Hardware Address Limitations
The ACC-11E has a hardware address limitation relative to the newer type B series of UMAC high-speed
I/O cards. These new I/O cards have four base addresses per chip select (CS10, CS12, CS14, and CS16).
This enables these cards to have up to 16 different addresses. The type A cards have one base address per
chip select but also have the low-byte, middle-byte, and high-byte type of an addressing scheme and thus
allow for a maximum of twelve of these I/O cards.

Addressing Type A and Type B accessory cards requires attention to the following set of rules:
Populating Rack with Type A Cards Only (no conflicts)
In this mode, the card(s) can use any available Address.
Note
Type A cards can have up to 4 different base addresses. Because
each card can be setup to use the lower, middle, or high byte of a
specific base address, it is possible to populate a single rack with a
maximum of 12 Type A accessory cards.
Populating Rack with Type B Cards Only (no conflicts)
In this mode, the card(s) can potentially use any available Address.
Populating Rack with Type A & Type B Cards (possible conflicts)
Typically, Type A and Type B cards should not share the same Chip Select; however, if they do, the
following rules apply:
Type A and Type B Feedback Cards
Type A cards cannot share the same Chip Select as Type B Feedback cards.

ACC-11E User Manual
Addressing and Jumper Settings 12
Type A and Type B General I/O Cards
Type A cards can share the same Chip Select as Type B general I/O cards; however, in this mode,
Type B cards naturally use the lower byte (default), and Type A cards must be set to the
middle/high byte of the selected base address.
Type A Cards and Type B Analog Cards
Type A cards can share the same Chip Select as Type B analog I/O cards; however, in this mode,
Type B cards naturally use the middle/high bytes (default), and Type A cards must be set to the
low byte of the selected base address.

ACC-11E User Manual
Using ACC-11E with UMAC Turbo 13
USING ACC-11E WITH TURBO UMAC
The procedure for using the ACC-11E with Turbo UMAC has two steps:
1. Configure the Control Word
2. Accessing I/O data points (M-Variables)
Configuring the Control Word
Write a 7 to the control word which is located at {base address + 7}, n, 8 where:
n = 0 if using low byte addressing
n = 8 if using middle byte addressing
n = 16 if using high byte addressing
The control word must be configured every time the UMAC is powered or reset. This can be done in an
initialization (one that disables itself) PLC.
Example 1: Setting up Control Word at Startup for Card at Base Address $78C00, Low Byte Addressing
M3307->Y:$78C07,0,8 // I/O Card 1 control register from suggested M-Variables
Open PLC 1 Clear
M3307=$07
Disable PLC 1
Close
Example 2: Setting up Control Word at Startup for 3 Cards at Base Address $78C00; Low, Middle, and
High Byte Addressing
M3307->Y:$78C07,0,8 // I/O Card 1 control register using low byte
M3317->Y:$78C07,8,8 // I/O Card 2 control register using middle byte
M3327->Y:$78C07,16,8 // I/O Card 3 control register using high byte
Open PLC 1 Clear
M3307=$07
M3317=$07
M3327=$07
Disable PLC 1
Close
Note
See Appendix for control word details and explanations.

Note
Suggested M-Variable definitions are also available with the UMAC
Config. Pro2 tool (see Appendix).
Note
Most systems only use low byte addressing

ACC-11E User Manual
Using ACC-11E with Power UMAC 16
USING ACC-11E WITH POWER UMAC SCRIPT PROGRAMING
The following section describes two software configuration procedures that are needed when using the
Power PMAC script programming language:
1. Configuring the Control Word
2. Accessing I/O data points (pointers)
Configuring the Control Word
Write a 7 to the control word which is located at {base address + 7}.n.8 where:
n = 8 if using low byte addressing
n = 16 if using middle byte addressing
n = 24 if using high byte addressing
The control word must be configured every time the POWER UMAC is powered or reset. This can be
done in an initialization (one that disables itself) PLC, usually PLC 1.
Example: Setting up Control Word at Startup for Card at $A00000, Low Byte Addressing
ptr IoCard0Reg7->u.io:$A0001C.8.8 // I/O Card 0 control register from suggested M-Variables
open plc 1
IoCard0Reg7=$7;
disable plc 1;
close
Example: Setting up Control Word at Startup for 3 Cards at Base Address $A00000; Low, Middle, and
High Byte Addressing
ptr IoCard0Reg7->u.io:$A0001C.8.8 // I/O Card 0 control register from suggested M-Variables
ptr IoCard1Reg7->u.io:$A0001C.16.8 // I/O Card 1 control register from suggested M-Variables
ptr IoCard2Reg7->u.io:$A0001C.24.8 // I/O Card 2 control register from suggested M-Variables
open plc 1
IoCard0Reg7=$7;
IoCard1Reg7=$7;
IoCard2Reg7=$7;
disable plc 1;
close

See Appendix for control word details and explanations.

ACC-11E User Manual
Using ACC-11E with Power UMAC 17
Accessing I/O Data Points (Pointers)
The simplest way to access I/O points on the ACC-11E is to define pointer variables (M-Variables) that
point to each bit on the I/O device.
Suggested M-Variables

Using ACC-11E with Power UMAC 18
USING ACC-11E WITH POWER UMAC C PROGRAMING
Setting Up Digital I/O Access
Delta Tau has developed the following functions which can be used to setup the ACC-11E using the C
Programming Language. The last entry in the list describes, as an alternative, how to create user written
functions.
Function for Setting the Control Word: ACC11E_SetControlWord()
Function for Reading the State of Inputs: ACC11E_GetInputState()
Function for Reading the State of Outputs: ACC11E_GetOutputState()
Function for Writing to Outputs: ACC11E_SetOutputState()
User Written Functions
Function for Setting the Control Word: ACC11E_SetControlWord()
Two parameters must be passed in the calling function:
BaseAddressOffset: One of the four base addresses (jumper selected) ACC-11E can take
=0xA00000
=0xB00000
=0xC00000
=0xD00000
ByteSelect: The byte used (jumper selected) for the I/O bits on this card
=1 for low byte
=2 for middle byte
=3 for high byte
The function is of type void, so it will not return any values.
void ACC11E_SetControlWord(unsigned int BaseAddressOffset, unsigned int ByteSelect)
/*
Input:
BaseAddressOffset: IO Card Base Address offset
ByteSelect: =1 for lowest 8 bits, =2 for middle 8 bits, =3 for high 8 bits
ControlWord: Control word value to which to set the card's Control Word
*/
{
volatile unsigned int *ioptr; // Create I/O pointer
ioptr = piom + BaseAddressOffset/4+ 7;// Initialize I/O pointer to Control Word register
*ioptr = 7<< (8*ByteSelect); // Write Control Word value to register
return;
}
Note
See Appendix for control word details and explanations.
