The Allen-Bradley CSP/PCC PCCC protocol supports communication with the Allen-Bradley devices of the SLC-500 series using a TCP connection.
It also supports communication via the DF1 gateway with SLCs that communicate via DH+ or DH485.
Communication was tested e.g. with the following SLC:
- SLC 5/05 1747-L551/C Ethernet Processor
- SLC 5/05 1747-L552/C Ethernet Processor
- SLC 5/05 1747-L553/C Ethernet Processor
Note: PCCC message encapsulation is also supported within the Ethernet/IP Protocol (communication with MicroLogix 1100 or SLC 5/05 1747-L553/C Ethernet Processor)

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 | ||||||
|---|---|---|---|---|---|---|---|---|---|
| Timeout to receive a response from PLC. | s | 1.000 | ||||||
| The number of the request retries in case of a communication failure. | - | 3 | ||||||
| If using a DF1 gateway, the node address of the destination device (node) on a DH+ or DH485 bus. If the DF1 gateway is not in use, the default value of 0 must be used. | - | 0 | ||||||
| Activates the block reading mode (for Integer, Binary, Status, Float, Timer, and Counter types). Input and Output types don't support block reading mode. | YES/NO | NO | ||||||
| Maximum block size (2-255 bytes) if a block reading mode is active. | bytes | 40 | ||||||
| Activates detailed listings about sending and receiving values. | - | False |

Possible I/O tags: Ai, Ao, Ci, Co, Di, Dout.
The address of the I/O tag is a text in a an SLC-500 format. The address format is:
...
| 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
[$]O[n]:e[.s][/b]
"n" - the file number, if it is different from the default number 0,
"e" - the number of an element in a file,
"s" - the number of a sub-element (0..255),
"b" - the bit number (0..15).
...
Note: The files of the Output type are read-only.
File type - Input
[$]I[n]:e[.s][/b]
"n" - the file number, if it is different from the default number 1,
"e" - the number of an element in file,
"s" - the number of a sub-element (0..255),
"b" - the bit number (0..15).
...
Note: The files of Input type are read-only.
File type - Status
[$]S[n]:e[/b]
"n" - the file number, if it is different from the default number 2,
"e" - the number of an element in file,
"b" - the bit number (0..15).
...
Note: As for the files of Status type, data can not be written bit-by-bit (input tags with the parameter [/b]).
File type Binary
[$]B[n]:e[/b]
"n" - the file number, if it is different from the default number 3,
"e" - the number of an element in file,
"b" - the bit number (0..15).
Example:
B:2 $B3:0 B3:2/1
File type - Timer
[$]T[n]:e[/b]
"n" - the file number, if it is different from the default number 4,
"e" - the number of an element in file,
"b" - an 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" - the file number, if it is different from the default number 5,
"e" - the number of an element in file,
"b" - an 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" - the file number, if it is different from the default number 7,
"e" - the number of an element in file,
"b" - the bit number (0..15).
Example:
N7:2 $N:0 N27:0/1
File type - Float
[$]F[n]:e
"n" - the file number, if it is different from the default number 8,
"e" - the number of an element in file.
Example:
F:0 $F8:0 F29:1
