Part IV Configuring the Allen-Bradley Data Highway Driver.
After loading the driver, an icon will appear under the Application Manager labeled Allen- Bradley Data Highway (ABDH). To configure the driver:
Step 1 ) Double-click on the icon labeled Allen-Bradley Data Highway (ABDH).
The Allen-Bradley Data Highway configuration pop-up window will appear. This window should contain 5 tabs as shown in Figure S. The tabs are titled, 1) COM Port, 2) Protocol, 3) PLC Stations, 4) Watchdog, 5) Write Buffering.
The complexity of your application will determine which tabs need to be configured. In our basic example, we will only be concerned with the first three tabs. The definition of each field within the tabs can be found by selecting the [HELP] button on the bottom of the configuration window.
Step 2 ) On the COM Port tab, change the Port Number to the communication port that the cable is connected to from Step 1. COM 1, 2, 3 or 4 are the options. The other settings are the default settings and should be left alone.
Step 3 ) Select the Protocol tab.
For the example above (figure T), the default values for Acquisition Rate, Data Highway Timeout, ASCII Terminator Character and Maximum ASCII Length are sufficient.

To set up the station:
Step 5 ) Select the [Add] button.
A window will appear similar to figure U where you input the Station Number in octal. In the above example, station number 10 was used.
The station number must match the PLC node address. There are two different ways to find out what address a PLC is configured for: 1) by looking at the dip switches on the PLC hardware and 2) by navigating into the Channel Configuration screen within the A-B PLC programming software.
Step 6 ) Select the [OK] button.
At this point the station has been added to the Station Listing box as shown in FigureV. You have the option to define the type of PLC and whether the PLC is active during startup or not.
Step 7 ) Select the PLC-5 option as the PLC type.
Step 8 ) Select the Active as the Startup option.

PLC-3, PLC-5, SLC-500 Addressing Format (continued)
Note: The bit number is used for the number of characters in the string for the ASCII data type. If omitted,
the string length for read operations will default to the Maximum ASCII Length.
Memory Types
Floating point (F) and high order integer (H) memory types do NOT support bit addressing. If a bit number
is used with these memory types, a question mark (?) will be placed over the tool upon entering the Run
mode.
Note: The SLC-500 does not support the following types: DT, D or H.
All timer (TP, TC, TA) and counter (CP, CC, CA) memory types support bit addressing for READ tools only. If a bit number is used on a write tool with these memory types, a question mark (?) will be placed over the tool upon entering the Run mode.
Note that D and DT reference the same memory but are interpreted differently.
Note that ST is only supported by the PLC-5 and SLC-500.
The following memory types are supported for the SLC-500 only:
An ASCII data type modifier (A) can be used with the N (integer) file type. You can not use the ASCII
modifier with any other file type.
For example: SLC5\1$NA7:2 is displayed as an ASCII string.
Memory Types
Note: The SLC-500 does not support the following types: DT, D or H.

For example: SLC5\1$NA7:2 is displayed as an ASCII string.
PLC-3, PLC-5, SLC-500 Addressing Format (continued)
File Numbers
File numbers 0, 1, and 2 are reserved in the PLC-5, 0 through 8 are reserved in the SLC-500. The PLC-3 enables any file number from 0-999 to be used with any memory type.
0 = output 1 = input
2 = status 3 = bit
4 = timer 5 = counter
6 = control 7 = integer
8 = floating point9-999 = for additional file storage
Mnemonics
The following mnemonics may be used in place of the SUBELEMENT number in a SLC-500.
PRE: preset LEN: length
ACC: accumulator POS: position
For example: ABDH\1$T4:1.PRE
The following mnemonics may be used in place of the BIT number for the SLC-500.
EN: enable bit EM: stack empty bit
CU: count up bit UN: underflow bit
TT: timing bit ER: error bit
EU: unload enable bit UA: update accum bit
CD: count down bit UL: unload bit
DN: done bit IN: inhibit bit
OV: overflow bit FD: found bit
For example: ABDH\1$T4:1,EN
Examples
ABDH\16$N7:2
driver name: ABDH
PLC station number: 16
memory type: N for integer
file number: 7
offset number: 2
ABDH\25$B3:2.5
driver name: ABDH
PLC station number: 25
memory type: B for binary
file number: 3
offset number: 2
bit number: 5
