Lauer PCS Series Operation Console Configuration Guide

Node number feedback in W6 digits 8-15

4.2 Variable Editing Rules

Preset value modification: Press the number keys to enter, press ENTER to confirm writing to PLC

Offset input: such as "10+" (adding 10 to the existing value), only applicable to BCD and BIN variables

CLR key: Restore to last read PLC value

BIT and CSTRING: Write immediately after modification without the need for ENTER

Write verification: PCS will read the PLC twice, compare the written value with the read value, and issue a warning if there is a discrepancy

4.3 Preset value status feedback

W8: High byte=last modified preset value word address; Low byte=number of bytes written (0=BIT variable, 2=16 bits, 4=32 bits)

W9: Bitmask, indicating which bit in the BIT variable has been modified

Message management and priority

5.1 Priority Level

PCS adopts 7-level priority management, and low priority can be interrupted by high priority:

Priority name triggering method

0 (minimum) default text displayed when there are no other activities

2 Menu PLC writes menu number through W14

Triggered by 4 information message bits, with the attribute of "information"

6 warning message triggered, attribute is "Warning"

8 fault message bit triggered, attribute is "fault"

12 Help Press HLP Key

Highest communication error interface or startup test error

5.2 Message Configuration

128 message bits (W15~W22), corresponding to 128 message texts

Each message can be individually configured with priority (information/warning/fault) and deletion mode (1-4)

Delete Mode 1: PLC Reset Message Bit Clears

Delete Mode 2: Manually press CLR to clear and reset PLC bit at the same time

Delete Mode 3: Manually press CLR to clear (without resetting PLC bit)

Delete Mode 4: Clear CLR only when PLC bit has been reset

5.3 Display and Storage Behavior

PLC can control the display and storage behavior of messages through W12:

Display mode (W12 bits 8-10): 0=static, 1=flashing

Storage mode (W12 bits 0-5): 00=first message (no manual selection), 01=first message (can be manually selected), 10=last message (no manual selection), 11=loop display

Function keys and LED control

6.1 Button Status (W4~W5)

When the button is pressed, the corresponding position is 1

PCS 009/090：F1~F8（W4）， Control key (W5)

PCS 095/095.1: Additional F9~F16 (W23 high byte)

6.2 LED Control (W10~W11, W24~W25)

Each function key is equipped with green and yellow LEDs (PCS 009 only green). Each LED is controlled by two bits for status:

Wx bit Wx+1-bit LED status

0 0 OFF

0 1 anti flicker (25% bright)

1 0 ON

1. Blinking (75% bright)

6.3 System Status LED

? (Input request): Waiting for key operation

! (Menu/Message): Display Information/Warning/Fault

ERR (Communication Failure): Constant light=Communication not started, flashing=Communication interrupted

PCSPRO configuration and debugging process

7.1 Configuration steps

Running PCSPRO on PC (MS-DOS/DR-DOS environment)

Define variables (select format, address, text, limit values)

Create text (default text, menu text, message text, help text)

Configure menu structure (node connections, operation text allocation)

Select PLC driver (corresponding to PLC brand and protocol)

Generate data records and download them to PCS (using PCS 733 cable)

7.2 DIL switch setting

DIL function

1~4 PLC bits available to users (W4.4~W4.7)

5-6 driver configuration parameters (baud rate/interface selection)

7 programming baud rates (ON=115.2k, OFF=38.4k)

8 operating modes (OFF=normal operation, ON=stop)

9 EEPROM write protection (ON=writable, OFF=write protected)

10 Contrast Adjustment (ON=Adjustable, OFF=Locked)

Important: After programming, be sure to set DIL9 to OFF, otherwise data storage may not be guaranteed.

7.3 Common Fault Diagnosis

SYS LED is constantly on: The device is in offline or configuration mode. Possible cause: The configuration cable PCS 733 is still connected, and the DTR level on the PC side makes DSR effective

ERR LED flashing: Communication established but interrupted, check cable and DIL5/6 configuration

Message not displayed: Confirm that the message bit is within the range of W15~W22, and W13 bits 0~3 allow the corresponding message word to be transmitted

The preset value cannot be modified: Check if W14 bit 7 (NOMINAL-P editable) and whether the variable is defined as NOMINAL/NOMINAL-P

PCS 095.1 Additional Features

8.1 Offline menu and data recording switching

Press HELP+CLR to enter the offline menu

Use the+/- keys to select data records (0-3), press ENTER to confirm and reset

DIL11 and DIL12 determine the selection of data recording after power on

8.2 Printer Functions

PCS 095.1 has a built-in printer interface that supports:

Hard copy: W13 bit 12 rising edge trigger, print current screen content

Message printing: W13 bit 13 set to 1 enables message printing queue

Internal variable configuration: timeout (ZA), interface selection (ZB), handshake protocol (ZC), output direction (ZD), baud rate (ZE), data bits (ZF), stop bits (ZG), checksum (ZH)
