Detalles del driver:

XABSLC5 allows you to use full-duplex DF1 protocol (System point-to-point) to communicate with ALLEN-BRADLEY SLC-500 PLCs using any of the following

adapters connected to the PC's RS-232 port:

Channel 0 located in the processor

1747-KE (DH-485)

1785-KE (Data Highway Plus)

1770-KF2 (Data Highway Plus)

1770-KF3 (DH-485)

1771-KE/KF (Data Highway)

1770-KF2 (Data Highway)

No additional boards are required in the PC bus.

To minimize the number of messages needed to poll all the required information, it is a good idea to concentrate all data to be transmitted in groups of consecutive integers within the PLC memory. Up to 16 ON/OFF status, 1 16-bit value, 2 8-bit values or even floating-point values (scaled to a range of 0 to 65535) can be encoded in each integer value sent or received.

SLC-500 Addressing Format This convention for accessing to the SLC-500 controllers' data

is used by the following SLC-500 commands:

Generic Read

Generic Write

The general format of item names for data from SLC-500 controllers matches the naming convention used by the programming software. The format is shown below. (The parts of the name shown in square brackets ( ) are optional.)

X FILE : ELEMENT .FIELD /BIT

X:

Identifies the file type. The list below summarizes the valid file types and the default file number for each type:

X File Type Default File O *Output 0 I *Input 1 S Status 2 B Binary 3 T Timer 4 C Counter 5 R Control 6 N Integer 7 F **Floating P. 8

* Output and Input file types may be Read Only depending on the SLC-500 model. ** Available only on certain SLC500 models. Check the Processor Manual for the model being used. If the Floating Point file type is not supported, file 8 is reserved and unusable.

FILE:

File number must be 0-255 decimal. File 0 must be Output, file 1 must be Input, file 2 must be Status and so on for all the default file types. If this number is not specified, the default file number will be used.

ELEMENT:

Element number within the file. For Input and Output files it must be between 0 and 30 decimal. All other file types, it must be between 0 and 255 decimal.

FIELD:

Referes to the subelement number. If the file type is Timer, Counter or Control, then the subelement field must be replaced by its corresponing number. In some cases there is no reference needed for a subelement number, and if a subelement is included in the command, it will be ignored.

BIT:

Valid for all file types except Floating Point. Must be 0-15 decimal.

DESCRIPTION OF THE AVAILABLE FILE ITEMS:

----------------------------------------

OUTPUT FILE ITEMS:

On:e.s/b

"n" represents the file number and is optional. If not specified, it is assumed to be zero.

"e" indicates the element number in the file.

"s" indicates the sub-element number (0 - 255).

"b" specifies the bit (0 - 15 decimal.) "/b" may be omitted if necessary to treat the I/O group as a numeric value.

Examples:

O0:0/0

O:2/15

O:3

INPUT FILE ITEMS:

In:e.s/b

"n" represents the file number and is optional. If not specified, it is assumed to be one.

"e" indicates the element number in the file.

"s" indicates the sub-element number (0 - 255).

"b" specifies the bit (0 - 15 decimal.) "/b" may be omitted if necessary to treat the I/O group as a numeric value.

Examples:

I1:0/0

I:2/15

I:3

ADDRESSING I/O MODULES:

The elements (words) in I/O modules are mapped into a memory table. If the Analog I/O modules are being used, then the point naming will differ from the point naming in the programming software. The Item Name must be computed from the sum total of words used by the previous input or output blocks regardless their relative position in the module rack. The operator can use the programming software Data Monitor to look at the memory map of the I file or O file to verify your address. If the address is unsure, or if the PLC configuration is likely to change, copy the points in question to the N table or B table and access the data from there.

LABEL I/O MODULES WITH "WORD COUNTS":

The address of any point within the I/O datatable space, in an SLC processor, is the sum of the words occupied by previous modules (to the left in the rack) of the same type. Therefore, to determine the correct address for any particular point in the I/O datatable, one must know the number of words each module will consume. Refer to the list below:

N. of Words Module

0 1747-L524 SLC 5/02 Module Processor
1 1746-IA8 8 point 120VAC input module
1 1746-OA16 16 Point 120VAC output module
1 1746-IA16 16 point 120VAC input module
4 1746-NI4 4 point 20mA analog input module
4 1746-NO4I 4 point 20mA analog output module
1 1746-0A8 8 point 120VAC input module
2 1746-IB32 32 point DC input module

Nota importante:

In the table above, the minimum amount of words which can be consumed by a module is 1 (16 bits). This is due to the memory scheme of all Allen-Bradley processors.

STATUS FILE ITEMS:

Sn:e/b

"n" represents the file number and is optional. If not specified, it is assumed to be two.

"e" indicates the element number in the file (0 - 255 decimal).

"b" is optional. If specified, it indicates the bit (0 - 15 decimal).

Nota importante:

Refer to the SLC-500 Family Processor Manual (Allen-Bradley Publication) for a complete description of Status file information.

Examples:

S2:6 (major error fault)

S2:13 (math register)

S:1/5 (forces enabled)

BINARY FILE ITEMS:

Bn:e/b or Bn/m

"n" represents the file number and is optional. If not specified, it is assumed to be three. If specified, the file number must be between 9 and 255 decimal.

If you are using 1747-KE

IMPORTANT NOTES:

---------------- Remember to configure the 1747-KE using the following settings:

Use the DF1 FULL DUPLEX Protocol

Use the checksum mode (BCC or CRC) as stated in HMITalk1.DriverP5 parameter.

Use the baud-rate, parity, stop bits and data bits that are currently used in the driver settings.

You should verify these settings by connecting your PC to the 1747-KE CONFIG port using an ASCII terminal (i.e. PROCOMM or XTALK) and then follow the steps described in the 1747-KE User Manual.

Be careful to include the 1747-KE node address as the source node in your HMITalk1.DriverP0 parameter if it is other than 0.
