Mask (Three Address Fields)
Column Parameter Description Parameter
1 Enable/Type Word 0=Disabled, 1=Continuous and 2=Conditional.
2 Virtual Database Address This parameter defines the database address of the
data to be associated with the command. The first
word of data contains the bit mask and the second

3 Poll Interval Minimum time in tenths of a second to wait before
polling with this command.
4 Count Number of data word values to be considered by the
function.
5 Swap Type Code Swap type code for command: Always zero (0).
6 Node Address Address of unit to reach on the data highway.
7 Slot Number Processor slot number in Control/CompactLogix rack.
Use -1 for PLC5 & SLC processors.
8 Function Code = 511 Logical Write with mask
9 File Type SLC file type letter as used in file name string. Valid
values for the system are N, S, F, A, …. P1
10 File Number SLC file number to be associated with the command. P2
11 Element Number The parameter defines the element in the file where

This function writes one or more words of data from a PLC data table controlling
individual bits in the table. The bit mask used for the command is 0xFFFF. This
provides direct manipulation of the data in the device with the internal data of the
module. The function requires that all data associated with the command use the
same mask.
