CALL 28: Write to Remote DH-485 SLC Data File
CALL 28 writes up to 99 words of data from the ControlLogix processor (or
MVI56-BAS string) to a remote DH-485 node data file. The DH-485 section in this
User Manual explains how to implement this BASIC CALL in detail.
Note: If using an internal string as the destination file, you may use CALL 29 to initiate the data
transfer without ladder logic.
Syntax:
PUSH [A]
PUSH [B]
PUSH [C]
PUSH [D]
PUSH [E]
PUSH [F]
PUSH [G]
PUSH [H]
PUSH [I]
PUSH [J]
CALL 27
POP [S]
Where:
A = Type of DH-485 SLC Write Command to be issued. The following types are
supported:
Code Command
0 Disable the previously executed CALL 28
1 Common Interface File Write
2 SLC Type Write
B = Node address of the SLC remote device (0 through 31)
C = File Number on the SLC remote device (0 through 255)
D = File type to be written to the remote device. The following types are
supported.
File Type Code File Type Name Words/Elements Valid Range
ASC(N) Integer File 1 word/element 1 to 99
ASC(C) Counter File 3 words/element 1 to 33
ASC(T) Timer File 3 words/element 1 to 33
ASC(B) Bit File 1 word/element 1 to 99
ASC(R) Control File 3 words/element 1 to 33
E = The word offset on the remote device file (0 through 32767)
F = Number of word to be transferred. Refer to the previous table for possible
values. If using the Common Interface File, use a value between 1 and 64.
G = Message Time out (1 through 255 For example, 1 = 100ms, 25 = 250 ms,
and so on.)
