Page 3: Introduction
Parallel Message Display INTRODUCTION CET message display units are diagnostic devices equipped with an alphanumeric display, which shows a series of written information relative to particular situations for the operator. The information is given under the form of messages, which can have a length up to 80 characters with the possibility to arrange explanatory sub-texts, scrolling messages, flashing messages and other highlighting modes. -

Page 6: Functional Description
CET s.r.l. Parallel Message Display FUNCTIONAL DESCRIPTION 2.1. FUNCTIONING AND USE The functioning of the devices is relatively simple: • upon power-up, lack of input signals, MESSAGE NO. 0 is displayed. • the signals to make up the code of the message to be recalled are sent to the display unit input through the PLC;... -
Page 7: Chart Of Commands
CET s.r.l. Parallel Message Display 2.2. CHART OF COMMANDS Input signals are divided and managed according to the codes reported in the following chart: COMMAND TYPE 0 IMP. Binary message recall + Synchronism IMP. BCD message recall + Synchronism TYPE 1 TYPE 2 IMP. -
Page 8: Command Type 1: Bcd Message Recall + Synchronism
CET s.r.l. Parallel Message Display This coding requires entering the message recall number in BINARY code: Number in the range 0 to 512 Coding and number are always read at the variation 0 1 of synchronism signal SY. 2.3.2. Command TYPE 1: BCD message recall + Synchronism... -
Page 9: Command Type 8: Continuous Message Recall In Binary Code
CET s.r.l. Parallel Message Display The display unit reads the 9 inputs as direct contacts and the closure of each of them causes the associated message to be displayed, The message disappears when the input reopens. In case of several inputs closing at the same time, the display unit shows the message associated to the lower input from D0 to D8, with priority to D0. -
Page 10: Command Type 13: Sub-Message Display In Bcd Code
CET s.r.l. Parallel Message Display 2.3.6. Command TYPE 13: Sub-message display in BCD code Using this command, you can recall a message to the second display line together with the message that is already displayed at the moment. This enables two different messages being displayed at the same time. Should one or both messages be longer than 20 characters, the text will automatically scroll from right to left. -
Page 11: Command Type 3: Address In Bcd Code
CET s.r.l. Parallel Message Display 2.4.1. Command TYPE 3: Address in BCD code Inputs Command TYPE 3 This code informs the display unit that the first 8 inputs represent the position address (0 to 80) in BCD code where the next variable will be laid. -
Page 12: Command Type 5: Variable In Ascii Code
CET s.r.l. Parallel Message Display This code identifies a BCD variable in the first 4 inputs and a service BINARY value in the second 4 inputs, as shown: SERVICE BITS Number in BCD code in the range 0 to 80 All values are read at the 0 1 variation of the synchronism signal SY. -

Parallel Message Display Using this coding, you can set the system language and message bank you are to work with. Upon power-up and with the A, B, C and D commands set, the display unit automatically reads the system language and message bank.

CET s.r.l. Parallel Message Display 3.1.2. Using inputs in NEGATIVE logic DISPLAY UNIT LOGIC UNIT GND-EARTH C = Collector E = Emitter 3.1.3. Input command timing Generally, in order to be read, each device input should remain in stable conditions for at least 5 msec. -
Page 17: Serial Line
CET s.r.l. Parallel Message Display 3.2. SERIAL LINE All models are equipped with a RS232 serial line with fixed protocol: 1 START Bit, 8 DATA Bits, Parity NONE, 2 STOP Bits with transmission speed of 19200 BAUD (except transmission to printer which is executed at a speed of 1200 BAUD). -
Page 18: Programming The Devices
CET s.r.l. Parallel Message Display PROGRAMMING THE DEVICES All message display units of this series can be programmed exclusively through the serial line using a personal computer. The message display units must be powered during programming. 4.1. PROGRAMMING USING A PERSONAL COMPUTER It is necessary to use the special software package named WINTEXT, which, by means of guided logic menus, allows the generation of all necessary messages. -

PRINTER ST40 CET message display units can control the special printer " ST40 " through the serial line RS232. This printer is a panel printer housed in a DIN 144 x 144 box and complete with a multi-voltage mains power unit. Printing is impact dot-matrix type and on 40 columns using standard paper. -
Page 20: Installation
To programme CET message display units, it is necessary to use the special software package "WINTEXT" supplied by CET. A broad and accurate operational description is available in the software in-line HELP file. For use with the message display units, select the device to be programmed in the list prompted by the software menu. -
