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

The central processor divides the RAM and differentiates access operations to

•the 1-Mbyte system RAM with battery backup for all fixed system data and programs,

•the 4000-Kbyte RAM with battery backup for all user programs and data and for variable system data, and

•the transfer memories of the interface modules for I/O bus, operation channel, mini floppy disk unit and local bus.

The memory module with Error Detection and Correction EDC can correct a 1-bit error when reading, and eliminate it in the memory cell together with the system software.

The interface module for I/O bus establishes the connection between the 8-bit central unit bus and the I/O bus. One or two of these modules can be plugged into the basic system of the AS 235 K:

•The interface module for I/O bus 1 (A) supplies the I/O modules plugged into slots 1 to 5 of the basic system and/or the inter- face modules for the ES 100 K extension system. It is always required.

•The interface module for I/O bus 2 (B) is only required if slot 6 in the basic system is to be used. It must be ordered as an option.

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 20-mA current loop interfaces to which the process operation keyboard PBT or the configuring keyboard and 2 print- ers (logging and message printers) can be directly connected.

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.

• Coding, inserting and labelling	6DS5 705-8AA
for 1 I/O module

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 20-m local bus (each bus converter Ul counts as 1 par- ticipant). The total length of the connecting cables must not exceed 20 m.

1)This cable is only suitable for connection to the process operation key- board or the signal distribution unit. A cable 6XV2 167-8B.. (order sepa- rately) is required for the direct connection to the basic unit of the

AS 235 K system (operation channel).

2)Interface module for operation channel 1 is included in the basic system.
