S5-115F Manual Installation Guidelines
3.3.5 Simulator
You can use an appropriate simulator instead of a front connector. Use the toggle switches on the
front of this device to simulate input signals ( Figure 3-29). A simulator needs an external power
supply.
Simulators can not be used for mixed digital input/output modules or for output modules.
