MODEL 346 INSTALLATION AND OPERATION MANUAL
5.7.6 DATA FORMATS (Cont.)
FORMAT THREE (ACTION EQUATIONS).
Format three allows all possible combinations of triggers to be coded in a 16-character hex word:
>HHHH HHHH HHHH HHHH
Where character 1 comes immediately after the > character.
The table opposite gives details of all the triggers, and the hex values to be inserted into each of the 16 characters.
EXAMPLE 1. An action equation is required to causes a log to occur whenever any of the totalisers (TT1 to TT6),
Timer 4 (TM4), or Alarm four of channel one (A14) gives an output.
In order to achieve this, parameter LQ would have the value >003F080000000040 as follows:
EXAMPLE 2. An ENQ of parameter SQ (alternative chart speed action equation) results in the return of the value:
>0000110100000001
Characters 5, 6, 8 and 16 all have the value 1, and with reference to table 4.8.6b, it can be seen that the
alternative chart speed wil be initiated if Alarm 1 of channels 1, 2 or 3 becomes active, or if the softkey is operated.
