MHJ

Requirements

  • MHJ Edition or Ultimate Edition
  • WinSPS-S7, WinPLC-Engine or Grafcet-Studio

This driver allows Factory I/O to be used together with WinSPS-S7 and WinPLC-Engine, which are low-cost alternatives to official Siemens software. Additionally, you may use Grafcet-Studio which allows you to design and execute grafcet charts.

WinSPS-S7 is a PLC programming tool for S7 PLC with a built-in PLC simulator (S7-300/400). WinPLC-Engine is a S7-300 PLC simulator that can be programmed with STEP7 V5.x and TIA Portal V1X. Grafcet-Studio is a tool for designing and executing controllers specified in Grafcet.

Configuration

Factory I/O will automatically detect WinSPS-S7, WinPLC-Engine or Grafcet-Studio. Check how to setup WinSPS-S7, WinPLC-Engine and Grafcet-Studio for Factory I/O:

Grafcet Studio

In order to correctly export tags to Grafcet-Studio you must set WORD Inputs / WORD Outputs to 256.

Configuration Setting Description
Bit Inputs Defines the memory address offset and the number of digital inputs to use (max 256).
Bit Outputs Defines the memory address offset and the number of digital outputs to use (max 256).
WORD Inputs Defines the memory address offset and the number of WORD inputs to use (max 64). These are used to write floating and integer values to WinSPS-S7 or WinPLC-Engine.
  • Floating sensor values ranging from -10 V to 10 V are linearized between -27648 and 27648 and sent as integers into a Word.
  • Floating sensor values ranging from 0 V to 10 V are linearized between 0 and 27648 and sent as integers into a Word.
WORD Outputs Defines the memory address offset and the number of WORD outputs to use (max 64). These are used to read floating and integer values from WinSPS-S7 or WinPLC-Engine.
  • Floating actuator values ranging from -10 V to 10 V are expected linearized between -27648 and 27648 and encoded as integers.
  • Floating actuator values ranging from 0 V to 10 V are expected linearized between 0 and 27648 and encoded as integers.
