Standard I/O devices
The standard I/O devices such as process monitor, process operation keyboard, configuring keyboard, mini floppy disk unit, logging printer and message printer are described in Section 5.
The interface modules for operation channel generate the RGB signals for the process monitors. They also have three
No operation channel interface modules are essential if the
AS 235 H is always operated and configured centrally. However, the use of an interface module is recommended for diagnostics. The operation channel interface modules must be ordered together with the standard devices.
In contrast to the AS 235 system, the process monitors, key- boards and printers in the AS 235 H are not directly connected to the operation channel interface module. The process motors are connected to the operation channel interface modules of the two partial systems via video relays. A video relay is assigned to each operation channel. The video relays ensure that the con- nected process monitors always display the same screen con- tents. The process monitors are connected to the active partial system when transferring to asynchronous operation. The video relays are also connected to the synchronization modules for this purpose.
The signal cables of the keyboards and printers are connected to the operation channel interface modules of the two partial sys- tems via distribution cables.
The keyboard and printer distributors as well as the video relays are components of the parts set for operation channel switch- over which belongs to the delivery of an operation channel.
An additional printer distributor is required if a second printer is to be connected to an operation channel, and must be ordered separately (option).
Possible connections and a summary of connecting cables: see page 3/29 ff.

Extension units
Depending on the complexity of the automation function, the capacity of the AS 235 H can be increased up to max. 91 slots for I/O modules by the addition of up to 7 extension units.
The extension units EE1 to EE3 are connected to the basic unit via 2 separate, redundant I/O buses 1 (A). Each of these buses is connected to the CPU of an AS 235 H partial system via a sep- arate interface module for I/O bus 1 (A). These extension units are fitted in the basic cabinet.

Automation systems
AS 235 H
Basic cabinet
Extension units EE4 to EE7 are fitted in the extension cabinet. These are also connected to the CPU of an AS 235 H partial sys- tem via 2 separate I/O buses 2 (B) which are redundant to one another, each of which has its own interface module for
I/O bus 2 (B).
An extension unit of the AS 235 H automation system consists of a subrack with slots for 13 I/O modules, I/O bus comparator and switchover module, and a DC 5 V power supply module.
When ordering the extension units it is possible to select whether the extension unit EE1 is to be delivered on its own, together with EE2, or together with EE2 and EE3.

The extension units are supplied directly with DC 24 V from the power supply subrack. Each extension unit is fused separately with 16 A on the power supply subrack. The DC 5 V supply is taken from the power supply module DC 5 V.

I/O modules
The I/O modules are the process interface of the AS 235 H auto- mation system. They comprise signal modules and function modules, including calculation modules. See Section 4 for the properties, functions and Ordering data of the I/O modules.
Up to 13 I/O modules can be inserted into each of the extension units (max. 3) of the basic unit. Please observe the max. thermal loading (see standard cabinets and accessories, page 3/23).
A further 52 I/O modules can be inserted into an additional extension cabinet with up to 4 extension units, thus enabling a total of 91 I/O modules per AS 235 H system.
One ES 100 K extension system can additionally be connected per I/O bus 1.
During planning it should be noted that the 16 A with which each extension unit is fused must not be exceeded.
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.
