Allen-Bradley Ethernet Driver
Note: The number of array elements (in bytes) cannot exceed the block request size specified. This means
that array size cannot exceed 16 words given a block request size of 32 bytes. For more information, refer to
Block Request Size.
File Numbers and Word Locations
The following file numbers and maximum word locations are allowed for each model. The maximum word loc-
ation is one less when accessing as a 32-bit data type (Long, DWord or Long BCD).
PLC Model File Number Max. Word

PLC-5 Family 3-999 1999
SoftPLC 3-9999 9999
Example Description
N7:0 Word 0
N7/26 Bit 26
N12:4/15 Bit 15 word 4
N7:10 [8] 8 element array starting at word 10
N15:0 [4][5] 4 by 5 element array starting at word 0
N7/12 [9] 9 element Boolean array starting at bit 12
N7/19 [3][11] 3 by 11 element Boolean array starting at bit 19
N7:7/0 [10] 10 element Boolean array starting at bit 0 word 7
N7:29/13 [2][15] 2 by 15 element Boolean array starting at bit 13 word 29
Float Files
To access Float files, specify a file number and an element. The only data type allowed is Float.
Syntax Data Type
F<file>:<element> Float
F<file>:<element> [rows][cols] Float array
F<file>:<element> [cols] Float array
Note: The number of array elements (in bytes) cannot exceed the block request size specified. This means
array size cannot exceed 8 floats given a block request size of 32 bytes. For more information, refer to Block
Request Size.
File Numbers and Word Locations
The following file numbers and maximum word locations are allowed for each model.
PLC Model File Number Max. Word
