5.9.10 Pro-RSxxx Rev. A
The Pro-RSxxx module has 2 or 4 interfaces of the type RS-232 or RS-485.
The names for the module types are shown in the table below:
All modules of the RSxxx-y modules are equipped with the "Quad Universal
Asynchronous Receiver/Transmitter" (UART) controller, type TL16C754 from
Texas Intruments
®
. Functionality and programming of the interfaces are based
on this controller.
The physical difference between the interface versions is their signal level,
which is provided by appropriate drivers on the bus.
The Pro-RS-xxx-4 module with 4 serial interfaces requires 2 module
addresses. Therefore the module a1 is set additionally to the module’s
base address set manually. By software, the module is addressed via the base
address only.
