Siemens S7-PLCSIM

Requirements

  • Siemens Edition or Ultimate Edition
  • Siemens S7-PLCSIM V5/13-16/Advanced v3.0

This driver provides connectivity with Siemens S7-PLCSIM. It can be used to control Factory I/O with S7-PLCSIM v5/13-16/Advanced through TIA Portal.

TIA Portal Template Projects

Note that you must use a TIA Portal template project when connecting with S7-PLCSIM v13-16. Without these templates, Factory I/O will not be able to communicate with this particular version of S7-PLCSIM.

Configuration

siemens s7-plcsim configuration

Auto connect Periodically tries to connect to the PLC.
Model

PLC model: S7-300, S7-1200, S7-1500 or S7-1500 (S7-PLCSIM Advanced).

S7-PLCSIM Advanced must be configured with an instance name set to factoryio. You can change the instance name with the console command drivers.siemens_s7plcsim.instance_name = 'newname'.

Numerical Data Type Choose whether WORD or DWORD will be used for analog values.
Bool Inputs Address offset and number of Bool inputs to use for digital sensors (max 256).
Sensors' values are written into I memories starting at address 0 (by default).
Bool Outputs Address offset and number of Bool outputs to use for digital actuators (max 256).
Actuators' values are read from Q memories starting at address 0 (by default).
DWORD Inputs Address offset and number of DWORD/WORD inputs to use for analog sensors (max 64).
DWORD Outputs Address offset and number of DWORD/WORD outputs to use for analog actuators (max 64).

About Analog Values

You should be aware of how floating and integer values are exchanged between Factory I/O and the PLC. The driver can be configured to read/write values using WORD or DWORD and the following list gives you detailed information on how data is encoded/decoded in both cases.

DWORD Inputs (Sensors)

  • Floating sensor values are encoded as 32-bit floating point numbers (REAL).
  • Integer sensor values are encoded as 32-bit integers.

DWORD Outputs (Actuators)

  • Floating actuator values are expected as 32-bit floating point numbers (REAL).
  • Integer actuator values are expected as 32-bit integers.

WORD Inputs (Sensors)

  • Floating sensor values ranging from -10 V to 10 V are linearized between -27648 and 27648.
  • Floating sensor values ranging from 0 V to 10 V are linearized between 0 and 27648.
  • Integer sensor values are converted into signed 16-bit integers.

WORD Outputs (Actuators)

  • Floating actuator values ranging from -10 V to 10 V are expected linearized between -27648 and 27648.
  • Floating actuator values ranging from 0 V to 10 V are expected linearized between 0 and 27648.
  • Integer actuator values are expected as signed 16-bit integers.

When using WORD, conversion between integer values and real number values can be done with the 'SCALE_X' and 'NORM_X' instructions.
