The following is a list of commands for the secondary parser:

Command

 

 

Response

/a#/

the content of a#, where: a = A, D*, F, P and U

 

# = 0 through 9

 

 

e.g.

/P5/

the content of P5

*D parameters are the only parameters which may be altered through the secondary command parser (which bypasses the security parameter F0). This may be useful, for example, in periodically reading and then resetting the short total, ‘D2’. The protocol for altering the value of a D parameter via the secondary parser is:

/dn=#/

where: n is parameter number

#is the value stored in the parameter

e.g. /d4=50/, this sets the minimum flow rate to 50 for D4

/t0/

totalizer value, similar to that of the ‘Flow and Total’

 

(F2) display, except that the multiplier is not displayed

/t1/

totalizer value, returned as a floating point number with

 

a maximum of 6 decimal places, modified to include the

 

effect of the totalizer multiplier.

 

e.g. if the OCM-3 display shows 00005678 x 100, the

 

response would be 567800.000000

/t2/

returns the current 24 hour time: hh:mm:ss

/t3/

returns the current date: dd/mm/yy

/f/

returns the current flow rate

 

this is similar to the OCM-3 parameter F2 display, however it

 

is not subject to truncation to less than 6 decimal places.
