AutoMax/DCS5000 variables are mapped to the AutoMate image

area during configuration and can be accessed by any task in any

AutoMax/DCS5000 Processor in the rack. (Refer to section 4.3 for

more information regarding configuration). When AutoMax/DCS5000

variables are referenced in application tasks, the data is directly

obtained from/written to the AutoMate image. When data is received

from the network, it is interpreted by the AutoMax RĆNet Processor

and placed into the AutoMate image. Data transmitted over the

network is also obtained from the AutoMate image.
Register values may be read using the I/O Monitor function of the

AutoMate Programming Executive software. However, the AutoMate

image register number must be converted to the register number

required by the I/O Monitor function (i.e., the actual memory address

that corresponds to the AutoMate image address.)
To calculate the I/O Monitor register number for AutoMate image

registers 0 through 777, first convert the AutoMate image register

number from octal to decimal and then add 64.
Example:
AutoMate Image Register 137

137 (octal) = 95 (decimal)

95 + 64 = I/O Monitor Register 159
To calculate the I/O Monitor register number for AutoMate image

registers 2000 through 5777, first convert the AutoMate image

register number to decimal and then subtract 448.
Example:
AutoMate Image Register 3025

3025 (octal) = 1557 (decimal)

1557 Ć 448 = I/O Monitor Register 1109
Refer to the AutoMax Programming Executive instruction manual for

more information regarding the I/O Monitor function.

Globals
Global coils are used to communicate between various AutoMate

Programmable Controllers when they are connected via the RĆNet

network. Each AutoMate has a dedicated group of addresses for this

function. Refer to figure 4.4. When a global coil is programmed in

one node, its status is broadcast to all nodes on the network every

token.
