LAUER for the operating consoles PCS 009, PCS 090, PCS 095, PCS 095.1

LAUER для операционных консолей PCS 009, PCS 090, PCS 095 и PCS 095.1

The operating consoles PCStopline offer the highest degree on perfection, unparalled in design and function. PCStopline keeps every thing under control - from the PCSmini to the PCSmaxi, with a superior operating culture and an unlimited setup freedom. PCS, the first programmable operating console with a large selection of "ready-to-use" opera ting functions or operating tools which are simply selected via instructions. You can realize even the most unuasal operating requests at ease and in a minimum of time.

n Machine operation using 8 (PCS 009, PCS 090) or 16 (PCS 095, PCS 095.1)

 freely assignable keys. These F01 to F08/F16 labeled keys can be application

 specifically inscribed and are provided to the controller as status bits.

 n Machine operation using 4 (PCS 009), 16 (PCS 090) or 32 (PCS 095, PCS

 095.1) freely usable LEDs. These can be assigned the indicating states ON,

 DARK, FLASHING, and INVERSE FLASHING. A green and a yellow LED is allocated

 to each function key.

 n Display of fixed texts with integrated variable values. The values can be

 represented selectably as numerical values or in text format.

 n Representation of the contents of 233 words as variables. In addition, 650

 external variables can be defined. 9 variable formats (from bit to timer) are

 available.

 n 3 text groups, 128 operating texts as menu and idle texts, 128 message texts

 with up to 332 lines, 5 help texts with up to 32 lines.

 n 127 menus with 255 menu nodes each for any menu configurations.

 n 4 different deletion modes. For every message, 1 of 4 possible deletion modes

 can be selected.

 n Modification of the content of any word within the transfer area. Using the

 integrated editor all possible representation formats can be setup.

 n 7 priority levels for idle text up to help text, 3 message priorities Information,

 Warning, Fault. This working-condition related management significantly off

loads the programmable controller program.

 n Monitoring of rising or falling edges of 128 consecutive bits. The assignment

 of texts, the manage-ment of 3 priority levels (Information, Warnings, and Faults),

 keeping the timely sequence as much as possible, organization of the FIRST

 MESSAGE, LAST MESSAGE, and CYCLIC DISPLAY, the individually settable dele

tion behaviour, and the representation formats NORMAL and FLASHING are tasks

 which are managed by the PCS by itself.

 n Communication monitoring (wire-break, short circuit). A very efficient data

 transfer is secured by the integrated priority management in connection with the

 intelligent package length optimization, the high thruput rate and the fault tole rance.

The simple communication principle of the PCS

Communication between any PLC and the PCS occurs as follows: The PCS writes in predetermined word areas of the PLC, functions or nominal values, which the PLC then reads and interprets. The PLC writes in predetermined word areas functions or actual values, which are automatically read and interpreted by the PCS. Independently of the PLC there are maximum 256 words of 16 bit, that is to say 4096 inputs / outputs for the PCS/PLC communication available.

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 n Information n Warnings n 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

The Variables of the PCS 009, PCS 090, PCS 095, PCS 095.1

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 varia bles (freely definable) and 6 internal variables are supervised from the PCS.

The BIT variable ON OFF STOP UP 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 

STRING variable DOWN Version 5 06/95 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

BCD variable: BCD-1, BCD-2, BCD0-1, BCD0-2

The nominal value of the BCD variable corresponds to that of a BCD thumbwheel switch and the actual value to that of a BCD digital display. The 4 digit (decimal positions) variable BCD-1 is allocated to a word, the 8 digit variable BCD 2 to two consecutive following words 32 bits (W n, W n+1). BCD variables are displayed without pre-zeros. For example a BCD 2 actual value is: 4 2567. The 4 digit variable  BCD0-1 is allocated to a word, the 8 digit variable BCD0 to two consecutive following words 32 bits (W n, W n+1). BCD0 variables are displayed with pre-zeros. For example the actual value of a BCD0 is: 0004 2567 Every BCD value is limited to a min/max value. Example: The batch size per window type is written in word 30 as a 4 digit nominal value without min/max limits. BCD CODED 4 + 3 + 2 + 1 +–––––– The nominal value input "8500" takes place with the ten key keyboard of the PCS and is transfered to the word with the ENTER BCD coded key

BINARY variables: BIN-1, BIN-2, BIN-A, BIN-B, VBIN-1, VBIN-2, VBIN-A, VBIN-B, BIN0-1, BIN0-2, BIN0-A, BIN0-B, VBIN0-1, VBIN0-2, VBIN0-A, VBIN0-B

The nominal value of the BIN variable corresponds to that of a BIN thumbwheel switch and the actual value to that of a BIN digital display. The scaled 16 bit variables (BIN-1 to VBIN-A) are allocated to a word, the 32 bit variables (BIN-2 to VBIN-B) to two consecutive following words (W n, W n+1). The variables (V)BIN(0)-1,2 only differ from those of the (V)BIN(0)-A, B in the way the characters are loaded (V)BIN0-1,2 and (V)BIN-1,2 are with and without pre-zeros repectively VBIN(0)-1,2A,B take the operational sign into consideration. Every (V)BIN variable is limited by a min/max value. In addition the (V)BIN-1,A variables can be scaled. Example: The temperature of the engine brake can be set between 0°C and 70°C. The scaled 16 bit nominal value is written into the word W 45 with a min/ max limit. Example: The window height is adjustable between 750 mm and 1500 mm. The 32 bit nominal value is written into the word 41+42 with a min/max limit. The higher value part remains in W 41, the lower value part in W 42.

WORD variable

The WORD variable is specially suitable for service. Die Darstellung kann sowohl bitweise (KM), hexadezimal (KH) oder byteweise dezimal (KY) erfolgen. An alteration of the bit pattern with the PCS is possible if the WORD variable is defined as a nominal value. WORD VARIABLE BIT CONFIGURATION     DATA VALIDITY 00001101     11001110 TIMER VARIABLE TIMER 235.1 Version 5 06/95 Example: The word 33 is to be displayed and altered in the PCS display: Alteration of the nominal value WORD variable takes place in a menu. Display line 1 Display line 2 BIT PATTERN OF WORD 33 0000000000000101 The value of the WORD variable can be changed with the "0" or "1" key. The "+" key switches the pointer one place to the right and with the "–" key, one place to the left. Display line 1 Display- line 2 BIT PATTERN OF WORD 33 1111000011000000 The ENTER key puts the new value into the word

TIMER variable

The TIMER variable allows an input of a 3 digit numeric input (BCD) and a timebase value with 4 selection (displayed as text). Example: Word 100 should be displayed in Timerformat. The content of word 100 is KH1235. If the timebase is defined as ".0", ".1", ".2" and ".3" in the display "235.1" is visible. The value is defined with the key "0"..."9". The selection between base and value is done with the (.) key. The timebase is selectable with + or - key or direct input with "0" bis "3" key

ASCII variable

If an alphabetical nominal value is required (article number, name etc.) the ASCII variable provides it in a simple manner.
