16.1 Getting Started
16.1.1 Features of XG-SIM
XG-SIM is a Windows-based virtual PLC for XGT PLC series. If using XG-SIM, an operator may execute a created program without
PLC and debug a PLC program by using the functions of input setup and module simulation.
XG-SIM supports the following functions.
1) Program simulation
An operator can simulate a program created by LD/SFC/ST languages. In addition, it supports modification function during run, with
which an operator may apply modification during run of a program that is operated in XG-SIM, and it supports debugging function
that trace a user-created program by unit of step.
2) PLC Online function
Besides program monitoring function provided by XG5000, an operator may user online diagnosis functions such as system monitor,
device monitor, trend monitor, data trace and user event.
3) Module simulation
It also supports simple simulation function for modules mountable on XGK rack type PLC, such as digital I/O module, A/D
conversion module, D/A conversion module, high speed counter, temperature control module and positioning module. If using the
module simulation function, a program may be simulated by using input values from module.
4) I/O input condition setup
The value of device may be set with value of specific device or channel value in a module set as input conditions. Using I/O input
condition setup function may realize the program simulation as created with no PLC program separately created to test a created
PLC program.
