12 1.5 PARALLEL INTERFACE -TEXT DISPLAY... -THE PARALLEL INTERFACE The parallel nterface s the most mportant connecton between the machne (control) and the text dsplay. All essental functons of the are operated by ths nterface. In detal t s the followng: - call up of up to 511 messages BIN-coded or up to 199 messages BCD coded - handshake (STROBE and ACKNOWLEDGE) - handlng of the message - nput of external varable data BIN = CODED MESSAGE NUMBER STROBE = WITH THE STROBE THE MESSAGE TEXT OR MESSAGE TEXT PAGE IS CALLED UP (RISING EDGE 0 --> 1 * ) ACKNOWLEDGE = EACH STROBE IS FOLLOWED BY ACKNOW- LEDGE (FALLING EDGE 1 --> 0 * ) VARIABLE DATA = SWITCH OVER FROM MESSAGE NO.

OFF / STROBE = ACTIVATED MESSAGES ARE SWITCHED OFF ACCORDING TO STROBE MOD FIRST FIRST MESSAGE = THE FIRST MESSAGE IS DISPLAYED, FOLLOW-ING ARE REGISTERED MOD LAST LAST MESSAGE = THE LAST MESSAGE IS DISPLAYED, OTHERS ARE REGISTERED SPARE = INPUT WITHOUT FUNCTION OFF / DIRECT = ALL ACTIVATED MESSAGES ARE SWITCHED OFF IMMEDIATELY *) 0 = LOG 0 (0Vdc), 1 = LOG 1 (24Vdc) **) DIRECT OR CYCLIC DIPLAY

13 1.6 SERIAL INTERFACE -TEXT DISPLAY... -THE SERIAL INTERFACE By the seral nterface RS 232 (TTY) the text dsplay LCA 245 can be programmed or the complete content of one can be transfered nto another. Also the connecton of a text montor LCA 180 for a second text output s possble by ths nterface. - programmng of the text dsplay by PG 675 or PG programmng the text dsplay by PC - connecton of the text montor LCA connecton of another for the copyng of all programmed nformaton

14 -TEXT DISPLAY... -THE FUNCTION OF THE PUSH BUTTONS s no button, the LED s nform about STROBE and ACKNOWLEDGE MAIN INFORMATION of a message ADDITIONAL INFORMATION of a message MESSAGE BUFFER forward scroll 1.7 PUSH BUTTONS The operaton of the text dsplay s done by 5 front push buttons. Each button s llumnated when ts use s logcal. In case of a false use the LED`s of all buttons flash twce. MAIN INFORMATION OF A MESSAGE TEXT PAGE: By pushng ths button, the dsplays the frst two lnes of a message or a message text page. ADDITIONAL INFORMATION OF A MESSAGE TEXT PAGE: By pushng ths button, the always dsplays the followng lnes of a message or a message text page. Each message text page may have 30 addtonal lnes maxmum. IN THE MESSAGE BUFFER FORWARD SCROLL: By pushng ths button, all messages stored n the message buffer wll be scrolled from the frst to the last message. Ths push button ncorporates AUTO- REPEAT. MESSAGE BUFFER backward scroll call of OPERATIONAL HELP IN THE MESSAGE BUFFER BACKWARD SCROLL: By pushng ths button, all messages regstered n the message buffer wll be scrolled from the last to the frst message. Ths button ncorporates AUTO- REPEAT. CALL OPERATIONAL HELP: By pushng ths button, dfferent help messages are called whch may be addtonally useful to the operatng personnel.

17 -TEXT DISPLAY... -THE COMMUNICATION WITH THE PLC 2.1 COMMUNICATION WITH PLC For the callng of message texts or the nput of external varable data the offers 3 possbltes: 1. dynamc call of message texts or read n of vara-ble data wth STROBE and ACKNOWLEDGE Ths handshake operaton wth the PLC s very safe and smple. 1-BIT orders (AND, FEED, =) are suffcent. The transfer of the PLC data does not need any specal tmng. The reacton tme s an average of 2 msec. 2. dynamc call of message texts or read-n of varable data wth STROBE but wthout ACKNOWLEDGE The transfer of the PLC data takes place relatvely slow (reacton tme 4msec) and the PLC needs an output tmer. 3. statc call of message texts wthout STROBE and ACKNOWLEDGE Ths transfer of PLC data s very smple (STROBE and ACKNOWLEDGE have to be lnked) and extremely quck. Ths call s only possble usng the message varant "DIRECT MESSAGE".

18 -TEXT DISPLAY... -THE MESSAGE NUMBER AND MESSAGE TEXT PAGE 2.2 MESSAGE NUMBER AND MESSAGE TEXT PAGE The message number ndcates whch message text page wll be called. The message number s coded, thus by a mnmum of message nputs a maxmum of messa-ges can be called. The offers two codng possbltes: MESSAGE TEXT 199 MESSAGE TEXT 001 MESSAGE TEXT 000 BCD BCD BCD BCD BCD BCD BCD BCD BCD message text page message number untl BIN-coded message number, up to 511 pages - BCD-coded message number, up to 199 pages The has 512 message text pages, they have the message numbers The maxmum 14 mes-sage text lnes wth 40 characters per lne each can be attached to the message text pages as needed.

After ths the STROBE sgnal may change to log 0 (tme 5) and the message nputs may be changed by the PLC also. As soon as the PLC has recognzed the acknowlege sgnal t ends the STROBE.

It was untl now necessary to use one PLC flag for each message. Those flags had to be set as soon as the message appeared and to be reset as soon as the message ended. Wth the, the flags and ther management are no longer the task of the PLC but of the, wth the result that the development of PLC software for the steerng of the s much easer and that the PLC has more capacty for t s true purpose. As soon as the PLC recognzes a fault t swtches on the correspondng message n the text dsplay. Ths message wll reman n the message buffer untl the PLC recognzes that the fault has gone and swtches off the message. The has flags for every message whch s why t s not necessary to set or reset flags n the PLC. The PLC can swtch on or off up to 512 messages (flags) n the at any desred tme. A message s swtched on by callng up a text number and nput MESSAGE OFF at low poston. Ths message wll stay n the s message buffer untl the PLC calls up the same text number wth nput MESSAGE OFF at hgh poston. keeps the sequence excactly, dentcal messages are only regstered once.

26 -TEXT DISPLAY... --EXTERNAL VARIABLE DATA MESSAGE INPUTS FUNCTION INPUTS EXTERNAL VARIABLE DATA allows the combnaton of fxed text wth varable data. Ths varable data may be temperatures, pressures, speeds or smlar. They can be wrtten n all the 32 lnes of any of the 512 messages. Each message can show up to 128 dgts of varable data splt n dfferent lnes. EXAMPLE: LINE 1 LINE 2 -OIL-TEMPERATURE 1 = 68.5 C ( 70.0 C) -OIL-TEMPERATURE 2 = 88.9 C ( 84.0 C) BCD-VARIABLE BCD2-VARIABLE BCD2-VARIABLE ASCII-VARIABLE 0 WITHOUT VARIABLES 1 WITH VARIABLES The poston of the varable data s programmed at the same tme as the other text wth placekeepers ( ). Those placekeepers wll be exchanged wth the varable data n the programmng mode.

27 2.9.2 VARIABLE DATA CODE READ IN OF VARIABLE DATA allows a choce between 3 dfferent varable data codes. The set up of those codes s done n menu INITIALISATION: VARIABLE DATA CODE 1: ASCII (8 Bt / 1 Byte) In ths code all ASCII sgns ($00...$FF) are avalable. The transmsson to s done one byte after the other (byte-seral). VARIABLE DATA CODE 2: BCD-2 (2 x 4 Bts / 2 DIGITS) In ths code the numbers ($00...$09) and the addtonal characters PLUS MINUS POINT SPACE + ($0B) - ($0C). ($0E) _ ($0F) At frst the varable s wrtten nto the. The wrte n of the varable data s done dgt after dgt, double-dgt after double-dgt or byte after byte and ts always wrtten from left to the rght. A adressng of the dgt postons s not necessary. The varables reman n the buffer untl a message s called up. Then the varables are transfered from the buffer nto ths message. If a message s called up that does not ft to the prepared varables no transfer or a faulty transfer wll happen. That s why t s mportant that varables and the then called up message ft together. If the varables change t s only necessary to transfer the whole set of varables agan.
