n represents the file number (NOT optional) and must be 3 - 999 decimal. |
|
e specifies the element number within the PID file. It must be 0 - 398 decimal. |
|
|
f identifies one of the valid PID fields. The valid fields for PID files are listed in the table. If PID field .ADDR is needed, use .ADRE for element and .ADRF for file. |
|
|
b is optional and is normally not used. All of the fields of a PID can be accessed by specifying the .f fields. If specified, it indicates the bit (0 - 15 decimal). |
Important: Access to PID files may degrade the Communication Driver's performance due to the extreme size of the PID element (82 words each). If accessing only a few PIDs at a time, performance will not be greatly affected. If accessing a few fields of many PIDs at the same time, it may be faster to move the needed fields to an intermediate file (Floating Point or Binary) and let the Communication Driver access the intermediate files.
Examples:
PD9:2.SP
PD9:3.OLH
PD9:0.INI
