLC at IP 10.0.120.204 with the TSAP 03.02
ISOTCP, IP address, CalledTSAP,
Subnet ID, MPI node address
IP address : IP address of the PLC (ex: 10.0.120.204)
Called TSAP : Transport Service Access Point (ex: 03.02)
Subnet ID : ID of the MPI subnet
MPI node address : address of the PLC
