14.8 Related to OEM parameters
These variables are read-only (R) synchronous and are evaluated execution time.
They have generic names.
• Replace the letter "i" with the parameter number keeping the brackets. This number
corresponds with the parameter number in the machine parameter table. For example, the
parameter that appears in the MTBPAR table as P0 will be accessed as (V.)MTB.P[0].
When reading the (V.)MTB.P[i] variable from the PLC, it truncates the decimal portion. The
(V.)MTB.PF[i] variables return the parameter value multiplied by 10000.
DATA = 54.9876
(V.)MTB.P[10] = 54
(V.)MTB.PF[10] = 549876
The access to drive variables may be either to read or write depending on how it has been set in the
machine parameter table. Likewise, the type of access to these variables from the PLC, synchronous
or asynchronous, is also defined in the machine parameter table.
