3.2 Register description

The complex terminals can be adjusted to different operating modes or

functionalities. The General Description of Register describes the contents

of the registers, which are identical for all complex terminals.

The terminal-specific registers are explained in the section following to it.

The access to the internal registers of the terminal is described in the

section Register Communication.

3.2.1 General register description

Complex terminals that possess a processor are capable of bidirectionally

ex-changing data with the higher-level control system. Below, these

terminals are referred to as intelligent bus terminals. They include the

analog inputs, the analog outputs, serial interface terminals (RS485,

RS232, TTY etc.), counter terminals, encoder interfaces, SSI interfaces,

PWM terminals and all other parameterizable terminals.

Internally, all intelligent terminals possess a data structure that is identical

in terms of it's essential characteristics. This data area is organized in

words and embraces 64 registers. The essential data and parameters of

the terminal can be read and adjusted by way of the structure. Function

calls with corresponding parameters are also possible. Each logical

channel of an intelligent terminal has such a structure (therefore, 4-channel

analog terminals have 4 register sets.
