... and rapid set-up of a particular operational requirement

1 First define the specification and decide on the required PCS (PCS micro, PCS

mini, PCS midi or PCS maxi)

2 Allocate the word and bit number to variables (actual- and nominal values).

3 Create the texts for operational guidance and help functions as well as for

displays of machine conditions.

4 Determine the message texts and apply these words to them, subdivide the

message texts into 3 priority groups

■ Information

■ Warnings

■ Faults

and take into consideration the differing cancel modes, display and message

modes. Display and message modes can be altered by the PLC at any time.

5 Define the menus and the menu operating texts.

6 Transfer the data file (variables, texts, menus) which was made in the PC or PG

under MSDOS/DRDOS or compatible DOS-system, with the software PCSPRO

into the PCS.

7 Implement and parameterize the PLC specific operating software (PCS 91.nn,

see overall view of information) in the users' programme.

8 Connect the PCS via the adapter cable with the PLC. Test together the operation

and control of the PCS and PLC and adjust if necessary

Machines produce different parts. Therefore quick and selective alterations of finished

sizes and functions (variables) are especially important for increased flexibility.

The PCS features a convenient method of processing the variables. 650 external variables (freely definable) and 6 internal variables are supervised from the PCS.

The value of the external variables are stoped in the words

30...255. The PCS differentiates

between actual values and nominal values:

ACTUAL: The value in the word

is the actual value. The PCS can

only display the value.

NOMINAL: The standing value

in the word is the nominal value.

The value can be displayed and

changed by the PCS.

NOMINAL VALUE-P: The private value in the word is a nominal value. The PCS can display

the value. It can be changed only

if this is allowed by the word 14

bit 7 = log 1 (key switch or DILswitch 1...4 on the rear side of

the PCS). When the bit 7 of word

14 = log 0, the display of the

actual value follows.

The BIT variable

When two possibilities can be selected at an input, the descision is taken by the bit

variable. This is in the form of an ON/OFF switch.

Every switch position represents an inscription (text) which appears in the display.

Each bit variable occupies a bit. A data word can also take on up to 16 differing bit

variables or switches.

Example: A wood shavings vacuum absorption cleaner shall be switched on or off

in bit 2 data word 33.

The +/- switch selects the inscription or the switching position. The bit bears the value

of the inscription. The first inscription carries the value log 0, the second bears the

value log 1.

STRING variable

When two or more possibilities can be selected at an input, the decision is made by

the STRING variable. It corresponds to a selector switch.

With STRING variables, every switch position is classified with an inscribed text, which

appears in the display. Every STRING value carries a data word with up to 256 switch

positions. The switch position is deposited in low bytes of the data word.

Example: The frame material shall be selected in data word 40.

The inscription or switching position is selected with the +/- key. Acceptance follows

with the ENTER key.

CSTRING variable

The CSTRING variable corresponds to STRING variable. Acceptance follows directly

after using the +/- key without ENTER.
