The number of words in the table depends on the choice of states and commands that are to be processed via the dialog.
So, the number of available words depends on the PLC type (For example : presence or not of function keys).
Notation convention for describing the table
%MWn word of 16 bits
%MWn, i : bit i of word n
The address n is taken as the start of table address.

Only XBT-E possesses a protected real-time clock. The XBT writes the time and date periodically to the PLC (approximately every second).
2 coding formats are possible:
Hexadecimal or BCD (option selected with XBT-L1000).
WARNING
UNINTENTIONAL EQUIPMENT OPERATION
If communications between XBT and PLC are lost, operator's control over machine may be lost completely or partially. It is designer's responsibility to program PLC logic to account for this situation. One of the good ways to do that is to monitor %MWn+4 of the dialog table from the PLC program.
Failure to follow this instruction can result in death, serious injury, or equipment damage.
%MWn+9 : Number of page to be displayed
N ° of the page displayed on the terminal and to be sent to the PLC.
It contains H'FFFF' if it is a system page or a displayed alarm.
%MWn+10 : Number of last field entered
N ° of last field entered on the terminal to be sent to the PLC.
%MWn+11 : Last alarm accepted
This information is only present on one PLC scan, it then returns to
H'FFFF'.

%MWn+13 : Log occupancy rate
The occupancy rate of the alarm log as a % on the terminal and to be sent to the PLC.
%MWn+14 : Page number to be processed
To process page 22 insert 22 -> %MWn+14
When %MWn+9 = 22 and %MWn+14 = H'FFFF' the command is OK
When %MWn+9 < > 22 and %MWn+14 = H'FFFF' the command is not OK
Special commands:
Page N°: 65521 normal Brightness
Page N°: 65522 low Brightness

%MWn+15 : Field number to enter
If the field 20 is to be entered on page 10 :
* confirm that %MWn+9 = 10
* then 20 -> %MWn+15
When %MWn+10 = 20 and %MWn+15 = H'FFFF' the command is OK.
%MWn+12 then gives more detail : "ENTER on entry".
When %MWn+10 < > 20 and %MWn+15 = H'FFFF' the command is not OK
%MWn+12 then gives more detail : " ESC Time-out".

Ex.
%MWn+16 : Print command
MSB : Print code LSB : Long Tab
A code is assigned to each possible print type.
- free format print :
- print sheet :
01 (nb octets)
04 (n° page 0 to 127)
- print log :
- "Hard-copy" Display:
02 (00)
05 (n° page 0 to 127)
For free format printing, the PLC gives the length in bytes of the information to be printed (maximum 40 words) in the LSB. The terminal reads the length given in word table to the end of dialog table address +
1. For sheet print, the LSB represents the N ° of sheets.
The word "Print command" is written by the PLC.
This same word is written to H'FFFF' by the XBT, to acknowledge the end of the command.
%MWn+17 : Writing table authorization
MSB LSB
For a 20 words long table, the PLC can write to the authorization word
H'A514'.( A5= authorization, 14= Nbr of words in dialog table
Hexadecimal value)
%MWn+18 : Reset log
The PLC writes H'00FF' in this word.
- the XBT clears the log and resets the "log occupancy rate" (%MWn+13).
- the PLC must writes H'0000' in the word %MWn+18 to accept a new
Reset Log command .
