The I/O modules are the process interface of the AS 235 K. They comprise signal modules and function modules, including cal- culation modules. See Section 4 for the properties, functions and Ordering data of the I/O modules.
The AS 235 K has slots for 6 I/O modules. Slots 1 to 5 are con- nected to the central processing unit via I/O bus 1 (A). Slot 6 is connected to I/O bus 2 (B). As a result, the interface module for I/O bus 2 must be inserted if slot 6 is to be used.
The number of slots for I/O modules can be increased up to a maximum of 108 by connecting up to eight ES 100 K extension

Standard I/O devices
The standard I/O devices such as process monitor, process operation keyboard, configuring keyboard, mini floppy disk unit and logging/message printers are described in Section 5.
The interface module for operation channel generates the RGB signals for the process monitors, including the CVS signal. It also has three
See page 3/29 for possible connections of standard I/O devices and a summary of connecting cables.
The interface module for operation channel 1 belongs to the scope of delivery of the basic system and is always required. A second interface module is only required if 2 operating con-
systems.
The I/O modules can be supplied coded, inserted and with labelled slots. Arrangement, designation and connection dia- grams (including address data) are required from the orderer.

Interface module for ES 100 K
The interface module for the ES 100 K links the I/O bus of the AS 235 K basic system to the I/O bus of the ES 100 K via a cable. Interface modules are required in both the AS 235 K basic sys- tem and the ES 100 K extension system.
The interface module for the ES 100 K can be inserted into any slot for I/O modules in both the AS 235 K and the ES 100 K.
A maximum of four interface modules for a total of four ES 100 K extension systems can be plugged into slots 1 to 5 in the
AS 235 K.
The I/O bus 2 (B) only supplies slot 6. Therefore a further four ES 100 K extension systems can be connected serially to the interface module inserted there. The use of slot 6 requires that the interface module for I/O bus 2 (optional accessory) is inserted.
Bus components
The TELEPERM M systems can communicate with one another via the CS 275 plant bus up to distances of 20 m (local bus) or
4km (remote bus). The local bus is redundant as standard. The remote bus can be redundant as an option.
Up to 9 participants can be interconnected as a local bus island via the
