Modbus TCP Register Map
The following chapter shows how to generally access data of the FBP-devices connected to
port one to port four of the MTQ22-FBP.
Information
Modbus TCP counts registers beginning with one. But on the bus registers start
counting from zero. The addresses in this manual describe the addresses that are
transmitted on the network. Depending on your client application it might be nec-
essary to increment all addresses by one.
The I/O-data as well as diagnostic and configuration data of the connected PSE devices can
be accessed applying the supported Modbus function codes. The supported functions can be
found in respective sub section.
