5.4 Register description
The registers can be read or written via the register communication. They are used for the parameterization
of the terminal.
General description of registers
Complex terminals that possess a processor are able to exchange data bi-directionally with the higher-level
controller. These terminals are referred to below as intelligent Bus Terminals. These include the analog
inputs (0 to 10 V, -10 to 10 V, 0 to 20 mA, 4 to 20 mA), the analog outputs (0 to 10 V, -10 to 10 V, 0 to
20 mA, 4 to 20 mA), serial interface terminals (RS485, RS232, TTY, data exchange terminals), counter
terminals, encoder interfaces, SSI interfaces, PWM terminals and all other parameterizable modules.
The main features of the internal data structure are the same for all the intelligent terminals. This data area is
organized as words, and includes 64 memory locations. The important data and parameters of the terminal
can be read and set through this structure. It is also possible for functions to be called by means of
corresponding parameters. Each logical channel in an intelligent terminal has such a structure (so a 4-
channel analog terminal has 4 sets of registers).
This structure is divided into the following areas:
