Using S500 I/O Modules

The S500 I/O modules could be used either directly connected to an AC500 CPU (central expansion) or
together with an FBP Interface Module DC505-FBP + an FBP (PROFIBUS DP, DeviceNet, etc.) as
decentralized expansion.

Introduction to AC500
The AC500 modules are not designed for removal or insertion under power.
Because of unforeseeable consequences, it is not allowed to plug or unplug
modules with the power being ON.
Disconnecting the FBP or any powered modules while energized in a
hazardous location could result in an arc, which could create a flammable
ignition resulting in a fire or explosion.
Be sure that power is removed and that an area has been thoroughly checked
to insure that flammable materials are not present prior to proceeding.
