Accessory 79

Introduction 1

INTRODUCTION

The powerful PMAC environment allows many machines to be controlled entirely by PMAC, making the

demand for industrial strength I/O devices for PMAC higher than ever. The ACC-79 interconnects the

latest I/O from OPTO22, Inc. (SNAP I/O) to the PMAC2 family of boards. OPTO22 has developed front-

end processors for their products calling them brain boards or brains.

ACC-79 provides an interface between the PMAC2 J I/O port and OPTO22 type snap modules. The

PMAC2 J I/O port has 32 I/O lines programmable as inputs or outputs, in groups of eight. Therefore, the

OPTO22 modules must be selected as either input or outputs according to the programmable settings of

the PMAC2 J I/O port. ACC-79 is compatible with OPTO22 SNAP-B8M and SNAP-B4M backplanes

and all SNAP digital I/O modules and it is supplied with a 24-inch IDC cable.

JI/O interface.

 Connect the field wiring to each I/O module as required.

Accessory 79 Manual

2 Snap I/O Modules

SNAP I/O MODULES

Field wiring is connected to the terminals of the Opto22 SNAP I/O modules. The purpose of the SNAP

module is to isolate real world signals from PMAC. The isolation is achieved by using optical isolation

components in the SNAP module to separate PMAC’s ground from the I/O ground. In addition, the

SNAP modules provide the opportunity to condition the I/O signals. Typical I/O devices operate at

24Vdc or 120VAC, which is incompatible with PMAC as well as most other electronic devices operating

at 5Vdc. Wide varieties of SNAP modules are available to accommodate different I/O characteristics.

Each SNAP I/O module, regardless of its output characteristics, conditions the I/O to a 5Vdc signal.

These 5Vdc signals are communicated along the back plane to ACC-79.

ACC-79

ACC-79 implements the circuitry and interconnections allowing easy connection of PMAC2’s JI/O

interface to the Opto22 SNAP I/O back plane. There is nothing to adjust internally. The following back

J I/O Interface

The PMAC2 JI/O interface provides 32 programmable I/O channels. The I/O is configurable as inputs or

outputs on a byte-by-byte basis. In addition, an invert control is provided.

The following characteristics of the JI/O port are configurable in software:

 Directional control bits

Direction (input or output) on a byte basis

 Buffer directional control bits

Direction (input or output) on a byte basis

 Inversion control bits

Inversion (inverted or non-inverted) on a bit basis

 Type control bits

Function (JI/O general purpose bit or dedicated function) on a

bit basis

To setup the JI/O interface for the application, define the PMAC M-Variables. The following table

The directional control bits, buffer directional control bits, and type control bits should be set at power up

by a PMAC PLC program. Typically, this program is PLC1 and is set to run once at power up. These

values must be set correctly for proper operation of the ACC-79 and the Opto22 I/O. The following

Note: Since PMAC sets the memory locations pointed to by M42 and M43 to the appropriate values to configure

JI/O as general purpose I/O after power-up or reset, it could be considered optional to set these values in the power-

up PLC used to configure M32 thru M41, as defined above.

Note:

A value of 0 in the control bit sets the corresponding I/O point as non-inverting. A

value of 1 in the control bits sets the corresponding I/O point as inverting. At

power-up/reset, PMAC sets all of the I/O points on the JIO port as non-inverting

automatically.

Direction Control 5

DIRECTION CONTROL

The PMAC2 JIO direction control is used to set up the I/O bytes as either inputs or outputs. The direction

control bit for each of these I/O bits is located in the corresponding bit in the matching X register. For

example, the direction control bit for I/O03 is located at X:$C080,3 and X:$78400,3 for Turbo PMAC2;

the direction control bit for I/O30 is located at X:$C081,6 and X:$78401,6 for Turbo PMAC2. Because

the buffer ICs can only be switched by byte, it is best to define 8-bit M-variables for the direction control.

Suggested definitions are:

PMAC2

Turbo PMAC2

Description

M32->X:$C080,0,8

M32->X:$78400,0,8

Direction control for I/O00 to I/O07

M34->X:$78400,8,8

Direction control for I/O08 to I/O15

M36->X:$C080,16,8

M36->X:$78400,16,8

Direction control for I/O16 to I/O23

M38->X:$C081,0,8

M38->X:$78401,0,8

Direction control for I/O24 to I/O31

These M-variables should take values of 0 or 255 ($FF) only; 0 sets the byte to input, 255 sets the byte to

output.

In addition, the bi-directional buffer IC for each byte has a direction control line accessible as a software

control bit. These control lines and bits must match the ASIC direction bits. The buffer direction control

bits are at PMAC address Y:$E800 or Y:$70800, with bits 0 to 3 controlling the four bytes of the JIO

port. A bit value of 0 specifies input; 1 specifies output. Suggested M-variable definitions are:

PMAC2

Turbo PMAC2

Description

M33->Y:$E800,0

M33->Y:$70800,0

Buffer direction control for I/O00 to I/O07

Buffer direction control for I/O16 to I/O23

M39->Y:$E800,3

M39->Y:$70800,3

Buffer direction control for I/O24 to I/O31

In the default configuration automatically set at power-up/reset, I/O00 to I/O31 are set up as inputs. This

is done for maximum safety; no lines can be forced into an undesirable high or low state. Any of these

lines that are to be used as outputs must be changed to outputs by user programs (usually, this is done in

PLC 1 acting as a reset PLC, scanning through once on power-up/reset, then disabling itself).

Accessory 79 Manual

6 Inversion Control

INVERSION CONTROL

Each line on the JIO port is individually controlled as to whether it is an inverting I/O point (0=+5V;

1=0V) or a non-inverting I/O point (0=0V; 1=+5V).

PMAC2

Turbo PMAC2

Description

M40->X:$C084,0,24

Inversion control for bits 0 to 23

M41->X:$C085,0,8

M41->X:$78405,0,8

Inversion control for bits 24 to 31

A value of 0 in the control bit sets the corresponding I/O point as non-inverting. A value of 1 in the

control bits sets the corresponding I/O point as inverting. At power-up/reset, PMAC sets all of the I/O

points on the JIO port as non-inverting automatically.

Each general-purpose I/O point on the JIO port has an alternate use as a supplemental fixed-use I/O point

on a supplemental machine interface channel (1* or 2*). The points are controlled individually as to

general-purpose use or fixed use by control registers Y:$C084 and Y:$C085. Refer to these registers in

the memory-I/O map to see the alternate uses of each point. At power-up/reset, PMAC2 sets up all of the

I/O points on the port for general-purpose use automatically.

Note:

The direction-control of the buffer ICs must be set properly for the alternate uses

of the I/O points, just as for the general-purpose I/O uses.

EXAMPLE SETUP

For this example, the first two bytes of the JIO port are set up as inputs and the last two bytes are set up as

outputs. The logic for all inputs and outputs will be non-inverting (0=0V; 1=+5V).

If the above definitions were made, set these variables to their proper values in an initialization PLC. Use

the following technique for an initialization PLC:

OPEN PLC 1 CLEAR

DIR_CONTROL_1 = 0 ;set as input

BUF_CONTROL_1 = 0

DIR_CONTROL_2 = 0 ;set as input

BUF_CONTROL_2 = 0

DIR_CONTROL_3 = 255 ;set as output

BUF_CONTROL_3 = 1

DIR_CONTROL_4 = 255 ;set as output

BUF_CONTROL_4 = 1

INV_CTRL_0_23 = 0 ;set as non-inverting

INV_CTRL_24_31 = 0 ;set as non-inverting

TypeSlots0_5=$ffffff ;General Purpose I/O(Not dedicated functions)

TypeSlots6_7=$ff ;General Purpose I/O(Not dedicated functions)

;

disable plc1

close

Using this technique, there will be a one-time read of the initialization variables used by the card and the

logic for the PLCs.

Make sure that the configuration is downloaded, that I5=2, and then issue a SAVE and $$$ command.

PLC1 will run only once and the IO should be working.

Software

The OEM is responsible for developing the software to access the SNAP I/O and to utilize this

information in a system. During the development and testing of the ACC-79, there are a number of

programs which may be helpful in the development of the OEM software. These routines are provided

for informational purposes only. Delta Tau does not accept any responsibility for the OEM application or

equipment. The OEM must review the software provided, decide how much is applicable to a specific

application and develop the software appropriate to the application at hand.

12 Component Installation

COMPONENT INSTALLATION

The SNAP I/O system is made up of modular components that are simple to install. SNAP’s innovative

new packaging allows components to simply snap in place. These installation notes give the information

required for the mechanical installation of all SNAP I/O system components and options.

Note:

If using the DIN rail mounting option, skip the Standard Panel Mounting section.

Refer to the extrusion dimensional drawing only to determine the appropriate

clearance for circuit board and ID plate options.

Standard Panel Mounting

Mount the SNAP rack assembly horizontally, as shown in the diagram, if not using module hold-down

screws.

Preferred Method: Template

(product on site)

1. Use the SNAP rack mounting extrusion as a template.

2. Be sure to use the drawing to determine required the product and option clearances.

Alternate Method: Prefabrication of Panels

(no product on site)

1. Mounting holes are in sets of two, located on the lower left and the upper right with respect to a

centerline (CL).

2. Using the drawing, determine the (CL1) mounting hole positions. (CL1 is located on the left side of all

SNAP rack mounting extrusions).

3. Use the center-to-center length specification table to determine the offset between the centerlines and

the number of centerline positions for each model.

4. Repeat the process for each centerline position.

Note:

The dimensions shown in the diagram apply to all models.
