Supported device types and versions


The protocol Allen-Bradley CSP/PCC supports communication with Allen-Bradley devices of the SLC-500 series through a TCP connection.
It also supports communication via DF1 gateway with SLCs that communicate via DH+ or DH485.

Communication line configuration


Station configuration


  • Communication protocol: "Allen-Bradley CSP/PCC".
  • Station address is not configured.

Station protocol parameters

Dialog window station configuration - tab "Protocol parameters".
They influence some optional protocol parameters. The following station protocol parameters can be entered:

Parameter Description Unit Default Value
Response Wait Timeout Timeout to receive a response from PLC. s 1.000
Retry Count Number of request retries in case of a communication failure. - 3
Destination Node Address If using a DF1 gateway, the node address of the destination device in question (e.g. on DH+ or DH485 node). If the DF1 gateway is not in use, the default value of 0 must be used. - 0
Block Read Activates the block reading mode (types Integer, Binary, Status, Float, Timer a Counter). Types Input and Output don't support block reading mode. YES/NO NO
Max. Block Length Maximum block size (2-255 bytes) if block reading mode is active. bytes 40
Full Debug Activates detailed listings about sending and receiving values. - False

I/O tag configuration


Possible I/O tags: Ai, Ao, Ci, Co, Di, Dout.

The address of I/O tag is a text in a format SLC-500. The address format is:

[$] X [file] : element [.field] [/bit]

Explanatory notes:

$ - optional character
X - file identifier (required - see Table 2)
file - file number (optional, if it is empty, the default file number is used - see Table 2)
element - element number in the file (required)
.field - number of sub-element (optional, it is used only for Output, Input files)
/bit - bit number (optional, it must be in the range of 0..15)

Table 2

X File Type Default file number (file)
O Output 0
I Input 1
S Status 2
B Binary 3
T Timer 4
C Counter 5
N Integer 7
F Float 8

File type - Output

[$]O[n]:e[.s][/b]

"n" - file number, if there is used other than the default number 0,
"e" - number of element in a file,
"s" - number of sub-element (0..255),
"b" - bit number (0..15).

Example:

O:2
$O0:2/0
O:1.0/1

Note: The files of Output type are read-only.


File type - Input

[$]I[n]:e[.s][/b]

"n" - file number, if there is used other than the default number 1,
"e" - number of element in file,
"s" - number of sub-element (0..255),
"b" - bit number (0..15).

Example:

I:1
$I1:2/0
I:2.0/15

Note: The files of Input type are read-only.


File type - Status

[$]S[n]:e[/b]

"n" - file number, if there is used other than the default number 2,
"e" - number of element in file,
"b" - bit number (0..15).

Example:

S:0
$S2:40
S:2/15

Note: As regards the files of Status type, data can not be written bit-by-bit (input tags with the parameter [/b]).


File type Binary

[$]B[n]:e[/b]

"n" - file number, if there is used other than the default number 3,
"e" - number of element in file,
"b" - bit number (0..15).

Example:

B:2
$B3:0
B3:2/1

File type - Timer

[$]T[n]:e[/b]

"n" - file number, if there is used other than the default number 4,
"e" - number of element in file,
"b" - optional prefix /EN, /TT, /DN (bit values) or /PRE, /ACC (integer values).

Example:

T:2
$T4:0/ACC

File type - Counter

[$]C[n]:e[/b]

"n" - file number, if there is used other than the default number 5,
"e" - number of element in file,
"b" - optional prefix /DN, /CU, /CD, /OV, /UN, /UA (bit values) or /PRE, /ACC (integer values).

Example:

C:17
$C5:34/DN

File type - Integer

[$]N[n]:e[/b]

"n" - file number, if there is used other than the default number 7,
"e" - number of element in file,
"b" - bit number (0..15).

Example:

N7:2
$N:0
N27:0/1

File type - Float

[$]F[n]:e

"n" - file number, if there is used other than the default number 7,
"e" - number of element in file.

Example:

F:0
$F8:0
F29:1
