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
- Communication line category: TCP/IP-TCP.
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,

"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,

"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:
