Siemens S7 Adapter

ISO-on-TCP communication with S7-300, 400, 1200, and 1500 PLCs.

SIEMENS_S7 uses in-process ISO-on-TCP (nodes7 syntax) to read PLC addresses.

Connection config

FieldDefaultDescription

port102ISO-on-TCP port

Tag addresses (nodes7)

Examples:

DB5,REAL10
DB5,INT0
DB5,X0.0

Data type may be inferred from S7 address when not set explicitly.

Tips

  • Duplicate connection detection uses host + port + rack + slot
  • Use Test connection before bulk tag import
  • Import tags via CSV on the device detail page
